  • Pythium & INSV Infections in Salinas Lettuce Fields

    In 2020 the incidence of Pythium wilt (caused by Pythium uncinulatum) of lettuce has increased in severity and in the number of affected fields. Pythium infections in lettuce fields have been observed frequently, but not always, occurring with INSV infection. As a result, there has been confusion distinguishing between these two diseases and the role of each of them in causing the problems in fields. In this blog we will discuss these two diseases and explain from our current state of knowledge about the disease dynamics occurring in affected fields.

     INSV has been a production problem on lettuce in the Salinas and surrounding valleys for a number of years and in 2020 it continues to be a serious production issue. Pythium wilt of lettuce is a relatively new problem and was first discussed in a blog entry in October 2015 by Steve Koike (https://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=19327 ). However, in 2019 and 2020 we have seen an increase in the number of acres affected by Pythium wilt as well as the severity within fields. Given that Pythium is a relatively new problem and the extent of the problem suddenly increased, some growers and PCAs are confronting this problem for the first time. To add to the confusion, at times INSV and Pythium infections are occurring together on the same plants which has caused confusion and has led to much speculation about the role of each disease in the observed damage.

    Symptoms of INSV

    Issues with INSV infections on head and leaf lettuce types are not a new occurrence in the Salinas Valley and many growers and PCAs are familiar with the symptoms and the patterns of infection in the field, especially on romaine. In general, INSV on lettuce causes characteristic patterns of chlorosis and necrosis on the inner leaves of the plant, as well as significant stunting (Photo 1). However, INSV can cause significant necrosis and lesions on and at the base of the ribs of lettuce plants (Photo 2). It should be mentioned that Tomato Bushy stunt virus (TBSV) can cause symptoms that can be confused with INSV and Pythium wilt; however, lettuce dieback symptoms are always seen on the outer, older leaves and the TBSV pathogen is commonly restricted to low-lying areas along the river. In addition, head lettuce varieties and some romaine varieties are resistant to this virus. When in doubt, it is important to have a sample tested. That said, INSV is the overwhelming virus issue facing growers and PCAs in 2020.

    Viral vs. Fungal Symptoms

    One important detail about lettuce plants infected with only INSV is that they do not exhibit wilting of the outer leaves of the plant or show root rot or root discoloration. This is important to note because in 2019 and 2020 we have visited many fields where the plants exhibit symptoms of INSV and have wilting older leaves. In these situations,  the roots and crowns of the plants should be examined for symptoms caused by soilborne pathogens such as the wilt pathogens (Fusarium and Verticillium), Sclerotinia, and Pythium. Fusarium and Verticillium do not cause rot on the fine roots or crown. However, they always cause characteristic vascular discoloration in the taproot and crown of the plant. Distinguishing these two pathogens without a laboratory evaluation is not advised, but in general, Fusarium occurs earlier in the crop cycle and often causes a red-to-brown discoloration internally along the taproot and at the base of the crown. Symptoms of Verticillium on the above ground parts of head lettuce become obvious close to harvest; the taproot and crown tissue of infected plants have dark brown-to-black discolorations. Plants with INSV can also be infected with Sclerotinia (S. minor) which is recognized by the characteristic rotting of the crown tissue of the plant and the presence of white, cottony growth and small blacksclerotia (Photo 3). Plants infected with Sclerotinia easily break off at the soil line when you gently tug on them. However, if the plants do not break off at the soil line and do not show any rot on the crown tissue but do exhibit rot on the fine feeder roots or lower down on the taproot, then Pythium wilt is suspected and can be verified by laboratory evaluation.

    Biology and Symptoms of Pythium

    Pythium wilt is caused by the water mold, Pythium uncinulatum. It infects lettuce roots with swimming spores (zoospores) that move to the roots within the water film in the soil. Additionally, it produces a second type of spore (oospore) that allows the pathogen to survive in the soil in the absence of a host plant. Previous studies have reported P. uncinulatum is almost exclusively a pathogen of lettuce and does not cause disease on other vegetable crops. However, it remains unknown whether other crops may contribute to a build-up of the pathogen in the soil. Affected plants will exhibit rotting of the fine and tap roots (Photo 4) and frequently dark discoloration of the inner core of the main root (Photo 5). Symptoms of the above ground parts of the plant include stunting, yellowing, and wilting of the outer leaves and eventual death (Photo 6). Sometimes the plants have a characteristic look where the younger leaves remain upright, but the older leaves are totally wilted down to the soil (Photo 7). This year, we frequently observed fields where plants are infected with Pythium wilt but are also infected with INSV. These mixed infections are confusing and make it more difficult to distinguish what is the cause of the damage. In our experience to date, plants that show foliar symptoms of INSV and that have wilting older leaves are typically infected with both INSV and, in many cases, Pythium wilt. It should be mentioned that we have also observed plants infected with INSV as well as Fusarium.

