Summary: This presentation will help consultants, growers, and other practitioners in any region of the U.S. where soybeans are produced to identify, scout, and manage spider mites. Spider mites can pose severe threat to soybeans, especially in drought conditions, and caused significant yield losses to soybean production in the past. Specifically, I present description of morphology and basic biology of the two main spider mites attacking soybeans, and include images of spider mites and their injury to soybeans. I also include specific information on scouting for spider mites, and describe levels of plant injury associated with growing spider mite infestations that warrant pesticide applications. By the end of this presentation, the audience will know how to identify spider mites and plant injury caused by the mites, and will be able to scout for spider mites and make appropriate decisions about pesticide applications.
United Soybean Board (USB) farmer-leaders develop and maintain partnerships with U.S. land grant universities and U.S. ag-focused research organizations such as the Plant Management Network to increase the transfer of checkoff-funded applied and practical production research information to U.S. soybean farmers.
