Winter annual weeds can emerge soon after harvest, and it’s important to scout for them to determine whether a fall herbicide program is necessary. Here are a few questions to ask going into fall.
What type of winter annual weeds are most common in your customers’ fields? The most difficult winter annual weeds across the Corn Belt include marestail, henbit, purple deadnettle and chickweed. These weeds are becoming more common as growers have switched to no-till production.
When should weeds be controlled? There is a good chance weeds emerging in the fall will become a problem in spring. Look at weed density. A high weed density in fall is a good indication that control measures are needed before winter.
How are winter annual weeds best managed? A fall herbicide program can mitigate weed pressure before spring. Using a fall burndown with a residual herbicide such as SureStart® II herbicide can help keep weeds at bay over winter and into spring so the crop gets a clean start at planting.
