Cyhalofop-butyl is the only type of herbicide in the aryl oxygen phenoxy propionic acid herbicide which is highly safe to rice. It is an endogenous herbicide.
Cyhalofop-Butyl Cas:122008-85-9
The leaves and leaf sheaths of plants absorb, phloem conduction, accumulate in the plant meristem area, resist acetyl coenzyme A carboxylase (ACCase), so that fatty acid synthesis stops, cell growth and division cannot proceed normally, membrane system and other lipid structure damage, eventually leading to plant death. It was generally slow for 1-3 weeks to get rid of the weed. The symptoms of weeds after application are as follows: the four-leaf stage buds are atrophied, leading to death. The leaves in the two-leaf stage changed little and remained green.
Rice has excellent selectivity and selectivity based on different metabolic rates. In rice, Cyhalofop-butyl can be rapidly degraded to an inactive diacid state of acetyl coenzyme A carboxylase, which is highly safe for rice. It is safe for stubble crops because of its rapid degradation in soil and typical paddy water.
1.Toxicity: has great toxicity to aquatic arthropods and avoids inflow into aquaculture sites. When mixed with some broad-leaved herbicides, it may exhibit antagonistic effect, showing that the efficacy of cyfluflux is reduced.
2.Storage and transportation:This product should be stored in a dry, cool, ventilated and rainproof place, away from fire and heat source. Keep out of the reach of children, non-professionals and animals. Do not store and transport with food, seeds, grain feed and other commodities.
