Brief Project Summary:

The first goal of this research is to continue to monitor soybean aphids for pyrethroid resistance, and determine the efficacy of insecticides towards these pests. Researchers will sample fields in 12 additional counties to evaluate extent of their spread. The second objective is to evaluate the impact that tillage and cover crops have on fungicide, insecticide, and a combination of fungicide and insecticide seed treatments. There is ongoing discussion of their importance for Midwest soybean production. Current management recommendations assume that early season pests are generally not associated with economic injury in soybean fields.

Key Benefactors:
farmers, entomologists, applicators, ag retailers, extension specialists

Information And Results
Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
