ND SECTION 18 FOR SPARTAN IN FLAX

The U.S. Environmental Protection Agency has issued a Section 18 specific exemption for Spartan 4F, allowing North Dakota flax producers to use the herbicide to control kochia and ALS resistant kochia.

The exemption allows a single ground application of 3 to 8 fluid ounces of Spartan 4F per acre, depending on soil type. The application must be made up to 30 days before and three days after planting.

Applicators must follow all directions, restrictions and precautions on both the Section 18 use directions and the EPA registered product label. They must have a copy of the Section 18 use directions in their possession during application.

Users of Spartan 4F under this exemption are required to comply with both the full product labeling and the exemption use directions. Copies of the exemption use directions can be obtained from the ND DOA homepage (http://www.agdepartment.com/Programs/Plant/Section18Exemptions.html) or from the homepage of the NDSU Pesticide Training and Certification Program (http://www.ag.ndsu.nodak.edu/aginfo/pesticid/pesticid.htm).

A special thanks goes out to Dr. Brian Jenks the North Central Research Extension Center for this one. If you recall, we did not have this exemption available in 2007 due to a lack of data to the economic loss arguments for the pest situation being an emergency. Brian initiated field experiments last year to fill these data gaps, and results from these experiments were critical to make our case and complete the Section 18 exemption request document this year.
