When Comparing Herbicides, Consider All Factors

When evaluating types of herbicides and how to tackle weed resistance, balance the cost of the application with the control it provides – and the resulting yield benefits.

Let’s examine a few factors more closely.

Broad-spectrum Control is Paramount

Choose a herbicide equipped to tackle a variety of tough weeds. Through in-season scouting, you should have an idea of the major weed issues in your fields.

Ensure your herbicide is labeled for full control – not just suppression – of your biggest problem weeds. If you’re not using the right herbicide for your specific weed pressures, you may spend more money over the course of the season cleaning up weed escapes, turning a bargain herbicide into a bad deal.

Residual Control Should Top the List of Crucial Considerations

Herbicide application timing can be out of our control when up against weather. A herbicide with long-lasting residual can help ensure your fields are protected until you’re able to apply a second pass or until crops reach canopy.

How Effective Is Your Herbicide Against Weeds?

We want to kill the weeds, not simply injure them. If an injured weed recovers from a herbicide application, it may do so with a tolerance to that herbicide.

That’s why it’s important to use herbicides that are effective against particular weed species and types of resistance that may already be in your fields. The best way to do this and maximize profit potential is to use herbicides with multiple effective sites of action. Otherwise, you risk spending more on additional herbicide applications later in the season to clean up escapes. This can also create a long-term, costly weed resistance management problem in your field.

Weed management requires careful deliberation, but the right program can actually pay you back at the end of the season. By preventing early-season weed competition, some herbicide programs also increase yields.

This season, try Tavium® Plus VaporGrip® Technology herbicide for dicamba-tolerant soybeans and cotton. It’s the market’s first premix residual dicamba herbicide containing 2 effective sites of action. Through the contact control of dicamba, Tavium controls the weeds you see, and through the residual control of S-metolachlor, it protects you from the weeds you don’t.

In addition to providing broad-spectrum residual control and resistance management benefits, when used as part of a program with a strong preemergence herbicide, Tavium-treated soybeans yield up to 1.9 bu/A more than those treated with XtendiMax® With VaporGrip Technology.[1] 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 you add up its benefits, Tavium could be the one for you next season.
