Corn growth simulations across the Corn Belt indicate early corn maturity of one to two weeks for most sites. Simulated corn yields for rainfed and irrigated sites across the region near or above normal at most sites.
Reports of orange gall midge in soybean increased in Nebraska this year and researchers have initiated in-field and laboratory studies to help learn more about its potential to reduce yield as well as best practices for its management.
Nebraska Extension’s Aug. 22 Midwest Soybean Production Clinic and Aug. 23 Midwest Corn Production Clinic will provide in-field opportunities for participants to work with crops in the early vegetative stages of growth through maturity.
Soybean aphid populations can explode in August under favorable conditions. Vigilant scouting is recommended, especially in northeast Nebraska where populations have historically been highest, to allow for timely management decisions.
Recommendations for scouting and managing soybean aphids, including why the 250-aphids-per-plant threshold is used. Two tools―an app and Excel worksheet―can help speed up scouting in the field and indicate when treatment is warranted.
Defoliation injury is being reported in soybeans and often can look worse than it is. This illustrated guide to assessing injury can help you get reliable scouting numbers on which to base sound treatment decisions.
