The Cocktail Age Of Herbicides

An old saying claims that in many difficult situations, “two heads are better than one.” In the crop protection products world, manufacturers have apparently taken this phrase to heart with many of their newest offerings.

In early July, Dow AgroSciences held its annual summer media event in Indianapolis, IN. Besides sharing information on the company’s rollout of Enlist Duo, crop conditions across the U.S. and nitrogen stabilizers, Dow AgroSciences took the opportunity to introduce its latest herbicide, Resicore. To control such problem weeds as lambsquarters, waterhemp, Palmer amaranth and marestail, Resicore features three active ingredients in its mix – acetochlor, mesotrione and clorpyralid.

“Resicore is designed to control weeds throughout the season,” said Luke Peters, corn herbicides product manager for Dow AgroSciences, announcing the introduction. “It will provide trusted residual control, resistance management and resounding yield potential as the core of growers’ weed control programs.”

Of course, Dow AgroSciences is by no means the first crop protection products supplier to take this “cocktail herbicide” approach. During the past year or so, many manufacturers have introduced new branded herbicides featuring three or even four active ingredients to help growers combat an increasing array of herbicide-resistant weeds.

Are your grower-customers using more multiple modes of action herbicides than in the past?

And given the state of crop protection product discovery, this approach makes sense, say market observers. Many have pointed out that research into finding the next single active ingredient to control weeds could be more than a decade off, or more. In the meantime, the industry will have to do the best it can to address the herbicide-resistant weed problem by utilizing the tools already available in its toolbox.

“I think the era of any product having less than three modes of action is probably over,” said Peters. “We feel that the best chance the industry has to control troublesome weeds is by blending several different modes of action products together, so I would expect to see more of these kinds of products going forward.”
