Weed Control

More than 20 different types of herbicide-resistant weeds now exist in Illinois and Iowa and nearly as many in surrounding Midwest states. Weed resistance has grown from lambsquarters resistance to atrazine confirmed in Illinois and kochia resistance to atrazine confirmed in Iowa, both in 1985, to the high level of resistance today. Common waterhemp is the most prevalent herbicide-resistant weed in Illinois, with Palmer amaranth quickly catching up. In Iowa, horseweed is the most widespread herbicide-resistant weed. Horseweed’s resistance to glyphosate in 2011 is the most recently confirmed case found in Iowa.

The keys to battling herbicide-resistant weeds include a focus on

   Early-season control;

   Use of a preemergence herbicide at planting;

   Selecting the right herbicide for the right weed at the right time;

   Early postemergence applications with follow-up, if needed;

   And diversification of herbicide sites of action.

   Cover crops and crop rotation are also commonly recommended practices.