    The distribution of Pythium wilt in a lettuce field can be variable. Earlier in the summer, fields with this disease typically were infected along the upper or lower ends of the field indicating that the disease may be responding to irrigation or drainage issues. It is possible that there may be a difference in the level of infection between sprinkler and drip irrigated fields, but we cannot say anything definitive at this time. The disease has been found from King City to Castroville. There is a significant difference in the susceptibility of varieties. In fields with multiple leaf type lettuce, we have observed significant differences in susceptibility among varieties with red types being less susceptible (Photo 8). Recently, there have been severe losses in some fields. It is not clear as of this writing, but it is possible that the incidences occurred in response to the heat spells. It is likely that diseased plants were not able to withstand the weather stress due to damaged roots or that extra water applied to address the heat may have stimulated the development of Pythium wilt. Another observation we have made is that at times Pythium mostly infects the fine roots higher up on the root system and in other situations it is more severe at the bottom of the taproot (Photo 9) which may indicate disease initiated farther down on the root system. Given that the disease needs a period of soil saturation for the swimming spores to travel to the roots, issues with soil preparation, drainage and irrigation management may affect the severity of the disease.

    Research Efforts

    Daniel Hasegawa is conducting research on the epidemiology and spread of thrips and INSV. JP Dundore Arias is working on a project with the California Leafy Greens Research Board monitoring the occurrence of Pythium wilt in the Salinas Valley. He is also characterizing isolates of this disease to better understand the organism and will be conducting preliminary evaluations of the sensitivity of the organism to fungicides. Given the rapid onset of severe damage of Pythium and the continued severity of INSV, we are trying to better understand these diseases and how they may interact. We are interested in receiving samples of Pythium wilt. Please contact Richard (rifsmith@ucdavis.edu) or JP (jdundorearias@csumb.edu) to submit samples.

  • Merced Dairy Farmer Donates Easement to Mitigate for School Building

    The California Farmland Trust (CFT) is pleased to share that another property in Merced County has been permanently protected. Simon and Christine Vander Woude, have donated a conservation easement on their property in Merced. The Vander Woude’s nearly 65-acre parcel of farmland is currently planted in field crops for their dairy operation and will forever remain in agriculture.

    “I served on the building committee for the development of Stone Ridge Christian High School,” shared Simon Vander Woude. “The school is a project we were very passionate about. When it was determined that the school would need to mitigate for the land they were building on, I was pleased that we had a parcel that could be utilized for such purposes. Given our interest in the school, we were happy to donate the value of the easement and know that the land would forever be protected,” Vander Woude added.

    The property, located on the westside of Merced, met the mitigation requirement as defined by Merced County, and that’s where CFT stepped in. As a land trust focused on farmland, CFT worked with the Vander Woude’s and the school, to ensure this property would be protected and monitored forever. The agricultural conservation easement (ACE) complimented the Vander Woude’s other sustainability efforts, which include a solar field, as well as other efficient and regenerative water and farm management practices.

    “No two easement projects are the same, but this is unique because Simon and Christine felt so strongly about donating the value of the easement to help the school fulfill the mitigation requirement. Foregoing compensation for the development rights isn’t an easy choice, but we commend their decision,” said Charlotte Mitchell CFT Executive Director.

    The Vander Woude property compliments the existing 34 easements and more than 11,000 acres, that CFT has worked with landowners to permanently protect in Merced County.

    The California Farmland Trust is a California Non-Profit 501(c)(3). Our mission is to help farmers protect the best farmland in the world. To date, we have protected 16,708 acres of farmland on 77 family farms. To learn more visit us: www.cafarmtrust.org.

  • CA Raisin Crop Update & Wildfire Impact

    With smoke-filled skies and ongoing wildfires in forested areas, one may wonder just how the California raisin industry may be impacted by all this.  As harvest continues through the pandemic year, what should we expect from the 2020 crop?  Watch this brief interview with Rick Stark from Sun-Maid growers to find out and read more about it in American Vineyard Magazine.

