Early weed pressure can drastically impact corn yield

Early season weed competition can have a serious and irreversible effect on corn yield.

Weeds as small as 2 inches can reduce corn yield if they are present at a high density early in the season, according to research from Iowa State University. For example, giant foxtail at 2 to 4 inches of height can reduce yield by 0.5 percent per day. At 6 to 8 inches tall, 1.5 percent yield loss can occur per day.1

Early in the season, weeds can starve young corn plants of essential nutrients, sunlight and moisture. When weed control measures are delayed, there is a greater chance for yield reduction. To protect yield potential from weed pressure, it’s important growers control weeds at the start of the season to reduce competition during early and critical stages of crop growth.

A preemergence residual herbicide, such as SureStart® II herbicide, controls weeds early so corn can start strong without competing with weeds.

SureStart II can provide your customers with early season control of more than 60 broadleaf weeds and grasses. With a wide application window from preplant up to 11-inch corn, SureStart II provides application flexibility and residual control corn growers trust for proven performance on high-anxiety weeds, including giant foxtail, marestail and Palmer amaranth.
