Smaller Weeds are Easier to Control

Early season weed activity in your customers’ fields can deprive soybeans of vital soil nutrients and sunlight during key stages of crop development — making it all the more important to control weeds before they emerge.

By applying a residual herbicide in spring, growers can control weeds early, before they compete with the crop. Along with long-lasting weed control, an effective residual herbicide application sets the stage for optimal postemergence herbicide performance later in the season.

Southern Illinois University research shows that a grower can protect 6 bushels per acre by using a pre-post herbicide program versus making the first weed control application with glyphosate when weeds are 4 to 8 inches tall.