    Please thank this video’s sponsor Suterra for their industry support.

  • Wine Industry Affected by Wildfires Seeks Extension of Disaster Payment Program

    With growers and winemakers facing unprecedented losses from the devastating West Coast wildfires, leaders of 10 wine industry groups are seeking help from Congress to obtain immediate disaster relief.

    Specifically, they are requesting an extension of the Wildfire and Hurricane Indemnity Program Plus (WHIP+) to cover 2020 wildfire-related losses. Administered by the U.S. Department of Agriculture, WHIP+ provides disaster payments to producers to offset losses from wildfires, hurricanes and other qualifying natural disasters. In 2019, California growers received WHIP+ payments for 2018 covered crop losses due to wildfires, as well as quality losses due to smoke exposure.

    “Farmers are resilient and they accept the many risks inherent to agriculture, but 2020 has produced more challenges than any could have ever anticipated. It’s absolutely essential that Congress extends disaster assistance to California winegrape growers,” said California Association of Winegrape Growers (CAWG) President John Aguirre.

    A jointly signed letter was recently to Congressional leaders by the 10 organizations, including CAWG, California Farm Bureau Federation, Oregon Wine Board, Oregon Winegrowers Association, Oregon Farm Bureau, Washington Winegrowers, Washington Farm Bureau, WineAmerica, Wine Institute and Winegrape Growers of America.

  • Report Provides Data on New Almond Varieties

    Almond Board of California—Innovation always has been part of the almond industry. That includes exciting research about new almond varieties intended to meet the changing needs of consumers, end buyers and fast-growing export markets.

    There are about 70 different varieties of almonds grown around the world. California orchards produce about 30 varieties, though 13 of them – with Nonpareil dominating – account for 98% of what is regularly grown. While other countries may grow multiple other varieties, when it comes to total production California remains on top, producing more than 80% of the world’s almonds and supplying millions of pounds annually to more than 90 export markets.

    Still, California growers and handlers must continue to adapt to provide almonds that satisfy shifting consumer appetites, end-buyer demands and other market forces. What a confectionery business or chocolatier wants in an almond can vary greatly from what someone snacking in India or China wants, which can differ largely from what a company producing almond milk in the U.S. wants.

    The diverse uses for almonds and ever-changing preferences continue to influence demand for specific kernel characteristics such as flavor, appearance, shape, texture and color. Similarly, to continue improving not only what we grow but how we grow, the industry is looking into almond varieties that check horticultural boxes, including the ability to produce more pounds per light intercepted and self-compatibility.

    Recognizing the need to constantly innovate and maintain high demand for California almonds, the Almond Board of California (ABC) began funding almond variety development research in the early 1970s and expanded that effort in the late 1980s to include rootstock breeding. Over the past 20 years, this research has delivered five new University of California (UC) varieties – Padre, Sonora, Kester, Winters and Sweetheart – and supported testing of most commercial varieties and rootstocks for overall performance, resistance to pests, diseases and abiotic stresses. The research has kept California on the cutting edge of almond production globally.

    Now, for the first time, decades of data and results from ABC’s first-ever Crack Out Day (an event held last November at which industry members tasted and compared more than 60 almond varieties from around the globe) have been pulled together in a comprehensive breeding report. For growers looking to replant their orchards as well as nurseries and private breeders, the report offers critical information about the performance and potential promise of different almond varieties.

    “The California almond industry is always looking for better and more sustainable almond varieties,” said Sebastian Saa, ABC’s associate director of Agricultural Research. “We’re convinced that through research and innovation, we’ll find varieties that produce not only more pounds of almonds, but also higher quality with reduced management costs and horticultural inputs in terms of water use, pest management and more. As technology and experience advance, it will allow us to discover better, more efficient varieties.”

    Saa listed the following as some of the key takeaways and learnings provided by the report:

    • The growing number of self-compatible varieties being developed globally.
    • Spanish varieties are mostly hard shell, but some new selections are soft shell and should be evaluated in California.
    •  Spanish breeding programs have mastered late-bloom varieties and self-compatibility traits.
    • The Australian breeding program has some varieties that scored very high during Crack-Out Day and should be evaluated in California.
    • Several varieties created by the U.S. Department of Agriculture and UC breeding programs are performing quite well in ongoing trials in California.

