Take Care of Early Spring Weeds Before Planting

As you’re finalizing plans for spring, consider adding a spring burndown herbicide application if winter or spring annual weeds are a problem in your fields. Winter annuals, including marestail, overwinter and resume growing as soon as temperatures warm in the spring. When fields are fit to work, it’s a good idea to tackle these weeds because they often have the competitive advantage over the crops you intend to plant. In addition to stealing water and nutrients from the soil, weeds can create challenges for planting.

Here are some tips to manage weeds so your crops get a strong start.

Scout fields to identify weeds

Identifying weeds that are most troublesome early in the season can help you plan the most effective spring burndown application. Marestail, in particular, has shown resistance to glyphosate and ALS-inhibitor herbicides. Herbicides including Verdict® and Zidua® PRO can increase the consistency of marestail control. Both herbicides offer residual benefits, which can help extend weed control to keep fields clean during critical stand establishment. 2,4-D and dicamba are also effective for spring burndown applications.

Make timely spring burndown applications

As mentioned, winter annual weeds start growing as soon as temperatures warm. That means by the time you may be ready to plant, those weeds may have already entered reproductive stages, which makes them more difficult to control. Managing weeds while they are still small will help increase the efficacy of your herbicide application.

Follow herbicide label instructions

It won’t pay to cut corners with your spring burndown applications. Consult the herbicide label to ensure you’re using the right carrier type, volume, nozzles and partner products based on your weed pressure and environmental conditions. Also, consider that weed control will be best when weeds are actively growing and metabolizing herbicide active ingredients. Generally, sunny, warm days (temperatures 55 degrees or above) promote more successful applications.

Boost your herbicide’s performance

Adding the right tank-mix partners, including effective adjuvants, can help improve herbicide coverage and weed control. Even small weeds can rob emerging crops of valuable moisture and nutrients, which can limit yield potential. Adding an effective adjuvant, including StrikeLock®, is an economical way to enhance herbicide performance and ensure you’re getting the most out of the dollars you’ve spent.
