Answering Your Tavium Application Requirements Questions

February 22, 2021

As we enter a new growing season, you might have questions following the U.S. Environmental Protection Agency’s dicamba announcements in 2020.

Last October, the EPA extended registration for the Syngenta dicamba herbicide premix, 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, is available for the 2021 growing season, subject to state approvals.

But what are the application requirements for Tavium in 2021?

What is the Application Rate?

We always recommend applying herbicides at the full label rates to ensure you see the highest potential efficacy against tough weeds. For Tavium, the application rate is 3.53 pt/A in dicamba-tolerant soybeans and cotton. Along with applying full use rates, it is best to treat weeds early, when they are less than 4″ tall.

How Should you Plan for the Weather?

Weather can impact all aspects of your plan each season. For applications of Tavium and other dicamba herbicides, it’s important to know key weather conditions such as wind speed, potential for temperature inversion, impending rainfall and more.

Tavium may only be applied when winds are between 3 – 10 mph, and when rainfall that could exceed soil field capacity and result in soil runoff is NOT expected in the next 48 hours. Be sure to check your daily forecast before starting up the sprayer.

Time of day also matters. Do not apply Tavium until at least 1 hour after sunrise and no later than 2 hours before sunset.

Are There Restrictions in your Area?

Before you spray, be sure there is a 240′ downwind in-field buffer. And don’t forget that applicators must visit http://www.epa.gov/espp/ to determine if there are any additional restrictions on Tavium use within the area to be sprayed.

You’ll also need to apply only when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, nontarget crops) is minimal (i.e., when wind is blowing away from the sensitive areas).

What About your Sprayer and Equipment?

Check your label to find prescribed sprayer cleanout procedures that will help prevent contamination in sprayer loads following your application. When in doubt, check the label and be sure to carefully follow the instructions.

Another crucial step is ensuring you have an approved nozzle. The list can be found on our Tank Mix Partners page. These approved nozzles produce extremely-coarse to ultra-course droplet size. Tavium must be applied with one of these.

Additionally, make sure you do not exceed a sprayer boom height of 24” above the target weed or crop canopy and keep your sprayer under the limit of 15 mph.

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.

For an effective full-season herbicide program, use Tavium early post-emergence following Boundary® 6.5 EC, BroadAxe® XC or Prefix® herbicides in dicamba-tolerant soybeans, and Caparol® 4L or Reflex® herbicides in dicamba-tolerant 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.
