Have you ever used herbicide Isoxaflutole?

Herbicide: Isoxaflutole

herbicide, an inhibitor of the enzyme p-hydroxy phenyl pyruvate dioxygenase (HPPD), isoxaflutole,

Summary

Isoxaflutole (5-cyclopropyl isoxazol-4-yl-2-mesyl-4-trifluoromethylphenyl ketone) is a novel herbicide for preemergence control of a wide range of important broadleaf and grass weeds in corn and sugarcane producing characteristic foliar bleaching activity in susceptible species prior to plant death. Following either foliar or root uptake, isoxaflutole is rapidly converted to a diketonitrile derivative (2-cyclopropyl-3-(2-mesyl-4-trifluoromethylphenyl)-3-oxopropanenitrile) by opening of the isoxazole ring. This diketonitrile undergoes degradation to a benzoic acid derivative (2-mesyl-4-trifluoromethyl benzoic acid) in treated plants and the extent of this degradation is correlated to the degree of susceptibility, being most rapid in tolerant corn and slowest in susceptibleAbutilon theophrasti.

Advantages:

• Anti-resistant: Isoxaflutole is effective against weeds resistant to other herbicide classes such as glyphosate and atrazine.
• Reactivation: The reactivation ability of Isoxaflutole has proven its value with herbicides for the corn market. Reactivation is the power to control weeds after they have emerged with an activating rainfall event. Many herbicides cannot control late-emerging weeds; therefore, the weeds survive to compete with the crop. Field studies show that through reactivation the active ingredient can be taken up by weed roots with just a half-inch or more of rain, bleaching and killing late-emerging weeds that are up to two inches tall.

Mode of action

Isoxaflutole inhibits the 4-hydroxyphenylpyruvate dioxygenase (HPPD) enzyme in plants. This enzyme is key to the production of pigments and the development of chloroplasts in plant tissues. By inhibiting pigment and chloroplast biosynthesis, emerging plant tissue is bleached (white to pale yellow).
