BISMARCK, N.D. (AP) _ North Dakota's agriculture commissioner is allowing aerial application of a herbicide to control weeds in cornfields.
Commissioner Doug Goehring issued a special local needs registration to Bayer CropScience, allowing the aerial application of Laudis herbicide to control kochia, ALS-resistant kochia, and glyphosate-resistant weed species.
Goehring says that state has seen above-normal rainfall this spring, and the wet conditions make it difficult or impossible for ground pesticide application equipment to be used in some fields,
Goehring says Laudis is federally registered for use on corn, but only for ground application.
Officials say the highly adaptable and prolific kochia is one of the most serious weeds problems for North Dakota growers. If uncontrolled, kochia can significantly impact yield of corn and other crops.
