Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 64 words
A method of inhibiting the internodal growth of plants which comprises contacting the plants selected from the group consisting of crop plants, ornamental plants, and turf, with an effective growth inhibiting amount of a compound of the formula ##EQU3## wherein R is 5-pyrimidinyl; R 1 is isopropyl; R 2 is trifluoromethoxyphenyl, tetrafluoroethoxyphenyl or pentafluoroethoxyphenyl; X is hydroxy; and the nonphytotoxic acid addition salts thereof.
Claim 2
Independent Claim 64 words
A method of inhibiting the internodal growth of plants which comprises contacting the plants selected from the group consisting of crop plants, ornamental plants, and turf, with an effective growth inhibiting amount of a compound of the formula ##EQU3## wherein R is 5-pyrimidinyl; R 1 is isopropyl; R 2 is trifluoromethoxyphenyl, tetrafluoroethoxyphenyl or pentafluoroethoxyphenyl; X is hydroxy; and the nonphytotoxic acid addition salts thereof.
Claim 3
Dependent Claim 23 words
The method of claim 1 wherein the compound is applied at the rate of from about 0.125 to about 5 lbs. per acre.
Claim 4
Dependent Claim 23 words
The method of claim 1 wherein the compound is applied at the rate of from about 0.125 to about 2 lbs. per acre.
Claim 5
Dependent Claim 11 words
The method of claim 1 wherein the active compound is α-isopropyl-α-[p-(trifluoromethoxy)phenyl]-5-pyrimidinemethanol.
Claim 6
Dependent Claim 11 words
The method of claim 1 wherein the active compound is α-isopropyl-α-[p-(pentafluoroethoxy)phenyl]-5-pyrimidinemethanol.
Claim 7
Dependent Claim 11 words
The method of claim 1 wherein the active compound is α-[3,4-(difluoromethylenedioxy)phenyl]-α-isopropyl-5-pyrimidinemethanol.
Claim 8
Dependent Claim 61 words
The method of claim 1 wherein the growth-inhibiting compound is used in the form of a composition comprising an effective amount of a compound of the formula ##EQU4## wherein R is 5-pyrimidinyl; R 1 is isopropyl; R 2 is trifluoromethoxyphenyl, tetrafluoroethoxyphenyl, or pentafluoroethoxyphenyl; X is hydroxy; and the nonphytotoxic acid addition salts thereof, an agriculturally-acceptable inert carrier, and a dispersing agent.
Claim 9
Dependent Claim 48 words
A growth-inhibiting composition comprising an effective growth-inhibiting amount of a compound of the formula ##EQU5## wherein R is 5-pyrimidinyl; R 1 is isopropyl; R 2 is trifluoromethoxyphenyl, tetrafluoroethoxyphenyl, or pentafluoroethoxyphenyl; X is hydroxy; and the nonphytotoxic acid addition salts thereof, an agriculturally-acceptable inert carrier, and a dispersing agent.
Claim 10
Dependent Claim 48 words
A growth-inhibiting composition comprising an effective growth-inhibiting amount of a compound of the formula ##EQU5## wherein R is 5-pyrimidinyl; R 1 is isopropyl; R 2 is trifluoromethoxyphenyl, tetrafluoroethoxyphenyl, or pentafluoroethoxyphenyl; X is hydroxy; and the nonphytotoxic acid addition salts thereof, an agriculturally-acceptable inert carrier, and a dispersing agent.
Claim 11
Dependent Claim 12 words
A composition as defined in claim 8 wherein the compound is α-isopropyl-α[p-(trifluoromethoxy)phenyl]-5-pyrimidinemethanol
