A new USDA-NIFA funded Outreach Webcast on Soybean Defoliation has been published on the Plant Management Network. This open access webcast is by Dr. Thomas Hunt, Professor and Extension Entomology Specialist at the University of Nebraska, Haskell Agricultural Laboratory, Concord NE.
Defoliation is one of the most readily observed types of insect injury to soybean. A number of different insect species defoliate soybean, and often it is the combined injury of two or more defoliating insects that results in economic damage. This presentation will help consultants, crop scouts, and growers and other practitioners in U.S. soybean-producing states to understand more about insect defoliation and how it can be managed. Specifically in this presentation, practitioners will learn: how insect defoliation is related to yield loss, how to accurately estimate insect defoliation, and how to use general soybean insect defoliation thresholds. By the end of this presentation, practitioners should know more about insect defoliation of soybean and how to use this information to make appropriate soybean insect pest management decisions.
