Quinclorac

Chemical compound

Summary

Chemical compound

Quinclorac is an organic compound with the formula . A colorless solid, it is soluble in hydrocarbons and alcohols. The compound is the carboxylic acid of 3,7-dichloroquinoline.

Applications

Quinclorac is an herbicide used primarily to control crabgrass. It is found in some household herbicides for lawn use. Most lawn maintenance companies use the product for the control of annual grass weeds like crabgrass.

Quinclorac is a synthetic auxin. Heap considers it to also have a cellulose herbicide action, although some studies show quinclorac to have no cellulose action.

Regulation and registration

Quinclorac is not approved to use in the European Union due to toxicity concerns.

Resistance

Resistance to quinclorac is of concern in soybean cultivation. In rice, Graminaceous resistance is produced by the cytochrome enzyme CYP81A6.
