Abstract
Abstract The invention relates to a method for controlling the relative stem growth of plants by applying to the foliage of the plants, or to soil containing seeds of the plants, a plant-growth-regulating amount of an imidazoisoindoledione or dihydroimidazoisoindoledione or an optical or stereo isomer thereof.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
121 words
A method for controlling the relative stem growth of plants comprising treating the plants with a compound of the formula: ##STR59##wherein X represents H, CH 3 , Cl, OCH 3 , SCH 3 or NO 2 ; R 1 and R 2 each represent alkyl C 1 -C 4 , provided that the sum of the carbon atoms in the groups represented by said R 1 and R 2 is 4 to 7, and when R 1 and R 2 are taken together with the carbon to which they are attached, they may represent cycloalkyl C 5 -C 6 optionally substituted with CH 3 ; in an amount sufficient to increase or reduce the relative stem length of the treated plant.
Claim 2
Independent Claim
121 words
A method for controlling the relative stem growth of plants comprising treating the plants with a compound of the formula: ##STR59##wherein X represents H, CH 3 , Cl, OCH 3 , SCH 3 or NO 2 ; R 1 and R 2 each represent alkyl C 1 -C 4 , provided that the sum of the carbon atoms in the groups represented by said R 1 and R 2 is 4 to 7, and when R 1 and R 2 are taken together with the carbon to which they are attached, they may represent cycloalkyl C 5 -C 6 optionally substituted with CH 3 ; in an amount sufficient to increase or reduce the relative stem length of the treated plant.
Claim 3
Dependent Claim
98 words
A method according to claim 1, for increasing the relative stem growth of plants comprising, applying to the foliage of the plant or the soil in which it is growing, from about 0.28 to 11.2 kg/hectare of a compound according to claim 1, wherein X is chloro, R 1 and R 2 each represent alkyl C 1 -C 4 provided that the sum of the carbon atoms represented thereby is 5 to 7, or when R 1 and R 2 are taken together with the carbon to which they are attached represent cycloalkyl C 5 -C 6 .
Claim 4
Dependent Claim
71 words
A method according to claim 2, wherein the compound has the formula: ##STR60##wherein R 1 and R 2 each represent alkyl C 1 -C 4 , provided that the sum of the carbon atoms represented by R 1 and R 2 is 5 to 7, or when R 1 and R 2 are taken together with the carbon to which they are attached they represent cycloalkyl C 5 -C 6 .