    ‘Diversification is key’

    Breeding is an art of balancing improvements while accepting some trade-offs. To define this balance, experts must consider the various segments of the almond industry, starting with the growers, moving to the hullers and shellers, handlers, food companies and then, ultimately, the consumer. As Saa said, “Diversification is key.”

    “Different uses and different needs demand different varieties,” he explained. “When you think about an almond variety for snacking, for example, you think about crunch and strong flavor. But when you think about a variety for almond milk, you’re probably thinking about milder flavors. And if you’re looking for a variety to cover in chocolate, you’re looking for a short but round kernel shape.”

    Nonpareil and other soft-shell varieties dominate the snack segment because of their shape, smooth surface and light blonde color. Mission varieties like Marcona, Butte, Padre and Fritz typically are used for natural roasted and bulk purposes, as well as in candy and chocolate applications. And California varieties like Carmel, Monterey and Wood Colony often are roasted, salted and flavored. They also are good for slicing and slivering.

    Key varietal differences covered in the report include a summary of how many popular almonds grown in California are auto-incompatible, meaning they require cross-pollination between different varieties, and yet how some of the new varieties are self-compatible, requiring no cross-pollination. Another horticultural distinction covered in the report is crack-out percentage and double percentage. California varieties and some Australian varieties have a high crack-out percentage (kernel-to-shell ratio). In addition, the report discusses different varieties’ tendency to produce kernel “doubles,” and finally, maturity rate and its impact on harvest timing is also mentioned. Armed with this knowledge, said Saa, growers can be more flexible and have more operational diversification.

    “If you have only one variety that you need to harvest within a narrow window, you put a lot of demand on your resources at one critical point in time. However, when you have multiple varieties that you can harvest sequentially, you can leverage your equipment and maximize your resources,” Saa said. 

    Looking ahead to the future of breeding

    Creating new almond varieties is a slow and complex process. It can take as long as 15 years to develop a new breed and then another 10 to 15 years to truly test it.

    “Once you develop a variety, you need to see how it performs under differing weather and environmental conditions — and there’s only one harvest per year,” Saa said. “So in order to be confident in a new variety, we need to test during multiple harvests across the valley. Today, we’re trying to do that more efficiently than ever before.”

    To provide a mechanism to evaluate new varieties across the diverse almond-growing regions in the state, the Almond Board began funding long-term and multi-locational Regional Varietal Trials (RVTs) almost 50 years ago. The first trial ran from 1974-1981 and the second from 1993-2006.

    The current RVT – involving orchards in Butte, Stanislaus and Madera counties, all planted with 30 identical varieties – began in 2014. Saa expects the study to last until 2025. ABC coordinates with the UC’s research system on the RVT, and the UC provides important contributions from the leading plant nurseries and private breeders in the state.

    Saa said some important characteristics that researchers will evaluate in RVTs moving forward include:

    • a bloom period that begins no earlier than Nonpareil,
    • self-compatibility,
    • crack-out percentage equal to or more than 40%,
    • percentage of kernel “doubles” equal to or less than 10%, and 
    • increased yield potential.

    Growers interested in ABC’s RVT are encouraged to check out UC Davis’ Fruit & Nut Research & Information Center, as updated information from the ongoing RVT is expected to be published on the center’s website in early 2021.

  • Opportunities for US Pecans in Taiwan Snacking Industry

    Taiwan pecan imports rose by 74 percent (by volume) in 2019, making Taiwan the second largest Asian market for U.S. shelled pecan exports. Though the number is still small, the Taipei ATO believes there is strong room for pecans to expand in the market, particularly led by the snacking sector.

    Taiwan imports of U.S. tree nuts reached a record high in 2019, amounting to 10,908 metric tons (MT) valued at US$79 million. Across all types of tree nuts, almonds and walnuts consistently account for the majority, holding 47 percent and 35 percent, respectively. Trailing these categories are pistachios (14 percent) and pecans (4 percent), both of which show robust growth from a relatively small base.

    Worthy of attention is the pecan growth, rising by 74 percent to 403 tons, making Taiwan the second largest Asian market for U.S. shelled pecan exports. Though the number is still small, the Taipei ATO believes there is strong room for pecans to expand in the market.

