$6,000Peanut growers need effective and economic options for thrips management. Our goal was to identify what these options are, both for now and the near future, through unbiased university research, and to provide findings to peanut growers at county production meetings, field days, and through Virginia Cooperative Extension publications and websites.
Results from three 2013 thrips field experiments at the Virginia Tech Tidewater AREC in Suffolk, VA show that certain new peanut seed treatments and liquid in-furrow insecticides, especially when oversprayed with a foliar broadcast insecticide at the late ground-cracking stage for thrips, can achieve the following:
• Reduced adult and immature thrips populations
• Reduced plant injury caused by direct thrips feeding
• Reduced thrips-transmitted incidence of Tomato spotted wilt virus
• Yields similar to conventional (i.e., granular in-furrow) thrips insecticides
