Why You Should Read Herbicide Labels: Part 1

April 14, 2020

Colusa, IL, 2018: Applying herbicides to a corn field.

Whether you’ve recently purchased a big-ticket item like a new car or something much smaller, there’s a good chance the product came with a set of detailed instructions and the disclaimer: always read and follow label instructions. And even though most of us tend to overlook those directions, they ensure we use the product correctly and safely – and should be thoroughly reviewed. Reading and following the label instructions is especially important when it comes to corn and soybean herbicides. Minor missteps in the application process, timing, rate, etc. can have a major impact on performance and lead to poor weed control and costly corrective measures.

A One-Stop-Shop for Critical Information

This image shows the Acuron product label

A snippet from the Acuron® corn herbicide label clearly shows the 4 active ingredients and their respective site of action (SOA) group numbers: atrazine = SOA group 5; bicyclopyrone = SOA group 27; mesotrione = SOA group 27; S-metolachlor = SOA group 15.

Every herbicide’s label tells you exactly what active ingredients and SOA groups it includes. Remember: select herbicides with multiple and effective SOAs specifically targeted to your toughest driver weeds (i.e., the weeds that are causing the most problems and yield loss) and then apply them at full labeled rates.

In addition, labels also provide detailed information on crop usage, interval windows, application timing, rates, adjuvants, spray equipment, mixing procedures, personal protective equipment (PPE), cleaning, storage and disposal.

If you don’t have access to the physical label, check the product’s webpage for the current EPA-approved label. And you can always consult with your local Syngenta representative or retailer if you have questions or need further clarification.

For corn, we recommend Acuron corn herbicide. Acuron contains 4 active ingredients, including the unique component bicyclopyrone, and 3 effective sites of action, which enable it to better protect corn from tough, yield-robbing weeds and outyield any other herbicide. When used in a preemergence application at full label rates, Acuron helps you find 5-15 more bushels an acre.*

Calculate how much more potential revenue you could earn with an extra 5-15 bushels.

For dicamba-tolerant soybeans, we recommend Tavium® Plus VaporGrip® Technology herbicide, the market’s first premix residual dicamba herbicide. Tavium has multiple effective sites of action that work against a broad spectrum of broadleaf and grass weeds, and contains built-in residual control to maintain clean fields throughout the season. Tavium is best used as an early post-emergent herbicide and can follow Boundary® 6.5 ECBroadAxe® XC or Prefix® herbicides in soybeans – along with others. Tavium controls 21 different weeds when applied preemergence and 63 weeds as a post-emergent herbicide.
