Plant first, spray later. Growers tend to rely on this routine when untimely rain makes it difficult to plant on schedule. And when weather delays planting, growers don't have time for a preemergence herbicide application, which can put yield at risk.

During wet springs, like the ones growers have experienced this year and last season, spraying flexibility is even more important to growers, says Brittany Loewen, corn herbicides product manager at Dow AgroSciences.

"When there's wet weather early in the planting season, a grower's first priority is to get corn in the ground and spray later," Loewen says. "SureStart herbicide allows more time to spray, with flexibility from preemergence to 11-inch corn."

Mother Nature runs on her own schedule, and so do weeds. Early season weed competition can significantly reduce yield by robbing developing corn plants of sun, water and nutrients. And once yield is diminished, it's not coming back.

"Today, some of the toughest weeds are able to survive glyphosate-only applications, including giant ragweed, waterhemp and marestail," Loewen says. "Without the use of a residual herbicide before a glyphosate application, these weeds have a head start on reducing yield potential."

Loewen recommends a two-pass weed control program containing a residual herbicide with multiple modes of action, such as SureStart® herbicide, which is proven to stop weeds more effectively than glyphosate alone.

This year wasn't the first time weather delayed corn planting, and it won't be the last. Overcome weather delays by choosing a herbicide with broad-spectrum control of weeds and flexible application timing.
