Reducing the weed seed bed
Alongside your customers, you create tailored herbicide programs each season to keep weeds from robbing corn and soybeans of critical moisture, nutrients and yield. Despite those efforts, late-season weeds may emerge and negatively impact harvest efficiency.
Few things lower harvest efficiency more than having to stop the combine and climb down to clear a clog from the corn or grain header. But there are ways to avoid that scenario by helping customers take steps in the fall to lower weed pressure in the spring.
Keep the combine as clean as possible to avoid transferring weed seeds from field to field. Plan logistics to harvest fields with heavy weed pressure last. Note weed escapes while harvesting and use that information when building next season’s herbicide program.
Get with the program
Next year’s success starts with this year’s harvest because weed control is an ongoing process that can pay dividends the following season. A good burndown will help manage problem weeds in the fall and give customers a head start on controlling spring weeds.
Consider recommending a herbicide program that uses a program approach, placing key weed control elements throughout the production year. Follow a fall or spring burndown with a preemergence herbicide application or tank mix with multiple modes of action, plus products that provide residual activity, to help the crop reach canopy faster and reduce weed competition.
Always scout fields 10 to 14 days after each application to confirm weed control, identify possible weed escapes and note areas of missed coverage. The value of a program approach may be realized by controlling those late-season weeds that cause unneeded problems during harvest.
Get to work now: Fall weeds and control solutions
To manage problem weeds in the fall, like henbit and marestail, your customers should proactively build an agronomic foundation now that provides good weed control in corn, soybeans and other row crops while helping limit deposits into next year’s weed seed bank.
A reliable burndown solution like Elevore® herbicide can control broadleaf weeds such as henbit, lambsquarters and marestail. It also offers control of labeled broadleaf weeds without regrowth. With a low use rate, Elevore herbicide is well-suited for fall or spring burndown in reduced- and no-till production systems.
To avoid playing catch-up during the growing season, consultants and weed experts know that starting clean is a key first step to staying clean throughout the season. A program approach that uses preemergence and postemergence applications helps you stay ahead of weeds.
A strong preemergence corn herbicide such as Resicore® REV herbicide brings three proven active ingredients, strong residual activity to control tough broadleaf and grass weeds early and offers tank-mix flexibility, allowing you to customize a weed control program. For soybeans, Kyber® Pro herbicide and Sonic® Boom herbicide also deliver multiple modes of action and long-lasting residual activity for reliable early-season weed control.
For postemergence in corn, Kyro® herbicide has three modes of action for powerful in-season and residual activity, making it a perfect fit in a two-pass program approach. In soybeans, Enversa™ herbicide is a proprietary, encapsulated acetochlor (Group 15) with long-last residual activity and tank-mix flexibility – especially with Enlist One® herbicide for Enlist E3® soybeans.
The encapsulated acetochlor complements tank-mix partners by allowing Enversa herbicide to drive to the soil and provide a residual barrier against weeds yet to emerge.
Finish strong to win
You and your customers don’t take time off and neither do weeds. So, their weed management plan shouldn’t either. Taking these steps with your customers this fall will pay dividends in improved weed control during next year’s harvest.
