Overview

Acetochlor is an herbicide developed by Monsanto and Zeneca. It is a member of the class of herbicides known as chloroacetanilides. Its mode of action is elongase inhibition, and inhibition of geranylgeranyl pyrophosphate (GGPP) cyclisation enzymes, part of the gibberellin pathway.

Uses

It is marketed as an emulsifiable concentrate containing 36.7% of active ingredient. It is homologuated for pre-emergence application or for pre-planting application with soil incorporation, in corn (maize) at 5 litres / hectare (183.5g / hectare of a.i.)[2] and includes the trade names Acenit, Guardian, Harness, Relay, Sacemid, Surpass, Top-Hand, Trophy and Winner.

It is used to control weeds in corn, and is particularly useful as a replacement for atrazine in the case of some important weeds.


Safety

Acetochlor has been classified as a probable human carcinogen;[1] the conditions of registration ensure that acetochlor will pose a negligible risk to human health and the environment.[3]
