Isoxaflutole and metribuzin interactions in isoxaflutole-resistant soybean

Effect of soil properties on the degradation of isoxaflutole and the sorption-desorption of isoxaflutole and its diketonitrile degradate.

The transformation of isoxaflutole (ISOX) to its herbicidally active diketonitrile degradate (DKN) was significantly enhanced in the presence of soil and occurred more rapidly in systems containing soil with a greater soil pH. Sorption-desorption of ISOX and DKN in five soils collected within a field revealed both ISOX and DKN were more readily sorbed to soils with greater organic matter, clay ...

Toxicology of glyphosate , isoxaflutole , dicamba and possible combination effects

Adsorption of isoxaflutole degradates to aluminum and iron hydrous oxides.

Isoxaflutole is a preemergence herbicide that has been marketed as a substitute for atrazine. It is rapidly transformed to a more stable and soluble diketonitrile degradate (DKN) after field application and can further degrade to a benzoic acid degradate (BA) within soil. However, no previous research has been conducted to investigate DKN and BA sorption to metal oxide minerals. The primary obj...

Effects of moisture, temperature, and biological activity on the degradation of isoxaflutole in soil.

The effects of several environmental factors on the dissipation, transformation, and mineralization of isoxaflutole were investigated in laboratory incubations. In the soil, isoxaflutole hydrolyzed to a diketonitrile derivative, which is the active form of the herbicide. The diketonitrile was then metabolized to an inactive benzoic acid derivative and later into two unknown products, which were...

Reaction pathways of the diketonitrile degradate of isoxaflutole with hypochlorite in water.

Isoxaflutole (IXF; Balance) belongs to a new class of isoxazole herbicides. Isoxaflutole has a very short half-life in soil and rapidly degrades to a stable and phytotoxic degradate, diketonitrile (DKN). DKN was previously discovered to rapidly react with hypochlorite (OCl-) in tap water, yielding the benzoic acid (BA) degradate as a major product, but the complete reaction pathway and mechanis...
