    Abstract: Control of undesired plant growth comprises treating undesired plants and/or their environment with a herbicidally effective amt. of cyclohehene-1-aldehyde (I). In (I), R1 = CHO, 1,3-dioxolan-2-yl or CH(OR10)2; R2, R3 = H, or 1-4C alkyl or R2 + R3 = -CH2-; R4 = H, 1-4C alkyl or R11; R5 = H; R6, R7 = H or 1-4C alkyl or R6 + R7 = propylene opt. mono, di- or trisubstd. by 1-4C alkyl; R8 = H, 1-4C alkyl or OH; R9 = H, or 1-8C alkyl; R10 = 1-4C alkyl; R11 = H or silyl protecting gp. New cpds. (Ia), i.e. cpds. (I) where R2, R3 and R5-R8 = H, R4 = OR11, R9 = H or 1-8C alkyl; R10 = 1-4C alkyl) are also claimed. Known cpds. (I) are described in Planta Med. 1991, 344-346 and J. Org. Chem 55, 3004-3005 (1990) (isovelleral, isoisovelleral and corresp. hydroxy cpds). J. Chem Soc. Perkin Trans 1, 1990, 1901-1908 (1,3-dimethyl-2-cyclohexane- 1,2-dicarboxaldehyde) and Synth. Commun. 1981, 627-633 (6,6-dimethyl-2-cyclohexene -1,2-dicarbaldehyde). USE - Cpds. (I) can be used as such or as herbicidal compsns. (formulated conventionally) for pre- or post-emergence control of undesired plants, e.g. Chinese hemp, amaranth pigweed and goosefoot, in a wide variety of crops, e.g. cereals, rice, coffee, hops, potatoes, tomatoes, sugar cane and tobacco. Application is at 0.001-5 pref. 0.01-2 kg (I)/ha.

    Abstract: Acylamino-substituted isoxazoles or isothiazoles of the formula I in which X is oxygen or sulphur; R is optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl or phenyl; R is CN, CONH2, CSNH2, SCN or haloalkyl; R is hydrogen or optionally substituted alkyl or cycloalkyl; R is alkoxy, optionally substituted alkyl, cycloalkenyl, cycloalkyl, alkenyl or alkinyl, an optionally substituted 5- to 6-membered heterocyclic radical or optionally substituted phenyl; haloalkyl, alkoxy, haloalkoxy, alkylthio and/or haloalkylthio; and agriculturally utilisable salts of the isoxazole or isothiazole derivatives I with the exception of: 3-methyl-4-rhodano-5-trifluoroacetylamino-isoxazole, 3-methyl-4-rhodano-5-benzoylamino-isoxazole, 3-methyl-4-cyano-5-(2-furyl)-carbonylamino-isoxazole, 3-ethyl-4-cyano-5-(2-furyl)-carbonylamino-isoxazole, 3-methyl-4-cyano-5-benzoylamino-isothiazole, 3-methyl-4-carboxamido-5-acetylamino-isothiazole, 3-methyl-4-carboxamido-5-(4-chlorobenzoyl)-amino-isothiazole, 3-methyl-4-carboxamido-5-(2-chlorobenzoyl)-amino-isothiazole, 3-methyl-4-carboxamido-5-benzoylamino-isothiazole, 3-phenyl-4-cyano-5-benzoylamino-isoxazole, 3-phenyl-4-cyano-5-(4-chlorobenzoyl)-amino-isoxazole, 3-phenyl-4-cyano-5-(4-methylbenzoyl)-amino-isoxazole and 3-phenyl-4-cyano-5-propionylamino-isoxazole, compositions comprising the compounds I, and their use as herbicides.
