DuPont SU Herbicides

Most of the herbicides marketed by DuPont belong to a class of herbicides known as sulfonylureas (SUs).

SUs control a wide spectrum of weeds at very low application rates, break down rapidly to nontoxic compounds, and have low toxicity values because they target an enzyme — acetolactate synthase (ALS) — found in plants but not animals.

DuPont discovered the SU class of chemistry. U.S. patents originally secured on DuPont products containing these SUs are now expiring, and generic products have begun entering the market. These products are marketed to growers as being the same as branded DuPont SUs – only cheaper.

That’s just not true. While generic producers seek to copy our products, they typically use active ingredients not produced by DuPont.

Why does this matter? Since SUs are applied at rates as low as 0.1 ounce per acre, even small ingredient deviations can result in application errors and inconsistent performance. We’ve collected and evaluated generic SU products from around the world and found a substantial number do not contain the active ingredient levels specified on the label and/or contain contaminants.

Why take the chance? With our stringent DuPont manufacturing standards, you can be confident that our SU products will perform as stated on the label.

When it comes to the reliable weed control of sulfonylurea herbicides, count on DuPont.
