EPA Extends Syngenta Dicamba Herbicide Registration: What It Means for 2021

It’s that time of year to make decisions about which inputs, including herbicides, to use next season. On October 27, the U.S. EPA announced that they were renewing and extending the registration of dicamba for over-the-top use in dicamba-tolerant soybeans and cotton for 2021 and beyond. Below are 3 key questions to ask yourself as you evaluate your 2020 weed management program and plan for 2021.

Which dicamba topics would you like to learn more about?

Does Your Herbicide Control Your Problem Weeds?

Which weed species did you notice at harvest and during your in-season scouting? If you use a herbicide that isn’t equipped to manage the problem weeds in your fields, you might spend more money over the course of the season to clean up flushes with costly resprays.

Does Your Herbicide Deliver Residual Control?

As we’ve seen in several recent growing seasons, unpredictable challenges like adverse weather conditions can disrupt normal application timing. The herbicides you use will play a role in determining how much flexibility you have for applying your second pass. A chemistry that provides residual control will help you manage weeds until you can apply a post-emergence herbicide or until your crop reaches canopy.

Does Your Herbicide Feature Multiple Effective Sites of Action?

Another way to avoid costly resprays is to apply herbicides with multiple effective sites of action to control weeds the first time, without needing further applications later in the season. Effective herbicides also help delay the onset of weed resistance. If a weed is only injured by a herbicide, it could recover and evolve a tolerance to that chemistry.

The Syngenta Dicamba Herbicide

The U.S. Environmental Protection Agency (EPA) has extended the registration for Tavium® Plus VaporGrip® Technology herbicide in dicamba-tolerant soybeans and cotton. As the market’s first dicamba herbicide premix, Tavium contains built-in residual control to manage resistant weeds and maintain clean fields throughout the season. Tavium, a proprietary Syngenta premix, will be available for the 2021 growing season, subject to state approvals.

Tavium can be used preplant, at planting and early post-emergence on dicamba-tolerant soybeans and cotton. A combination of the contact control of dicamba and the residual control of S-metolachlor, Tavium is a convenient premix that manages key ALS-, PPO- and glyphosate-resistant broadleaf and grass weeds.

Use Tavium early post-emergence following Boundary® 6.5 EC, BroadAxe® XC or Prefix® herbicides in soybeans, and Caparol® 4L or Reflex® herbicides in cotton. When used in a preemergence application, Tavium can be followed by Sequence®, Flexstar® GT 3.5 or Prefix herbicides in soybeans.

When you choose your 2021 herbicide program, consider Tavium as your dicamba option.
