Brief Project Summary:

The goal of this research project is to protect soybean yields by optimizing productivity and improving pest management strategies. This project will evaluate existing and emerging insect suppression tactics, like insecticides and host plant resistance, to protect yield and develop a suitable management plan. Insecticides will be evaluated and research findings will be communicated to Iowa soybean growers as part of the Extension educational program.

Final Project Results

Weekly aphid scouting started at both locations at the VC-V1 growth stages. Randomly selected plants within each plot were selected and the number of aphids on each plant was recorded. Soybean aphids began to appear in the plots during the last week of June at the Northwest Research farm and during the third week of July at the Northeast Research Farm. Foliar treatments for evaluation were made on 14 August 2014 at the Northwest Research Farm; and were made on 22 August 2014 at the Northeast Research Farm. Peak aphid densities in the control plots were reached on 5 August 2014 at an average of 29 aphids per plant at the Northwest Research Farm, and on 19 August 2014 at an average of 305 aphids per plant at the Northeast Research Farm. Weekly scouting concluded three weeks after aphid densities reached their peak for each farm, at which point soybean aphids were in considerable decline.

Publications-Two publications in ”In Integrated Crop Management News”..

Presentations- Eight presentations at field events at the Field Extension Education Laboratory, Iowa State University, Ames, IA.

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.
