Soybean aphid is the major pest of South Dakota soybeans. Spraying fields to control soybean aphids is costly and sometimes causes flare-ups of late-season secondary pests. Planting cultivars of earlier-than-recommended maturity, or planting early, might limit soybean-aphid infestation magnitudes, reduce the need for insecticides, avoid late-season pests such as spider mites, produce respectable yields and a savings for farmers. No reports on the effect of early maturity or early planting against soybean aphid has been published for South Dakota. This project will compare soybean-aphid infestation and yield of early maturity group soybeans to standard maturities over two planting dates as a tactic for managing soybean aphid and reducing insecticide use.Key Benefactors: farmers, agronomists, applicators, ag retailers, extension specialists
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.
