  • Mechanism of Action:
  • Cyhalofop-butyl is aromatic oxygen phenoxy acid herbicides in only on rice with high safety, variety, and this kind of other varieties, but also inner suction conductive herbicides. By the plant leaf blade and leaf sheath phloem conduction, absorption, accumulation in plant meristem zone, resist acetyl-coenzyme A carboxylase ( ACCase ), the fatty acid synthesis, cell growth and division can not be normal, membrane systems containing lipid structure damage, finally caused the plants to die. From Cyhalofop-butyl is absorbed into the weeds death slowly, generally need to 1-3 week. Weed in after application of the symptoms are as follows: four-leaf stage shoots atrophy, leading to death. Two leaf period old leaves changes were minimal, maintain green.
