Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 146 words
A method of inhibiting the growth of suckers on tobacco plants which comprises applying to the tobacco plants an effective amount of a compound of the formula: ##STR58## wherein R 1 and R 2 are each independently selected from the group consisting of: (a) hydrogen, (b) lower alkyl, (c) halo-substituted-lower alkyl, (d) lower alkenyl, (e) alkoxy-lower alkyl, and (f) monocycloalkyl-lower alkyl, with the proviso that only one of R 1 and R 2 can be branched lower alkyl or branched lower alkenyl; wherein R 3 is selected from the group consisting of: (a) halo, (b) lower alkyl, (c) halo-substituted-lower alkyl, (d) methylsulfonyl, and (e) sulfanilamide; with the proviso that R 1 and R 2 cannot both be hydrogen and that one of R 1 and R 2 may only be hydrogen when: (a) R 2 is alkoxy-lower alkyl, or (b) R 3 is halo-substituted lower alkyl.
Claim 2
Independent Claim 146 words
A method of inhibiting the growth of suckers on tobacco plants which comprises applying to the tobacco plants an effective amount of a compound of the formula: ##STR58## wherein R 1 and R 2 are each independently selected from the group consisting of: (a) hydrogen, (b) lower alkyl, (c) halo-substituted-lower alkyl, (d) lower alkenyl, (e) alkoxy-lower alkyl, and (f) monocycloalkyl-lower alkyl, with the proviso that only one of R 1 and R 2 can be branched lower alkyl or branched lower alkenyl; wherein R 3 is selected from the group consisting of: (a) halo, (b) lower alkyl, (c) halo-substituted-lower alkyl, (d) methylsulfonyl, and (e) sulfanilamide; with the proviso that R 1 and R 2 cannot both be hydrogen and that one of R 1 and R 2 may only be hydrogen when: (a) R 2 is alkoxy-lower alkyl, or (b) R 3 is halo-substituted lower alkyl.
Claim 3
Dependent Claim 14 words
The method of claim 1, wherein the compound is contained in an aqueous emulsion.
Claim 4
Dependent Claim 32 words
The method of claim 1, further comprised of applying in admixture with the compound between about 0.33 and about 3 parts by weight of surfactant per part by weight of the compound.
Claim 5
Independent Claim 104 words
A method of inhibiting the growth of suckers on tobacco plants which comprises applying to the tobacco plants an effective amount of a compound of the formula: ##STR59## wherein R 1 and R 2 are each independently selected from the group consisting of: (a) lower alkyl, (b) halo-substituted lower alkyl, (c) lower alkenyl, (d) alkoxy-lower alkyl, and (e) monocycloalkyl-lower alkyl, with the proviso that only one of R 1 and R 2 can be branched lower alkyl or branched lower alkenyl; wherein R 3 is selected from the group consisting of: (a) halo, (b) lower alkyl, (c) halo-substituted-lower alkyl, (d) methylsulfonyl, and (e) sulfanilamide.
Claim 6
Independent Claim 104 words
A method of inhibiting the growth of suckers on tobacco plants which comprises applying to the tobacco plants an effective amount of a compound of the formula: ##STR59## wherein R 1 and R 2 are each independently selected from the group consisting of: (a) lower alkyl, (b) halo-substituted lower alkyl, (c) lower alkenyl, (d) alkoxy-lower alkyl, and (e) monocycloalkyl-lower alkyl, with the proviso that only one of R 1 and R 2 can be branched lower alkyl or branched lower alkenyl; wherein R 3 is selected from the group consisting of: (a) halo, (b) lower alkyl, (c) halo-substituted-lower alkyl, (d) methylsulfonyl, and (e) sulfanilamide.
Claim 7
Dependent Claim 47 words
The method of claim 4, wherein R 1 and R 2 are independently selected from the group consisting of: (a) lower alkyl, (b) halo-substituted lower alkyl, (c) monocycloalkyl-lower alkyl; and R 3 is selected from the group consisting of: (a) lower alkyl, and (b) halo-substituted lower alkyl.