    Taiwan Imports of U.S. Pecans (Unit: ton, US$) 

    According to the trade, the sharp growth in pecan exports is credited to its more competitive pricing in 2019 and the strong demand from the snack manufacturers, coupled with diverted shipments caused by Chinese’s sudden tariff increase. Note that 80 percent of tree nuts in Taiwan are used in food processing, such as roasted tree nut snacks or tree nut powder drinks for breakfast meals. Pecans is no exception to this rule of thumb. Unlike other market’s versatile uses of pecans in the bakery sector, Taiwan bakers tend to use pecans for decoration purposes only. The high pricing pushes bakers away from using pecans, while walnuts are instead substituted. In terms of product specifications, either food processing or bakery sector demand for “halves,” as they consider “whole kernel” appearance is a way to differentiate pecans from walnuts. The most commonly imported pecan format are shelled fancy mammoth and shelled junior mammoth.

    The future demand growth for pecans relies on a long-term coherent education program targeting users and consumers. Although more and more consumers consider pecans as a health food full of good fats and fiber, they are not familiar with its distinctive flavors and uses in cooking. Even in Chinese, the different translations between walnuts and pecans are often unclear or inconsistent. Consistent widespread sampling and education can convey product uniqueness and bridge the pricing barrier. — By Katherine Lee, USDA Foreign Agricultural Service

  • US Tree Nuts Dominate EU Market, Consumer Demand Surges

    In 2019, U.S. shipments of tree nuts to the EU-28 (EU-27+UK) reached $3.1 billion. The United States continues to be the largest supplier of tree nuts to Europe. While EU investment and production of tree nuts continue to increase, production is still far from meeting domestic demand. Confinement measures during the height of the COVID-19 pandemic changed EU consumer habits. As consumers spent more time at home, demand for tree nuts, as a healthy snack option and as a home baking ingredient, grew compared to previous years. The evolution of consumer demand in the fall, the annual peak for tree nut consumption, will determine the extent to which this new consumption level will remain in the long term. 

    Executive Summary

    The EU Market: A Key Trading Partner for U.S. Tree Nuts

    The European Union-28 (EU-27+UK) is the largest export market for U.S. tree nuts absorbing 34 percent of total U.S. tree nuts exports in 2019. East Asia followed importing 23 percent while the Middle East imported 13 percent.

    In 2019, U.S. shipments of tree nuts to the EU-28 reached $3.1 billion. Sales of U.S. almonds (both in- shell and shelled) totaled close to $1.8 billion, followed by pistachios with $609 million and walnuts with almost $328 million. Within the EU, the most significant importers of U.S. tree nuts (in order of importance) are Spain, Germany, and the Netherlands, accounting for 64 percent of total imports.

    The United States continues to be the largest supplier of tree nuts to Europe, with 41 percent of the market share (in value) in 2019. Turkey ranks second with a market share of 20 percent, followed by Vietnam, Chile, and China. Almonds continue to be the main imported tree nut with almost 24 percent of the total EU tree nuts imports. These numbers prove the importance of the United States as an agricultural trading partner to the EU.

    The Food Processing and the Snack Industry Remain the Most Significant Buyers

    The growing popularity of healthier snacking and eating habits among European consumers continues to encourage consumption of nuts, both tree nuts and ground nuts. The fight against cardiovascular diseases, the desire for general health and wellbeing, along with the publication of scientific studies highlighting the benefits of nut consumption, are likely to continue fueling demand for these products.

    In addition, the European food processing and snack industry are the largest users of tree nuts both as an ingredient (for traditional sweets and pastries), and for re-processing and re-export to third countries. Almonds are mainly used as an ingredient for the manufacturing of marzipan, nougat, turron (a Spanish traditional Christmas confection), and many other pastries and sweets. European food manufacturers also use walnuts and pistachio nuts as an ingredient for manufacturing ice cream and confectionaryproducts.

    The snacking industry is channeling its efforts to offer consumers new products and new ways to consume nuts. Thus, due to the mature nature of the European market, EU manufacturers are focusing their strategies on launching new value-added innovative products rather than focusing on volume sales. They continue to emphasize the health benefits of tree nuts, both through advertising campaigns and in packaging.

    Confinement measures in response to the COVID-19 pandemic slightly changed EU consumer habits. As consumers spent more time at home, traditional consumers increased their demand for tree nuts, as a healthy snack option but also as a home baking ingredient. In addition, a wave of new consumers also fueled the growth in household tree nut demand. With the end of confinement measures, it is reasonable to assume that some of these new consumers will continue purchasing tree nuts. The evolution of demand in the fall, the traditional annual peak for tree nut consumption, will also determine the extent to which this new consumption level will remain in the long term.

