Spider mite injury is being found in Iowa soybean, but no injury has yet been reported in corn. Some areas, particularly in western Iowa, are under drought stress and these fields also may develop economic infestations of spider mites. If mites do appear, deciding whether to use a pesticide to control the population may be necessary.
