Insecticides for Control of Spider Mites in Soybeans

Updated April 13, 2007

Economic Threshold:

Iowa State University Extension specialists have suggested that control may be warranted when infested plants have
substantial spotting or leaf yellowing and live mites, but before mites cause browning and leaf drop.
