Hopefully, some of you reading this may recall previous articles on recent Environmental Protection Agency revisions to pesticide labels and Worker Protection Standards for farms, nurseries and greenhouse operations regarding respirators.
Newly registered dicamba — Engenia, FeXapan, XtendiMax, and Tavium — and 2,4-D — Enlist Duo and Enlist One — products labeled for in-season, over the top application of Xtend or Enlist cotton and soybean are now registered as restricted use pesticides, meaning only certified or licensed applicators can purchase and legally apply them.
In an effort to reduce damage to sensitive crops from off-site movement of these products, the product label requires that all applicators must attend Auxin Herbicide Best Management Practices Training annually.
North Carolina Cooperative Extension has been tasked with the responsibility of offering this statewide training once again this year. A regional Auxin Herbicide Training will be offered at 4 p.m. on March 4 at the Southeastern N.C. Agriculture Events Center, located at 1027 U.S. 74, Lumberton. You can find a complete list of training opportunities at https://cotton.ces.ncsu.edu/2019/12/2020-schedule-auxin-herbicides-best-management-practices/.
The dicamba products mentioned will require extensive record keeping which applicators must keep on file for two years. In addition to standard restricted use pesticide product record-keeping, applicators also need to record the spray system cleanout procedure used, beginning and ending times, air temperature, wind direction, wind speed, nozzle type and pressure, tank mix products, and date of sensitive crop registry and neighboring field survey. Record-keeping templates can be found at http://www.ncagr.gov/SPCAP/pesticides/auxin.htm.
Another important EPA label revision is for all products containing paraquat-dichloride (paraquat), including but not limited to trade names Gramoxone, Para-SHOT, Parazone, Quick-Quat, Firestorm or Helmquat. New labeling of these products require that any person who intends to use paraquat must be a licensed or certified North Carolina Department of Agriculture and Consumer Services applicator and must successfully complete the new How to Safely Use and Handle Paraquat-Containing Pesticides Training.
“Uses” includes mixing and loading the pesticide, applying the pesticide, and other pesticide-related activities, such as transporting or storing opened pesticide containers, cleaning equipment, and disposing of excess pesticides, pesticide containers, and other paraquat-containing materials.
The paraquat training certificate is not required for purchasing the product, but a Restricted Use Pesticides certificate or pesticide license is required before a purchase can be made from a licensed dealer. Non-certified people working under the supervision of a certified applicator are prohibited from using paraquat, including any of the “use” activities mentioned above.
Once the certified applicator successfully completes the training with a 100% score on the final assessment, a certificate will be automatically generated. Per the new labeling, applicators are required to retain certificates of training completion in their records. The training must be retaken every three years. Training can be completed online at http://www.usparaquattraining.com/ or face-to-face at any approved pesticide training provided by N.C. Cooperative Extension. An in-person training has been scheduled for March 12 at 7 p.m. at the O. P. Owens Agriculture Center, 455 Caton Road, Lumberton.
The EPA is allowing the sale of paraquat that is already in the supply channels that do not have the new labels. Paraquat products with old labeling will not require the new training requirement.
