Imazethapyr is a kind of organic heterocyclic herbicides, belonging to the imidazolinone compounds, the isopropylamine salt suitable for control of all weed, of Cyperaceae weeds and annual and perennial monocotyledonous weeds and broad-leaved weeds and miscellaneous have excellent herbicidal activity, is used in the bud or bud, can be quickly absorbed by the roots and leaves of plants, inhibit the biosynthesis of plant side chain amino acid (valine, leucine and isoleucine), break down proteins, which made the weed growth was inhibited. His cause of death.



Biochemistry Branched chain amino acid synthesis (ALS or AHAS) inhibitor. Hence reduces levels of valine, leucine and isoleucine, leading to disruption of protein and DNA synthesis. Selectivity in soya benas and peanuts is attributed to rapid detoxification via hydroxylation and glycosylation. Mode of Action Systemic herbicide, absorbed by the roots and foliage, with translocation in the xylem and phloem, and accumulation in the meristematic regions. Uses Control of many major annual and perennial grass and broad-leaved weeds in soya beans and other leguminous crops. Applied pre-plant incorporated, pre-emergence, or post-emergence. Phytoxicity Non-phytotoxic to soya beans and other leguminous crops, when used as directed.
