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.

[edit] 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.
[edit] 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]
