Requirements for Applicators of Xtendimax, Engenia or Tavium in Ohio:
Take the dicamba-specific training (see below). Training is required annually for certified applicators.
Even if dicamba is just being applied as pre-burndown (not over the top), dicamba-specific training is still required. The label requirement does not make any training exceptions for how/when to use dicamba.
- Five year registration for two over-the-top end-use dicamba products - XtendiMax with VaporGrip Techonology and Engenia Herbicide. The registration for an additional over-the-top dicamba product, Tavium Plus VaporGrip Technology, was extended. These registrations will expire in 2025, and they are only for use on dicamba-tolerant (DT) cotton and soybeans.
- Only certified applicators may apply dicamba over the top (those working under the supervision of a certified applicator may no longer make applications). Get Exam Prep Here
- Prohibit over-the-top application of dicamba on soybeans 45 days after planting and cotton 60 days after planting
- For cotton, limit the number of over-the-top applications from 4 to 2 (soybeans remain at 2 over-the-top applications)
- Applications will be allowed only from 1 hour after sunrise to 2 hours before sunset
- In counties where endangered species may exist, the downwind buffer will remain at 110 feet and there will be a new 57-foot buffer around the other sides of the field (the 110-foot downwind buffer applies to all applications, not just in counties where endangered species may exist)
- Clarify training period for 2019 and beyond, ensuring consistency across all three products
- Enhanced tank clean out instructions for the entire system
- Enhanced label to improve applicator awareness on the impact of low pH’s on the potential volatility of dicamba
- Label clean up and consistency to improve compliance and enforceability
