Product Description

Agrochemical Intermediates Herbicide Penoxsulam CAS 219714-96-2 for Rice Protection


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.

3. Applications


Mode of Action

Broadest spectrum herbicide for rice. Systemic herbicide to inhibit the acetolactate synthase, absorbed by stem, leaf, budlet, root. It will inhibit the plant's growth, chlorosis appears on the growing point, the terminal bud will turn red in 7~14 days and necrotic, the plant will die in 2~4 weeks.

Long duration of 30~60 days, one off application can control the whole season's weed.

It can also control the weeds which be resisted to Bensulfuron methyl.

It cannot kill Leptochloa chinensis, so it can be used with Cyhalofop-butyl to control it.

Crops rice
Control cockspur grass, annual sedge, most broadleaved weeds