    Expanding business in the EU market

    Since the EU remains a key export market for U.S. tree nuts, exporters continue to explore ways to expand their overseas business. Trade shows are an excellent opportunity to get to know the market and to meet potential importers. Some of Europe’s leading trade shows are:

    U.S. Cooperators Active in the EU Market

    Trade associations like the Almond Board of California, American Pistachio Growers and the California Walnut Commission continue to develop strategies for the EU market. These trade associations, in cooperation with FAS offices, work actively to further develop the market for U.S. tree nuts. 

    Almonds, Shelled Basis

    Production

    The European Union is one of the world’s leading producers and consumers of almonds. Furthermore, the EU is the single largest export market for California almonds with Spain as the leading European importer. Every year, California almond production is exported to more than 100 countries worldwide, and the EU-28 represents almons 40 percent of all California’s almond exports.

    Spanish almond production continues its upward trend. Currently, high almond prices are increasing the number of hectares dedicated to almond planting as an alternative to less profitable crops. In recent seasons, new almond varieties, more modern irrigation techniques, and good prices have made the almond crop more profitable for investors and improved industry expectations.

    For MY 2020/21, the latest official forecast published by the Ministry of Agriculture, Fisheries and Food (MAPA) estimates a production of 108,303 MT (shelled basis). This preliminary figure denotes an increase close to 8 percent compared to previous year’s crop due to favorable weather conditions during the flowering, lack of significant frosts and above average levels of rain in the winter and the beginning of the spring, in addition to the new production areas with integrated irrigation systems.

    Italy is the second largest EU-28 almond producer after Spain. Sicily and Puglia are the main almond- producing areas, collectively accounting for approximately 88 percent of total supply. Tuono, Pizzuta d’Avola, Fascionello, Filippo Ceo, Fragiulio Grande, Genco, Falsa Barese, Ferragnés are the leading varieties grown in the country. Italy’s marketing year (MY) 2020/21 almond production is forecast to significantly drop from the previous season as reduced volumes in Puglia (due to heavy frosts occurred at the end of March) were not compensated by increased quantities in Sicily. Quality is expected to be excellent in Puglia and good in Sicily.

    Table 1. Major EU Almond Producers by Volume in MT (Shelled Basis)

    Consumption

    Nuts consumption continue to grow, since they are considered a great alternative to healthy snacking. Due to the increasing awareness of healthy lifestyles, nuts are becoming increasingly popular all- around Europe. Nutritionists have included nuts in diets for weight control or the recommended consumption for pregnant women are just examples of benefits, supported scientific studies, which continue to encourage the consumption of nuts, both as snack and as ingredient.

    In addition, almonds represent an important component of the Mediterranean diet. In-shell almonds are mainly sold for fresh consumption. Shelled almonds are milled and generally used as a raw material for confectionary and bakery food companies. New eating habits are also affecting the demand for nuts. The increasing number of plant-based diets is also helping to drive demand for nuts, as consumers look for alternative forms of protein to meat and fish.

    Tree nuts imports are indispensable for EU consumers. Traditionally, consumers prefer locally grown products mainly due to consumer loyalty and habits, but in the EU, consumption of nuts is higher than production; this has caused an increase in both domestic production and in imports of nuts.

    Trade

    Imports

    In MY 2018/19, the United States was the main almond supplier for European importers. U.S. almonds face competition from Australia and locally grown almonds, mainly from Spain.

    By volume, the main EU destinations for U.S. almonds were Spain, Germany, and the Netherlands. Many countries import large quantities of almonds destined both for domestic consumption and re- export markets, as well as for the food and snack industry.

    Table 2. EU-28 Imports of Almonds by Origin in MT (Shelled Basis) 

    Exports

    The top destinations for EU-28 almonds in MY 2018/19 were the United States, the autonomous city of Ceuta and Switzerland. The largest EU almond exporter is Spain with Spanish exports destined mainly for other EU Member States.

    Table 3. EU-28 Exports of Almonds by Destination in MT (Shelled Basis)

    Walnuts, In-shell Basis

    Production

    The two main producing areas in France are:

    -Aquitaine in the South West (including “noix du Perigord” AOC)

    -Rhone-Alpes in the East (including “noix de Grenoble” AOC)

    In 2019, French walnut production decreased especially in the Grenoble area (with a drop of 35 percent). The sharp drop was the combined result of drought conditions in the summer, strong winds that caused fruits to fall prior to harvest, and heavy snow falls that broke many nut-bearing trees right before harvest. In the South West, the crop was slightly better than average. In 2020, total French production is expected to increase compared to last year. In South Eastern France (Rhone-Alpes), 2020 production is expected to increase slightly after the losses in 2019. In the South West, production is expected to be below average because of the drought and hot temperatures during the summer.

