How to Choose the Right Herbicide Program for 2021
As 2020 comes to a close, it’s important to evaluate how your weed management program performed, so you can make informed choices about next year’s inputs.
We know that weeds are damaging because they compete with young crops for vital resources. But it’s important to keep in mind just how quickly this competition can cause damage. The Iowa State University Extension reports that weeds can impact yield potential as soon as they begin to steal light, water and nutrients from the crop – and that can happen before you even realize a weed is in your field.
With that in mind, here are the steps you can take to choose the right herbicides for your farm and what impact they will have:
- Consider which weed species and weed escapes you noticed in your fields throughout the season and at harvest. This will be important information to help you choose the herbicide applications that will control those flushes next year.
- When evaluating types of herbicides, it’s important to choose those with broad-spectrum control and residual activity. The right herbicide program will help you stay on top of weeds and avoid spending more money late in the season to clean up escapes.
- An effective spring burndown will be important to avoid yield-robbing, early-season weed competition.
- To keep fields clean, you should apply overlapping residual herbicides at full-label rates. This holds true even if weather affects timing, as it has in several recent seasons. A preemergence herbicide with long-lasting residual can help mitigate an issue if environmental conditions prevent a timely post-emergence application.
- Take advantage of early-purchase discounts for the herbicides you identify for your program.
Herbicide Solutions for Next Season
In corn, we recommend Acuron® herbicide. Acuron contains 4 active ingredients (AIs), including the unique component bicyclopyrone, and 3 effective sites of action. Bicyclopyrone works with the other AIs in Acuron to provide powerful weed control, longest-lasting residual and proven crop safety to enable Acuron to better protect corn from tough, yield-robbing weeds. Lower weed competition leads to more bushels and more revenue potential. When used in a preemergence application at full label rates, Acuron helps you find 5-15 more bushels an acre than any other corn herbicide.*

In soybeans, the Syngenta soybean herbicide portfolio includes flexible preemergence herbicide options, including Boundary® 6.5 EC, BroadAxe® XC and Prefix®, for effective weed control across a range of geographies, soil types and trait systems.
For dicamba-tolerant soybeans, we recommend an early post-emergent application of Tavium® Plus VaporGrip® Technology herbicide, the market’s first premix residual dicamba herbicide. Through the contact control of dicamba, Tavium manages the emerged weeds you see, and through the residual control of S-metolachlor, it manages the weeds you don’t see yet. This powerful combination provides up to 3 weeks longer residual control than dicamba alone. Sequence® herbicide also delivers post-emergent knockdown and residual control of weeds such as pigweed, crabgrass and annual grass in soybeans.
