Threecornered alfalfa hopper infestations are a yearly occurrence in soybeans grown in Virginia’s piedmont region, causing economic damage. This research takes the first steps to characterize infestation timing, yield-damaging potential, insecticide control plans and cultural control strategies for this poorly understood pest. On-farm research determines if economical control with insecticides (seed and foliar) can be achieved and if losses can be offset with other cultural practices (e.g., seeding rate); develops better understanding of the insect’s dependence on environment, cropping system and neighboring land use on the insect development, infestation level, and timing of infestation; and develops better scouting methods. Key Benefactors: farmers, agronomists, extension agents
Data summaries with a brief discussion of progress and results will be compiled and updated weekly throughout the growing season and made available to growers and others in the Ag sector via the Virginia Ag Pest and Crop Advisory.
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.
