More time, improved soil health and reduced compaction are just a few advantages of implementing a no-till soybean system. And the list goes on.
“No-till can help reduce labor, fuel costs, and wear and tear on equipment from extra passes across the field,” says Joe Bolte, market development specialist, Corteva Agriscience. “This can also help free up equipment and resources during the spring — one of the busiest times of the year for growers.”
But, along with several advantages, a no-till system can pose challenges. One of those challenges is marestail. This weed thrives in no-till and reduced-tillage environments.
When marestail germinates in fall and is allowed to overwinter to spring, it is generally considered one of the most difficult weeds to control. Once it gets a hold in a field, marestail can significantly decrease yield.
“Tillage will control winter annuals [such as marestail] and early emerging summer annuals,” Bolte says. “But in a no-till environment, a burndown application will be needed to control these weeds.”
Controlling weeds when they are small is the key to any herbicide application. That’s why Bolte recommends a fall burndown, which will provide control when weeds are most susceptible.
“For maximum control, residual herbicides that are labeled for fall applications can be added to the tank,” Bolte says. “Many of these products will have burndown as well as residual activity. Adding an approved burndown tank-mix partner can also help broaden the burndown weed control spectrum.”
If you choose to not make a fall burndown application, a spring burndown will be even more critical. Early spring burndown applications can help control winter annuals and early emerging summer annuals when they are still small.
“Corteva offers many options for acres that will be planted to soybeans the following spring,” Bolte says. Here are some great options available for burndown applications:
