Make An Addition to Your Weed Resistance Toolkit

We’re keeping a close eye on the start of the 2020 growing season. A larger-than-normal weed seed bank may turn into a flush of weeds that requires all available management options to control.

In-season weed management typically takes priority each year, but you may unintentionally be neglecting weed resistance management – an action that has fewer immediate results. We encourage you to maintain a longer-term focus, as herbicide resistance in weeds is spreading to more fields each year.

The weed management decisions you make today should be sustainable for the future.

The key principle of weed resistance management is to use multiple effective sites of action. The University of Illinois College of Agricultural, Consumer and Environmental Sciences research says growers who use 2.5 sites of action on average are 83 times less likely to develop herbicide resistance over only 1.5 sites of action. And Syngenta research has found that using programs with up to 4 effective sites of action can delay resistance by up to 2 decades.

In addition to using cultural practices, such as tillage or crop rotation, be ready to pounce on weeds with an effective spring burndown followed by a 2-pass application at full rates.

Dicamba herbicides are still a relatively new technology for soybeans and cotton. They bring an additional site of action to fields, making them a strong addition to weed resistance management programs. Tavium® Plus VaporGrip® Technology herbicide is the market’s first premix residual dicamba herbicide for fighting weeds and resistance in soybeans and cotton.

Tavium contains 2 effective sites of action for both contact (dicamba) and residual (S-metolachlor) control to manage key ALS-, PPO- and glyphosate-resistant weeds.

This gives you 2 important advantages: It maintains even coverage and control, while also helping to preserve herbicide technology and delay herbicide resistance.

The best fit for Tavium is as an early post-emergent herbicide. It can follow Boundary® 6.5 EC, BroadAxe® XC or Prefix® herbicides in soybeans – along with many others – and can follow Caparol® 4L or Reflex® herbicides in cotton. Using Tavium as part of an integrated weed management program with the these soybean and cotton herbicides provides 3 effective sites of action, helping to delay weeds from developing resistance to this technology.

With Tavium as part of your herbicide program in 2020, you can be ready to control the weeds that may be overwintering in your fields.
