A compound that, on administration, must undergo chemical conversion by biochemical (enzymatic), chemical (possibly following an enzymatic step), or physical (e.g. photochemical) activation processes before becoming the pharmacologically active herbicide for which it is a proherbicide.

| carfentrazone-ethyl | An ethyl ester resulting from the formal condensation of the carboxy group of 2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-3-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-4-fluorophenyl}propanoic acid with ethanol. | ethyl 2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-3-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-4-fluorophenyl}propanoate |
| chlorimuron ethyl | An ethyl ester resulting from the formal condensation of the carboxy group of chlorimuron with ethanol. A proherbicide for chloimuron, it is used as herbicide for the control of broad-leaved weeds in peanuts, soya beans, and other crops. | chlorimuron-ethyl |
| haloxyfop-P-methyl | A methyl 2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoate that has R configuration. It is a proherbicide (by hydrolysis of the methyl ester) for the herbicide haloxyfop-P, the most active enantiomer of the racemic herbicide haloxyfop. | haloxyfop-P-methyl |
| isoxaflutole | A member of the class of isoxazoles that is 1,2-oxazole substituted by a 2-(methanesulfonyl)-4-(trifluoromethyl)benzoyl group and a cyclopropyl group at positions 4 and 5, respectively. It is a 4-hydroxyphenylpyruvate dioxygenase inhibitor which is used as a herbicide for weed control in maize and sugarcane. | isoxaflutole |
| pinoxaden | A pyrazolooxadiazepine that is 7-oxo-1,2,4,5-tetrahydro-7H-pyrazolo[1,2-d][1,4,5]oxadiazepin which is substituted at positions 8 and 9 by 2,6-diethyl-4-methylphenyl and pivaloyloxy groups, respectively. A pro-herbicide (by hydrolysis of the pivalate ester to give the corresponding enol), it is used for control of grass weeds in cereal crops. | pinoxaden |
| triflusulfuron-methyl | A methyl ester resulting from the formal condensation of the carboxy group of triflusulfuron with methanol. A proherbicide for triflusulfuron. | triflusulfuron-methyl |
