It’s that time again. As Illinois farmers approach spring planting season, focus will again turn to fieldwork and soon, weed management. Dicamba is a powerful and complex tool in the weed management toolbox.
The 2020 soybean crop series on dicamba usage continues with more information regarding the federal label as well as available training sessions – a requirement each year for applicators.
Although the bulk of this series focuses on the Illinois Special Local Needs Labels, applicators should always review the full underlying federal label of the product they intend to use.
Products include Engenia (BASF), XtendiMax (Bayer), FeXapan (DuPont) and Tavium (Syngenta).
In reviewing the federal label, there are a few points to highlight for applicators:
- Only certified applicators may apply dicamba over the top (those working under the supervision of a certified applicator may no longer make 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 57-foot buffer around all other sides of the field to protect sensitive areas (the 110-foot downwind buffer applies to all applications, not just in counties where endangered species may exist).
The label changes made by the U.S. Environmental Protection Agency in October 2018 included a revision that required annual dicamba-specific training.
Dicamba-specific training is required prior to applying these products in the 2020 growing season.
This training must be completed each year, so those who received the training in 2019 must have the training again in 2020. There is no carry-over in training qualifications from year to year.
Training has been offered by representatives of the four registrants via in-person classroom settings and online for the past several months.
At this time, in-person classroom training sessions are no longer available as a precaution against the spread of COVID-19. Any of the on-line training programs listed below can be utilized to provide certification for using dicamba in 2020.
Those who participate in the entire training class will receive a certificate of completion that can be used as proof of training for recordkeeping purposes. If you have taken a dicamba-specific training and did not receive a certificate by email, or cannot locate the email, please contact the company hosting the training for that record.
