Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A herbicidal composition comprising an inert carrier and, as an essential active ingredient, in a quantity toxic to weeds, a compound of the formula ##STR11## wherein R 1 is selected from the group consisting of alkyl of up to 4 carbon atoms, lower alkenyl, lower chloroalkyl, trifluoromethyl, lower alkoxy, lower alkylthio, lower alkylsulfonyl and lower alkylsulfinyl; and R 2 is selected from the group consisting of lower alkyl, lower alkenyl, lower chloroalkyl, lower bromoalkyl and ##STR12## wherein R 3 and R 4 are each selected from the group consisting of hydrogen and alkyl of up to 3 carbon atoms.
Claim 2
Dependent Claim
99 words
A herbicidal composition comprising an inert carrier and, as an essential active ingredient, in a quantity toxic to weeds, a compound of the formula ##STR11## wherein R 1 is selected from the group consisting of alkyl of up to 4 carbon atoms, lower alkenyl, lower chloroalkyl, trifluoromethyl, lower alkoxy, lower alkylthio, lower alkylsulfonyl and lower alkylsulfinyl; and R 2 is selected from the group consisting of lower alkyl, lower alkenyl, lower chloroalkyl, lower bromoalkyl and ##STR12## wherein R 3 and R 4 are each selected from the group consisting of hydrogen and alkyl of up to 3 carbon atoms.
