At the US Highbush Blueberry Council’s (USHBC) Innovate 2021 Conference, Markus Kleber, professor of soil system science at Oregon State University, hosted a “Carbon Sequestration Lunch.” The session provided an overview of carbon sequestration and detailed the potential benefits to blueberry growers and farmers everywhere. Kleber explained that, as carbon dioxide (CO2) in the atmosphere increases, CO2 molecules absorb part of the energy from solar radiation, causing more warming in the atmosphere. This, of course, could have significant impacts on blueberry production across the globe. Despite improvements in reducing emissions, there is still a 0.6% annual increase in greenhouse gas (GHG) emissions globally.
“Humans are intervening in the carbon cycle, and industrial agriculture has driven down the carbon in the soil,” Kleber shared. “When you lose half your soil carbon, you’re bound to see reductions in plant productivity…When we talk about carbon sequestration we are referring to the transfer and storage of atmospheric carbon to other pools, such as soil or plant biomass.”
Best management practices can restore at least some of this carbon, and soil carbon sequestration can be a significant GHG removal practice. Despite various challenges, there’s strong public interest in finding carbon sequestration solutions. Growers should recognize and take advantage of this interest, both through marketing and farming practices. Increasing soil carbon can be beneficial for overall soil health.
As part of the 2021-25 strategic plan, USHBC will review global sustainability considerations of relevance to the entire blueberry supply chain and develop an overall approach for how to build these considerations into USHBC’s programs and industry practices.

Blueberry growers across America today established a new coalition, the American Blueberry Growers Alliance, to seek relief from rising imports that are harming their businesses. The Alliance will provide information and support to an ongoing U.S. International Trade Commission (ITC) investigation into the serious injury caused by increased imports of fresh, chilled and frozen blueberries under Section 201 of the Trade Act of 1974.
Several crown, fruit, and foliar diseases cause significant yield losses to strawberry. Gray mold or Botrytis fruit rot caused by Botrytis cinerea, mucor fruit rot by Mucor spp., and Rhizopus fruit rot by Rhizopus spp. are common fungal diseases in California. Botrytis cinerea is more prevalent and damaging fungus among these pathogens warranting regular fungicidal applications. Fungal spores survive in plant debris and soil and infection can occur before flower initiation. Both flowers and fruits are subjected to infection. Severely infected flowers fail to develop into fruits. Infection on developing or ripe fruit occurs as brown lesions, usually under calyxes. Infected areas rot and become dry and leathery under dry conditions or produce a thick, gray mat of spores under cool, moist conditions.
Mucor spp. invade the fruit through ruptured skin and cause leaky fruit rot. Under high humidity, profuse fungal growth of white, tough filaments with black spore-bearing structures is seen covering the fruit. In the case of Rhizopus fruit rot, discolored, water-soaked spots develop on fruit eventually leading to wilting. Similar to the Mucor fruit rot, Rhizopus rot also leads to leaky fruits and development of black spore-bearing structures on white mycelia under high humidity. Both pathogens survive in dead and decaying plant material and can persist in the field.