    Meanwhile, Romania’s estimated production for 2020 is lower that the last two years due to unfavorable rainfall.

    In Spain, the main walnut growing regions are Andalucia, Extremadura, Castilla-La Mancha, and the Valencia region. As of the date of this report, the Spanish Ministry of Agriculture, Fisheries and Food (MAPA) has not yet published the official walnut production data for MY2020/21. If weather conditions remain favorable, Post expects a slightly higher production of 15,500 MT for the current MY. Read the rest of the USDA Foreign Agricultural Service Report HERE.

  • Growers who Contact PG&E Before Planting can Prevent Loss of Trees – and Lives

    When orchard trees meet power lines, disaster can result. Whether it’s a power outage affecting millions or the accidental death of a line worker, such scenarios can have devastating and far-reaching consequences:

    Ø  In 2003, sagging power lines contacted untrimmed walnut trees in Ohio and caused a massive cascading outage – costing millions and leaving entire cities without power throughout parts of the Northeastern and Midwestern United States, and the Canadian province of Ontario. The incident left millions without power – and came at a great cost to state coffers.

    Ø  In Fresno several years ago, a grower used a boom lift to prune his orchard. When wires from the power line became entangled in the lift, he was electrocuted.

    Ø  In another California orchard, a fast-growing nut tree grounded to a high-voltage power line, causing widespread chaos and power loss throughout the region.

    Unfortunately, these events are far too common. The good news? When Pacific Gas and Electric Company (PG&E) and growers work together, we can prevent these losses and tragedies.

    Growers need only contact PG&E at 1-800743-5000 or at planbeforeplanting@pge.com early in their planning phase – before they plant new trees. One call or email is all it takes to eliminate the risk of tree removal and gain some valuable peace of mind.

    PG&E also offers a Mature Orchard Incentive Program for Transmission Lines, which encourages orchard growers to remove nut-bearing trees under transmission lines. Growers can use the incentive to replant crops that are compatible with electric transmission lines or reinvest the funds according to their needs. 

    Public Safety, our Priority

    As a utility provider, our most important responsibility is to ensure public safety and provide a reliable supply of electricity. To meet those obligations and state and federal regulations, we must maintain safety clearances between trees and other vegetation and our high-voltage power lines.

    The electrical charge carried by high-voltage lines is many times more powerful than the current that flows through standard power lines. Naturally, the potential for life-threatening injuries is commensurate with that power.

    For those reasons, we take great care to regularly inspect our transmission lines for potential hazards, using ground patrols as well as aerial remote sensing.

    Each year, PG&E is required to inspect all electric transmission and distribution lines across our 70,000-square mile service area. Our inspections are audited, and we will be fined if we fail to comply with required standards for vegetation clearance.

    Multiple Risks at Play
    Electricity from power lines finds its way to the ground using nearby objects. Like lightning, it can jump to a building, a person or a tall tree. Electrical storms and lightning strikes can also lead to a voltage surge, which may create an electrical arc that travels to nearby objects like trees, vegetation and people.

    When trees or vegetation are located near high-voltage power lines, they pose serious fire and electrical hazards. Anyone on the ground is at risk – whether they are in contact with the power line or just standing near the tree.

    And when a tree trimmer or a child climbs or shakes that tree – or when the tree contacts a power line – the risk to lives and property is multiplied, often with tragic consequences.

    Reasons for Generous Clearance
    We understand that growers need to plant every possible acre, and that some consider our clearance requirements excessive. But our requirements are based on many decades of field experience – and the fact that a variety of conditions can create dramatic material changes in towers and power lines.

    High-voltage power lines also require more clearance than other power lines because of their current strength and potential hazards. In addition, clearance requirements must account for the real possibility of line sag, which depends on weather, line design and electrical load.

    Metal transmission conductors can expand in hot conditions, sometimes causing wires to sag. Wind and ice storms can also wreak havoc, loosening normally taut wires and causing branches or trees to fall into electrical lines.

    During hot weather, power lines carrying heavy electrical loads can become heated, causing them to stretch out. These elongated lines can sag near the ground or near trees and other objects.

