The enormous cost of uncontrolled weeds

Early season weed competition can result in irreversible yield loss at harvest. Although most growers recognize the value of maintaining herbicide programs proven to work on their farm, unsteady commodity prices may sway some growers to gamble on switching programs in 2017. One scenario growers cannot afford is skipping a residual herbicide.

“It will be increasingly common for growers to spend more time shopping for the best deals on active herbicides they’re familiar with,” says Scott Pringnitz, market development specialist, Dow AgroSciences. “Many growers understand that the best way to lower their cost per bushel or, in some cases, minimize their loss, is to choose inputs that provide the best yield results.”

Early season weed pressure can create the opposite effect — yield loss and more input costs later in the season. Although any weed can cause problems at high populations, waterhemp, Palmer amaranth, marestail, giant ragweed, morningglory and burcucumber are the most challenging to manage with single-application herbicide programs. Research from South Dakota State University found that early season weed competition can result in a 40-bushel-per-acre yield loss.

“Growers simply cannot be profitable if they fail to keep these weeds under control,” Pringnitz says. “A residual herbicide is the best money spent in controlling many of these challenging weeds. If weeds are allowed to get very large, growers may not have any options to control them or protect yield regardless of how much he or she is willing to spend.”

Corn growers can gain powerful residual control of early season weeds, including waterhemp, marestail and Palmer amaranth, with Resicore® herbicide. Resicore has a novel formulation of three leading active ingredients and three nonglyphosate and nonatrazine modes of action for residual control deep into the growing season.

To help growers manage their input costs, Dow AgroSciences has partnered with Rabo AgriFinance to offer zero percent financing on Resicore and other crop protection products. Learn how your customers can apply at
