COMMON NAME	Imazethapyr 98% TC	CAS NO	81335-77-5
CATEGORY	Herbicides	FORMULATION	C₁₆H₁₃CLF₃NO₄
PACKING	25KG/barrel, Other suitable packing can be adopted according to the requirements of customers.
APPLICATION	It is applied preplant incorporated, preemergence, at cracking, and postemergence. The compound controls weeds by reducing the levels of three branched-chain aliphatic amino acids, isoleucine, leucine and valine, through the inhibition of aceto-hydroxyacid synthase, an enzyme common to the biosynthetic pathway for these amino acids. This inhibition causes a disruption in protein synthesis which, in turn, leads to an interference in DNA synthesis and cell growth. The compound is used to control grasses and broadleaved weeds including barnyardgrass, crabgrass, cocklebur, panicums, pigweeds, nightshade, mustard, smartweed, velvetleaf, jimsonweed, foxtails, seedling johnsongrass, lambsquarters, morningglory and others
