Dr. Leaf discussed how pesticide regulation works at
the federal and state level. The Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) is federal law that governs how pesticides are
registered, distributed, sold, and used in the U.S (i.e., "the label is
the law"). Pesticide registration is also when tolerance levels are determined for food crops and what label requirements are needed for in-field use to prevent pesticide residues occurring above the maximum residue limit or other safety concerns.
Recently, tolerances of a common insecticide, chlorpyrifos,
were revoked on all food and feed crops by the U.S. Environmental Protection Agency and is no longer permitted for
agricultural use in 2022. Enlist Duo has also undergone label changes
where initially use was not permitted in six MN counties due to
endangered species concerns, but after review, use is now permitted
after determining those species are not present in those counties. Dr. Leaf also gave updates on additional guidance from MDA on dicamba use requirements.
This podcast was hosted by Dr. Anthony Hanson (hans4022@umn.edu), an IPM Educator for Field Crops with University of Minnesota Extension based out of Morris, MN. The purpose of the IPM podcast is to alert Growers, Ag Professionals and Educators about emerging pest concerns on Minnesota field crops. We also review recent pest trends and research updates.
