Content
Getting
Quinmerac is synthesized by the reaction of 7-chloro-3,8-dimethylquinoline with N- bromosuccinimide in the presence of sulfuric and hydrochloric acids [2] .
Use
Quinmerak is a soil herbicide that is effective against such complex weeds as a cleaver , Veronica, and Yasnotka . Used in the cultivation of cereals, rapeseed and sugar beets [3] . Quinmerak is a synthetic auxin that activates ACC synthase. Thus, it comes to enrichment of plant tissue with the hormone abscisic acid . It causes leaf fall, inhibition of root growth and increased transpiration, which in total leads to the death of plants [4] .
Statement
In Germany, Austria and other EU countries, quinmerak is permitted as an active ingredient in plant protection products, but this herbicide is banned in Switzerland [5] .
