5 phenoxy acid class aryloxycarboxylic 

aryloxycarboxylic phenoxy acid herbicides by the Hoechst company first developed in 1975 reported that diclofop has herbicidal activity, The Dow Chemical Company in 1976 found a spirit of topiramate CFC grass, then developed a number of varieties. 

- Rapidly absorbed by plant leaves, in the symplast in the transmission to the bud meristem. 
- Acting on acetyl coenzyme A carboxylase, thus inhibiting fatty acid synthesis. 
- Selectivity is caused by the degradation of metabolic differences in drug resistance in plants can be rapidly degraded into inactive substances. 
- To increase plant aromatic phenoxy acid herbicides oxygen absorption, these agents are ester herbicide products, and not acid, decomposition of plants to absorb quickly into the active acid. 
- As stem treatment agent for use in broadleaf crops, annual and perennial Field Control in the weeds. 
- Aryloxycarboxylic phenoxy acid herbicides in the efficacy of temperature and soil moisture influenced. In the low temperature, soil moisture is poor spraying, weeding ineffective; in high temperature, soil moisture is good, vigorous growth of weeds when spraying, weeding effect. 

 application of crop 
- Broad-leaved crops, leafy vegetables and apples, grapes, etc. 
 Control in Object

 Note 
- (1) sensitive to grass crops, do not spray when spraying nearby rice, corn, barley, wheat and other cereal crops. 
- (2) Spray should be uniform, weed spray the whole plant. Rainfall within 2 hours after spraying efficacy of little effect. Soil drying, weed growth is slow, the amount may be increased. 
- (3) in the dry weather conditions, crop injury leaves sometimes, but leaves no injury, no effect on yield.

 Note 
- (1) air humidity and soil moisture is high, stability is conducive to killing weeds absorption, transport, efficacy easy to play. Spraying under high temperature and drought, weeds, stems and leaves can not fully absorb the agents, efficacy will be to a certain extent, the dosage should be increased at this time.

- (3) Wei Pa Barnyardgrass Control in Rice, the daughter and other son, mu 6.9% 20-25 ml of concentrated emulsion 
 Note 
- (1) can not be used for barley, oats, corn, sorghum field weeding. Can not Control in bluegrass and broadleaf weed. 
- (2) The application of Wei Pa rice fields after the rice leaves may be a "steadily yellow" phenomenon, usually 2-3 weeks after the drug elimination, does not affect production.
