North Dakota Agriculture Commissioner Doug Goehring has issued a special local needs (SLN) registration to FMC Corp., enabling North Dakota dry bean producers to use the herbicide Spartan Charge to control kochia, eastern black nightshade and other problem weeds.
"In annual surveys, North Dakota bean growers consistently rank kochia and eastern black nightshade at or near the top of the list of major weed problems," Goehring says. "Since no federally-registered herbicides are available for growers to effectively manage these weeds, I am confident the situation meets the criteria of a special local need."
The SLN registration supplemental labeling allows early pre-plant or pre-emergence application of Spartan Charge to dry bean fields by ground or aerial equipment. Rates vary from 3.75 to 5.75 fluid ounces of product per acre depending on soil texture and percent organic matter.
The labeling prohibits applying more than 7.75 fluid ounces of product per acre per 12-month period. The product may not be used on coarse soils classified as sand with less than 1.5 percent organic matter and a soil pH greater than 7.0.
Users must follow all precautionary statements from the Section 3 label and the supplemental SLN labeling and must have the SLN labeling in their possession during application.
Although this use is fully registered with EPA, the manufacturer has not put the use on its full container labeling due to the potential for crop injury. The supplemental labeling states that the user accepts all risks associated with crop injury.
North Dakota is the nation's leading producer of dry beans, growing 34 percent of the U.S. total in 2009.
