The North Dakota Department of Agriculture has issued a special local needs (SLN) registration to Bayer CropScience, allowing aerial application of Laudis herbicide to control weeds, including kochia, in cornfields.

Wet conditions from above-normal rainfall precipitation may have prevented ground application of herbicides. The state label would allow Laudis to be applied by aerial application. Laudis is federally registered for use on corn, but only for ground application.

The labeling prohibits grazing of livestock or harvesting corn forage in treated fields within 45 days of application. Applicators must follow directions, restrictions, worker protection standard requirements and precautions on the full product label and the SLN labeling. They must also have the SLN labeling in their possession during application.

Section 24(c) of the Federal Insecticide, Fungicide and Rodenticide Act gives states the authority to register additional uses for federally registered pesticide products, or new products to meet special local needs and EPA reviews these registrations.
