Pre-harvest Intervals for Foliar Fungicides on Wheat

By Daren Mueller, Department of Plant Pathology

EPA has notified the Iowa Department of Agriculture and Land Stewardship that some problems with compliance with pre-harvest intervals for fungicides applied to wheat in Kansas were discovered this year. Some wheat was embargoed until tests could be completed to determine residue levels. Although Iowa has a small number of wheat acres compared with Kansas and other nearby states, pesticide applicators and growers should check the pre-harvest intervals (PHIs) for any wheat fungicides that have been applied.
