Abstract: The present invention relates to novel cyclohexane-1,3-dione derivatives of formula (I) useful as herbicides and plant-growth regulants. ##STR1## wherein, X is selected from the group consisting of hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.2 -C.sub.6 alkoxy, halogen, C.sub.1 -C.sub.6 haloalkyl, nitro, cyano, C.sub.1 -C.sub.6 alkylthio, C.sub.1 -C.sub.6 alkylsulfinyl, C.sub.1 -C.sub.6 alkylsulfonyl, sulfamoyl, N-(C.sub.1 -C.sub.6 alkyl) sulfamoyl and N,N-di(C.sub.1 -C.sub.6 alkyl) sulfamoyl group;(X)n represents number of X substituents which may be the same or different on benzene ring, where n is 1, 2 or 3.Also, cyclohexyl moiety, one of the substituents on benzofuran ring, is substituted at 4, 5, 6 or 7 position. The (X)n can't be filled only with hydrogens and the (X)n can substitute position where cyclohexyl moiety is not substituted;R.sup.1 is selected from hydrogen and C.sub.1 -C.sub.4 alkyl group;R.sup.2 is selected from C.sub.1 -C.sub.6 alkyl, C.sub.2 -C.sub.6 alkenyl and C.sub.2 -C.sub.

Abstract: The present invention relates to novel quinolinyloxadiazole derivatives of the following formula (I) having processes for their preparation and their use as herbicides and plant growth regulants, especially their use in the selective kill and control of barnyardgrass in the presence of rice. ##STR1## wherein, A and B are selected from the group consisting of hydrogen, halogen and C.sub.1 -C.sub.3 lower alkyl;R is a C.sub.3 -C.sub.4 alkyl or cycloalkyl, phenyl, pyridyl, benzyl, phenoxyalkyl or phenylthioalkyl, and aromatic groups in these radicals are optionally substituted with 1.about.3 substituents selected from the group consisting of halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylthio C.sub.2 -C.sub.6 alkoxyalkyl and an anolog thereof.
