SUMMARY OF THE INVENTION The present invention provides a herbicidal compound of formula (I) wherein R is hydrogen, -COR12, -S (O) q (alkyl), generically substituted, alkyl, alkenyl, alkynyl, cycloalkyl or phenyl; and when a is 0, 1, 2 or 3, R may also be an optionally substituted alkylene or alkenylene group optionally substituted with an oxygen atom to form a 5-9 membered ring fused to the benzene ring, wherein the alkylene or alkenylene group is the benzene ring Is linked to position 3; R1 and R2 are halogen, cyano, thiocyanate, pentafluorothio, nitro, -NR5R6, -CO2R7, -CONR8R9, -C (R10) = NOR11, -COR12, -XR13, optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl or phenyl; and two adjacent R 1 or R 2 are optionally substituted, optionally substituted with one or two oxygen atoms, to form an alkylene or alkenylene group, which forms a 5- to 9-membered benzene ring-condensed ring. R3 and R4 are hydrogen, halogen, cyano, alkyl or alkoxy; or R 3 and R 4 are together alkylene; n is 0, 1, 2, 3 or 4; m is 0, 1, 2,3, 4 or 5; wherein m and n are at least 1; p is 0 or 1; and q is 0, 1 or 2, and relates to methods for preparing the compounds, compositions comprising the compounds, and the use of the compounds or compositions for controlling weeds, in particular, for controlling weeds in crop areas of cultivated plants or for inhibiting plant growth.
