EPA Sets Regulatory Actions on Dicamba for 2018

EPA Sets Regulatory Actions on Dicamba for 2018

EPA has reached an agreement with Monsanto, BASF, and DuPont on measures to further minimize the potential for drift to damage neighboring crops from the use of dicamba formulations used to control weeds in genetically modified cotton and soybeans.

Manufacturers have voluntarily agreed to label changes that impose additional requirements for “over the top” use of these products next year including:

  • Classifying products as “restricted use,” permitting only certified applicators with special training, and those under their supervision, to apply them; dicamba-specific training for all certified applicators to reinforce proper use;
  • Requiring farmers to maintain specific records regarding the use of these products to improve compliance with label restrictions;
  • Limiting applications to when maximum wind speeds are below 10 mph (from 15 mph) to reduce potential spray drift;
  • Reducing the times during the day when applications can occur;
  • Including tank clean-out language to prevent cross contamination; and
  • Enhancing susceptible crop language and record keeping with sensitive crop registries to increase awareness of risk to especially sensitive crops nearby.

Manufacturers have agreed to a process to get the revised labels into the hands of farmers in time for the 2018 use season. EPA will monitor the success of these changes to help inform our decision whether to allow the continued “over the top” use of dicamba beyond the 2018 growing season. When EPA registered these products, it set the registrations to expire in two years to allow EPA to change the registration, if necessary.

“Today’s actions are the result of intensive, collaborative efforts, working side by side with the states and university scientists from across the nation who have first-hand knowledge of the problem and workable solutions,” said EPA Administrator Scott Pruitt. “Our collective efforts with our state partners ensure we are relying on the best, on-the-ground, information.”

In a series of discussions, EPA worked cooperatively with states, land-grant universities, and the pesticide manufacturers to examine the underlying causes of recent crop damage in the farm belt and southeast.  EPA carefully reviewed the available information and developed tangible changes to be implemented during the 2018 growing season. This is an example of cooperative federalism that leads to workable national-level solutions.

Farmer Andy says:

This doesn’t seem like much of a change or improvement from the current label, just very minor tweeks, and we all know how the current label restrictions worked out. Any tweeks on the minimum wind speed to prevent inversion issues? I predict the issue will continue next year.

Retailer Bob says:

These changes will not help the off-target movement problem. Many of our customers applied the “new” practices in 2017. Making it a restricted use pesticide also will not help. Sorry folks, what will help is that everyone plant the resistant bean. And, that also will not happen. This is my opinion.

Vapor Drift from bare ground is related to temperature and humidity
moisture and inversion layers.

Contact Dr Don Penner Michigan State…the about restrictions do no cover the major issue.

Concerned says:

I believe a calendar date application cut-off is needed to be added to the label by region. Making the product restricted use will not have much of an impact on the use of the product other than the custom applicators are probably going to see an increase in acres as the farmer will want to transfer the application liability to someone else.
