Regional Responses to Dicamba Drift Complaints
July 13, 2017
The Missouri Department of Agriculture (MDA) has issued a temporary Stop Sale, Use or Removal Order on all Dicamba products. All agricultural pesticide users in Missouri, including certified commercial applicators and private applicators, must immediately cease in-crop, post-emergent use of all Dicamba products.
The stop sale order applies to both 'older' formulations and 'newer' formulations, such as Monsanto's Xtendimax, DuPont's FeXapan, and BASF's Engenia. The MDA order states that "upon the department's approval and registration of Special Local Need labels for Xtendimax, Engenia and FeXapan, these three products will be released for sale and use in accordance with the new label restrictions." The MDA order remains in effect until December 1st 2017 for all other Dicamba products.
The University of Missouri (UMC) estimates over 200,000 acres of soybeans have been injured throughout Missouri, with the majority in the bootheel region. UMC sighted off-site movement from drift, nighttime spraying, tank contamination, improper sprayer set up, and other reasons for the injury.
The Kansas Department of Agriculture (KDA) has seen an increase in herbicide misuse complaints alleging crop damage due to herbicide products containing dicamba. KDA’s pesticide and fertilizer program staff are actively investigating these complaints for noncompliance with state and federal laws, but cautions producers that these investigations will not characterize crop damage, acres involved, or estimated dollar losses.
KDA strongly encourages all users of herbicides, including products containing dicamba, to be attentive to label requirements when selecting and applying products (not all dicamba products are labeled for soybean application), to be aware of vegetation on surrounding properties, and to be vigilant of weather conditions. Meticulous cleaning of tanks, hoses, and nozzles used for herbicide applications in necessary to prevent chemical carry over to the next application. Caution is especially important if you have crops in different growth stages, e.g. double cropping soybeans after wheat.
KDA supports the development of new technologies in the agricultural industry, and stands ready to assist the agricultural community as it determines how to implement the new technologies to be more efficient and sustainable in producing the food supply for a growing world. Of note, KDA does not plan to limit use of dicamba in Kansas.
Beginning July 11, 2017, the Arkansas General Assembly's Legislative Council implemented a 120-day emergency ban on Dicamba in that state. During the 120 days, a task force will be convened to discuss potential paths for
