Minor spider mite injury is being found in scattered locations across Iowa in soybeans, but no injury has yet been reported in corn. Some areas, particularly in northwestern Iowa, are under drought stress and these fields also may develop economic infestations of spider mites. If mites do appear, a miticide may be necessary to control the population.
