AGRONOMY TALK: COVER CROP TERMINATION

While cover crops provide a variety of benefits, cover crop termination in the spring requires additional management practices. Spring cover crop termination varies by cover crop species, the goals of cover cropping, whether that cover crop will be used in the spring (i.e., forage), weed pressure and species, and the proceeding cash crop.

Agronomy Talk: Frogeye Leaf Spot

Frogeye leaf spot (FLS), caused by the pathogen Cercospora sojina, is a common soybean foliar disease of many soybean-producing regions worldwide. In the U.S., the disease is established in southern production regions and has recently become prevalent in the Midwest and Upper Midwest. It’s believed that the range expansion and increased disease severity are caused by widespread planting of susceptible varieties, warmer winter temperatures, and the increased adoption of conservation tillage practices, which, together, lead to increased inoculum levels. FLS does not always cause yield loss, but yield loss of up to 60% has been reported with severe infection rates.

Agronomy Talk: Yield Components of Corn

Corn grain yield, typically measured in bushels per acre, can be broken down into distinct components that each contribute to the weight of harvested grain. While genetics govern some yield components, much of the harvested yield is directly affected by environmental conditions and management practices. Yield components include number of plants per acre, number of ears per plant, the number of kernels per ear, and the weight of each kernel.

AGRONOMY TALK: EUROPEAN CORN BORER

European corn borer (ECB) (Ostrinia nubilalis [Hubner]) was introduced to the eastern United States in 1917 and quickly became an economically important pest of the Corn Belt. With the introduction of transgenic Bt (Bacillus thuringiensis) corn in 1996, damage from this pest has been mitigated.
