The agricultural herbicide dicamba is back on the market in 2019, and with that come some changes that farmers and applicators should note going forward. These dicamba containing products include Engenia® (BASF), FexapanTM (Corteva/DuPont), and Xtendimax® (Bayer/Monsanto). To begin, all agricultural products containing dicamba (even the older ones), are now restricted use pesticides (RUPs), which means you need a license to purchase and apply the product. For the post-emergent products listed above, some new rules are worth highlighting this year, as required by U.S. Environmental Protection Agency (EPA). Note that the Office of Indiana State Chemist (OISC) has not added to the rules required by EPA on the federal pesticide labels.
In Indiana, only fully certified and licensed Private Applicators (farmers) and Commercial Applicators (Category 1) can purchase OR use these products during 2019 and 2020. Registered Technicians and other non-certified applicators working under the supervision of a certified applicator may no longer purchase or use these products. Mixers, loaders, handlers, and spray equipment cleaners also need to be certified applicators in 2019.
Prior to applying these products in the 2019 growing season, and each growing season thereafter, all applicators applying the products must complete dicamba specific training. OISC will refer to this training as MANDATORY DICAMBA TRAINING. In 2019, MANDATORY DICAMBA TRAINING will be conducted by product manufacturers. In Indiana, the Office of Indiana State Chemist has indicated that farmers involved with a drift complaint will have their permit suspended for five years if they use these dicamba products and do not have the annual training. This means that that person would be unable to purchase restricted-use pesticides.
Please stay tuned or reach out to product reps in regards to where and when these trainings will be scheduled. Farmers and applicators will receive a full list of label changes once they attend a training session. For reference, I would encourage visiting the dicamba portion of the OISC website found at: https://www.oisc.purdue.edu/pesticide/dicamba.html, which includes a helpful frequently asked questions document.
I would also recommend checking out the Purdue Extension publication PPP-119, Engenia, Xtendimax, and Fexapan Application Quick Guide and Required Records for Applications (publication date 12-12-2018). If you got a copy of this pictograph and blank record last year, it has changed to reflect new national label language so find a current copy at www.edustore.purdue.edu.
