The sulfonylureas have greater activity against broad-leaf weeds, but resistance has developed in some plant types.

And the herbicides are safe for humans and animals because they do not have the enzyme sulfonylurea molecules target. In short, Duke is a foliar herbicide with less activity via the soil. Sulfonylureas inhibit the plant enzyme, acetolactate synthase, resulting in impaired branch chain amino acid synthesis, and are generally more potent herbicides than the phenylureas. The sulfonylurea herbicides are a relatively newer class of SUHs. Herbicides vary in their potential to persist in soil. Usage: Prosedge israinfast after 3 hours, so best results occur when no rainfall or irrigation happens within 4 hours of application.

Last of all, do not exceed an annual application total of 113g/Ha per year. ALS inhibitors stop cell division and growth by inhibiting the biosynthesis of the essential amino acids .

Others conducting early field tests at a university concluded that there had to be an error in the instructions. Sulfonylureas inhibit the plant enzyme, acetolactate synthase, resulting in impaired branch chain amino acid synthesis, and are generally more potent herbicides than the phenylureas.
