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.
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.
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.
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.
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.
July through August is a good time to check soybean fields for soybean cyst nematodes (SCN), the most devastating pest for soybean growers. Yield losses of 25-30% have been documented in fields with no visible injury on the soybean plants.
