Abstract
Abstract Plant growth is regulated, e.g., inhibited or stimulated, by application to the plants or their habitat of effective amounts of at least one 5-azolyl-[a,d]-dibenzocycloheptene compound of the formula ##STR1## WHEREIN X is a --CH═CH-- or --CH 2 --CH 2 -- group, R is alkyl, alkoxycarbonyl or optionally substituted aryl, and Az is an azole radical of the formula ##STR2##

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
113 words
A method of regulating the growth of plants, which comprises applying to the plants or a habitat thereof an effective amount of a 5-azolyl-[a,d]-dibenzocycloheptene compound of the formula ##STR16## in which X is a --CH═CH-- or CH 2 --CH 2 -- group, R is alkyl of from 1 to 4 carbon atoms, alkoxycarbonyl of from 1 to 4 carbon atoms in the alkyl moiety, or phenyl wherein the phenyl radical may be substituted by up to 3 substituents selected from alkyl of from 1 to 4 carbon atoms, halogen, haloalkyl of up to 2 carbon atoms and up to 5 carbon atoms and Az is an azole radical selected from the formulas ##STR17##
Claim 2
Independent Claim
113 words
A method of regulating the growth of plants, which comprises applying to the plants or a habitat thereof an effective amount of a 5-azolyl-[a,d]-dibenzocycloheptene compound of the formula ##STR16## in which X is a --CH═CH-- or CH 2 --CH 2 -- group, R is alkyl of from 1 to 4 carbon atoms, alkoxycarbonyl of from 1 to 4 carbon atoms in the alkyl moiety, or phenyl wherein the phenyl radical may be substituted by up to 3 substituents selected from alkyl of from 1 to 4 carbon atoms, halogen, haloalkyl of up to 2 carbon atoms and up to 5 carbon atoms and Az is an azole radical selected from the formulas ##STR17##
