Description
Penoxsulam, developed and produced by Dow AgroSciences LLC (Dow AgroSciences), is a trizolo pyrimidine herbicide applied in paddy fields with the widest herbicidal spectrum. It has great effect not only in aquatic weeds control but also in barnyard grass which has resistance to herbicides like quinclorac, propanil and sulfonylurea. With aquatic weeds’ higher resistance, penoxsulam plays a more vital part in weeds control. Penoxsulam is an acetolactate synthase inhibitor herbicide. It provides broad-spectrum control of many annual, biannual, and perennial weeds.
It is used mainly as a post-emergency foliar spray or a granular formulation for the control of broadleaf, sedge, and grass weeds in transplanted, dryseeded, and water-seeded rice. It is also effective against broadleaf weeds in corn, sorghum, wheat, barley and other cereal crops, lawns, golf courses, parks, cemeteries, athletic fields, sod farms, tree and vine crops, range and pasture, roadsides, and other crop and non-crop uses.
As penoxsulam does not bind strongly to either soil or sediments, it tends to be very mobile in both aqueous and terrestrial environments, which makes it a contaminant to groundwater. Penoxsulam is registered for use in Germany, France, Portugal and the USA.

Uses
Penxosulam is a triazolo-pyrimidine sulfonamide herbicide, which is used to control the growth of annual grasses, sedges, and broadleaf weeds in rice agriculture. The compound inhibits the synthesis of acetolactate and targets the biosynthesis of branch-chained amino acids, a metabolic pathway found in plants, fungi, and microorganisms. Acetolactate synthase (ALS) inhibitors are present in most effective herbicides. They are used in agriculture because they show a broad weed control spectrum, crop selectivity, are safe to humans, and can be applied at relatively low usage rates. Herbicide.