    As a result, what appears to be generous clearance in winter months may not be enough in the heat of summer.

    Tree Growth Exceeds Expectations
    Our mantra – “plan before you plant” – is not a new message. Yet it isn’t accepted by some growers, despite its potential to benefit their operation and their community.

    Some growers question whether their young trees could ever interfere with power lines that soar 40 or 50 feet – especially when tree purveyors provide assurance that their stock will top out at 20 or 25 feet.

    But plantings routinely exceed their expected growth rate and height. We’ve experienced trees that have grown 12 feet in a single growing season.

    Other growers fail to notify PG&E because they misunderstand the nature of our easement on their property. They may believe the electric easement right-of-way for vegetation applies only to our wires in the air, when it actually extends across a grower’s physical property.

    It’s also human nature to hope for the best – or to think “it can’t happen to me.” In fact, one of the state’s largest nut producers learned through trial and error that power lines and orchard trees don’t mix. Today, he contacts us regularly before planting.

    Every orchard is vital to the economic health of our state. By working together, we can prevent injuries and power outages, and preserve more trees.

    Contact PG&E at 1-800-743-5000 or at planbeforeplanting@pge.com so we can identify power-line friendly planting locations that avoid transmission lines. We’ll be out to your orchard within days, at no cost to you. — By John Bolling, Orchard Vegetation Program Manager, PG&E

  • Rural Energy for America Program Grant

    The Propane Education & Research Council encourages producers to apply for the United States Department of Ag (USDA) Rural Energy for America Program (REAP) Grant, which offers funding for renewable energy systems or to make energy efficiency improvements. Through the program, producers or small business owners can receive a 25 percent grant for replacing a diesel irrigation engine with a propane-powered engine.

    The USDA REAP recently announced Nov. 2 as its fall deadline for the Renewable Energy systems and Energy Efficiency Improvement Grant, so PERC encourages interested applicants to act quickly to save even more on propane-powered engines.

    “With lower purchase costs and savings of up to 50 percent compared to diesel engines doing the same job, farmers are already saving big by switching to propane irrigation engines,” said Michael Newland, director of agriculture business development at PERC. “For anyone considering making these energy efficiency upgrades to their operation, now is the time to act and take advantage of additional savings with the USDA REAP program.”

    Funds can be used for the purchase and installation of a new propane-powered irrigation engine, and any agricultural producer who makes over 50 percent of gross income from agriculture is eligible to apply. The grant is good for up to 25 percent of the total upgrade cost, with a $1,500 minimum and $250,000 maximum.

    “There’s never been a better time to replace a diesel irrigation engine with a cleaner, more cost-effective propane alternative,” said Newland. “On top of cost savings, propane engines help meet strict emissions goals and can keep your ag operation running no matter where you live or what happens with the electric grid.”

    Grant applications will be accepted at local USDA offices through Nov. 2. Find your nearest USDA office, andget full program details.

  • Why Aren’t My Beans Drying Down?

    We cut our blackeye bean (cowpea) research plots at UC Davis almost 3 weeks ago and they’re still too green to harvest. If we tried now, the vines would get wrapped around the threshing cylinder.  Several growers in the Sacramento Valley have mentioned that their corn has sat at the same moisture level for weeks and is not drying down either, as one would normally expect for this time of year. But, nothing is normal this year!

    Why aren’t our crops drying down?

    Tragic fires throughout the West have pushed a lot of smoke and ash into the sky, creating fog-like conditions that reduce the intensity of the sun, shade crops, and lower temperatures. The blanket of smoke is like stepping into the shade under an awning on a 90oF day. This reduced sun intensity has affected the ability of crops to dry down in a timely manner. Increased humidity levels this past weeks haven’t helped either.

    While shading may be good for protecting tomatoes from sunburn with harvests running late due to COVID-related challenges, it is not good for drying down field crops.

    With the smoke finally dissipating, drying conditions are improving. We ended up turning our blackeye bean crop over to increase aeration and help it dry down.  Dry beans are sometimes turned to help dry the crop down, especially if they’re rained on, but the challenge is to be careful to prevent shattering.

    In corn, there aren’t any easy solutions.  One grower said their corn sat at 16.5% moisture for several weeks and finally they had to harvest it anyway. Dryers are available for drying corn and other crops to the proper storage moisture, but as we all know it’s expensive and with low grain prices this affects the bottom line.  — By Sarah Light & Rachael Freeman Long, UC Cooperative Extension
