Karsil (also called erlüjixiancaoan) is an acylanilide herbicide, similar to propanil. It is potent against annual grasses and broadleaved weeds in celery, and a strong inhibitor of photosynthesis.[2] It is approved for use in China.[1]
When degraded by bacteria, karsil becomes 3,4-dichloroaniline and 3,3',4,4,'-tetrachloroazobenzene.[2] Karsil is theorised to form hydrogen bonds with the protein of an enzyme involved in the oxidation of water, creating its herbicidal potential, similar to diuron and atrazine.[3]
Karsil has been manufactured by Niagara Chemical Division.[4] If ingested, activated charcoal absorbs it.[5] Karsil is ten times as active as atrazine at the chloroplast level.[6]
