Since the introduction of Roundup Ready crops in the mid- to late-1990s, postemergence herbicides have played an increasing role in weed control for many crops including corn, soybean, cotton and wheat.

Effective preemergence herbicides are imperative for successful weed management.

Preemergence herbicides can aid in the control of troublesome weeds such as waterhemp and giant ragweed. They can also result in lower weed densities and a more uniform weed height at the time of postemergence herbicide application, aid in the management of herbicide-resistant weeds, and ultimately help protect crop yield potential and profitability.
