Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
155 words
A method for controlling Avena fatua (wild oats) in cultures of cereal which comprises applying to cereal fields infested with the weed Avena fatua in post-emergence application a herbicidally effective amount of an ester of 1,2-diphenyl-cyclohex-1-ene-4-carboxylic acid of the formula ##STR16## wherein R is C 1 -C 7 alkyl, optionally substituted by halogen, C 1 -C 4 alkoxy, C 3 -C 8 cycloalkyl, by phenyl or phenoxy unsubstituted or substituted by chlorine, bromine, C 1 -C 4 alkyl or C 1 -C 4 alkoxy; C 3 -C 7 alkenyl, optionally substituted by chlorine, bromine or C 1 -C 4 alkyl; C 3 -C 6 cycloalkyl optionally substituted by chlorine, bromine or methyl; phenyl or benzyl unsubstituted or substituted by chlorine, bromine, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, nitro or tirfluoromethyl; and U and V are hydrogen, chlorine, bromine, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, nitro or trifluoromethyl.
