Cyhalofop-butyl Tech CAS NO.122008-85-9

Cyhalofop-butyl technical grade

Application:

Cyhalofop-Butyl is used for the synthesis of the formulation. It is an aryloxyphenoxypropionic acid herbicide. Selective herbicides in paddy fields is effective to stems and leaves, Pre-emergence treatment is ineffective. It mainly controls grass weeds such as Echinochloa crusgalli and Leptochloa chinensis.

【Usage】：Cyanide fluorine grass ester belong to aryloxy phenoxy propionic acid herbicide. It is the internal herbicide conductivity as same as other varieties. Absorbed by the plant's leaf and leaf sheath, phloem conduction, meristem zone, accumulation in plants to resist acetyl-coa carboxylase (ACCase), fatty acid synthesis had stopped, the growth of the cells divided unable to proceed normally, membrane system and other structures that contain fat, finally led to the death of plants.Weeds from cyanide fluorine grass ester is absorbed to die slowly, typically take 1-3 weeks.Symptoms are as follows: Atrophy of four-leaf stage shoots, leading to the death of weeds. Two-leaf stage older leaves have minimal change and remained green.
Mainly used for the control of important gramineous weeds.Cyhalofop-butyl is high efficient on moleplant seed, and have certain control effects on young barnyard grass. It can also control crabgrass, paspalum distichum,green bristlegrass, goosegrass, A.aequalis etc.It has no effect on sedge weeds and broad leaf weeds
