A compound of the formula: [Figure] (I) wherein R represents hydrogen; R1 represents: straight- or branched- chain alkyl, alkenyl or alkynyl having up to 6 carbon atoms, optionally substituted by one or more halogens; or cycloalkyl having from 3 to 6 carbon atoms, optionally bearing one or more substituents selected from the group consisting of R93, halogen and -CO2R96, wherein R93 and R96 are as defined below; or cycloalkenyl having from 3 to 6 carbon atoms, optionally beating one or more substituents selected from the group consisting of R93, halogen and -CO2R96, wherein R93 and R96 are as defined below; or an aryl or arallcyl group of the formula (R2)q-phenyl-(-CR93R94-)p-, wherein R2, q, p, R93 and R94 are as defined below; or a member selected from the group consisting of -CO2R93, -COR93, cyano, nitro, -NR93R94 and halogen, wherein R93 and R94 are as R95, -S(O)mR95, -SO2NR93R94, -CO2R93, -COR93, defined below; R2 represents: a member selected from the group consisting of nitro, cyano, halogen, -CONR93R94, -CSNR93R94, -OR95, C1-C3 alkyl substituted by -OR95; and -O(CH2)rOR97, wherein R93, R94, R95, R97, m and r are as defined below; n represents an integer from 1 to 5; Q represents C〓O; R93 and R94, which can be the same or different, each represents: hydrogen or straight- or branched- chain alkyl having up to 6 carbon atoms, optionally substituted by one or more halogens; R95 represents: straight- or branched- chain alkyl having up to 6 carbon atoms, optionally substituted by one or more halogens; R96 is as defined for R93 but does not represent hydrogen; R97 represents straight- or branched- chain alkyl having up to 4 carbon atoms, optionally substituted by one or more halogens; m represents zero, 1 or 2; q represents zero or an integer from 1 to 5; p represents zero or 1; r represents 1, 2 or 3; or an agriculturally acceptable salt thereof; with the provisos that: (1) when R1 is methyl, then (R2)n cannot be 4-fluoro; and (2) when R1 is -NH2, then (R2)n cannot be 4-bromo.
