With soybean aphid infestations, it's important to preserve natural enemies under an integrated pest management approach, as well as treating only when pest populations reach economic or treatment thresholds, to let beneficial insects do their work.
Soybean aphids in Nebraska typically reach the economic threshold and require treatment in late July through August. Treatment during this time is usually enough to keep aphid populations from resurging before they leave fields for the season.
Nebraska Extension will be offering five private pesticide applicator trainings via Zoom in March and April. Each one will have a different agricultural area of focus, including alfalfa, corn, soybean, pasture and wheat.
Confronting Crop Challenges will be the focus of five meetings to be held in northeast Nebraska this December. Each offers updates on recent crop and pest issues in eastern Nebraska as well as pesticide applicator recertification training.
