(+/–)-Diclofop is a chiral herbicide that belongs to the chemical class of chiral aryloxyphenoxypropionate compounds. The actual herbicidal active ingredient― carboxylic acid, is released after application through hydrolysis of the ester. It is absorbed mainly through leaves and inhibits the biosynthesis of fatty acids by suppressing the activity of acetyl CoA carboxylase (ACCase). It is used for the post-emergence control of wild oats, wild millets, and other annual grass weeds commonly occurring in wheat, barley, rye, red fescue, and broad-leaved crops.
It was included on 1st June 2011 in Annex I of Directive 91/414/EEC by the European Commission Directive 2011/45/EU. It is authorized for use under EC Regulation No 1107/2009, as per the Commission Implementing Regulation (EU) No 540/2011, however it is a candidate for substitution.

Enantioselective oxidative stress and toxin release from Microcystis aeruginosa after exposure to the chiral herbicide diclofop acid were investigated. Racemic diclofop acid, R-diclofop acid and S-diclofop acid induced reactive oxygen species (ROS) generation, increased the concentration of malondialdehyde (MDA), enhanced
