EPA has released three new dicamba over-the-top herbicide labels for XtendiMax (Bayer), Engenia (BASF) and Tavium (Syngenta).

FeXapan -- Corteva Agriscience's marketed version of XtendiMax -- is not yet registered for use, but the company is expected to seek a federal registration.

EPA will no longer permit states to use Section 24(c) special local needs labels (SLNs) to add further restrictions to the federal dicamba labels, as many states have done in the past.

If states want to further restrict the federal label, they now must use Section 24(a) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), which requires states to go through a lawmaking or rulemaking process.


Many of the 2020 label restrictions remain the same as the 2018 and 2019 labels. Unchanged requirements include:

> All three herbicides remain restricted-use pesticides (RUP) that can only be handled by certified applicators.

> Applications are still limited to 3 to 10 mph wind speeds, at sprayer speeds at or below 15 mph, with boom height no more than 24 inches above the crop canopy.

> Applications are still prohibited within 48 hours of a rain forecast that could be expected to exceed soil capacity of a field.

> Applications are still prohibited during temperature inversions and are limited to one hour after sunrise and two hours before sunset.

> Applications are still banned if the wind is blowing toward a sensitive crop or area.

> Applicators are still required to check for the presence of endangered species in their county via the EPA's Bulletins Live! Two website.

> Applicators are still required to check a sensitive crop registry for each field before applications.

> The use of AMS (ammonium sulfate) and nonapproved nozzles are still banned from use with these herbicides.

> Triple-rinse cleanout procedures are still required with all three herbicides.
