DTN (PROGRESSIVE FARMER): New Dicamba Labels - October 28, 2020
A Breakdown of Changes to the 2020 Dicamba LabelOctober 28, 2020
By Emily Unglesbee Emily.unglesbee@dtn.com
ROCKVILLE, Md. (DTN) -- EPA released three new dicamba over-the-top herbicide labels on Tuesday: XtendiMax (Bayer), Engenia (BASF) and Tavium (Syngenta).(FeXapan -- Corteva Agriscience's marketed version of XtendiMax -- is not yet registered for use, but Corteva confirmed to DTN that the company will be seeking a federal registration of the product now that XtendiMax is registered).
The three new labels come with many pages of details and
use restrictions, some old, some new. DTN analyzed each one to see what changes
were made from the 2018 registration, as well as what might look familiar to
applicators. Here's the breakdown.

EPA also announced another change during its dicamba registration decision. The agency 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, mostly with temperature and cutoff dates.
From now on, the EPA will only allow states to create additional uses via 24(c) labels, per the language of the law. If states want to further restrict the federal label, they will have to use Section 24(a) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), which requires states go through their lawmaking or rule-making process.

WHAT DID NOT CHANGE
Many of the 2020 label restrictions remain the same
compared to the 2018 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
to 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 2
website.
-- Applicators are still required to check a sensitive
crop registry for each field before applications.
-- The use of AMS (ammonium sulfate) and non-approved
nozzles are still banned from use with these herbicides.
-- Triple-rinse cleanout procedures are still required
with all three herbicides.

Greetings,
Dr. Ken Obasa, Pathology Specialists – Amarillo, has put together this handy list for seed dress fungicides for wheat this year. Should be a great quick check for control expectations. 
Thanks,
