Advantages to stocking and applying low-use-rate herbicides
Typically, corn has been a crop with some of the highest volume herbicides applied for weed control. It hasn’t been unusual to have three quarts per acre of a herbicide used, and that hasn’t really gone lower in recent years as two or three herbicides have been tank mixed to provide multiple modes of action to kills weeds, including glyphosate-resistant weeds.
Waddington noted that using Capreno, with its two active ingredients, and adding up to 1 ½ pints of atrazine still results in an extremely low-use-rate herbicide mix. Plus, it provides three active ingredients to control most any weeds, including glyphosate-resistant ones. He said waterhemp is one of the biggest problems in his area of Illinois, but foxtail, fall panicum, cocklebur and other pigweed varieties are concerns, too.
Waddington said, “If a product didn’t work well and the use rate was low, the lower rate wouldn’t mean anything, but Capreno works.”
