Abstract
Abstract Plant-growth regulating compositions and methods having strong effects on plant growth, containing a heterocyclic sulfonium salt of the formula ##STR1## in which R is alkyl; substituted alkyl; alkenyl; alkynyl; cycloalkyl; or aralkyl which is optionally substituted in the aryl moiety; A - is one equivalent of an anion; and X is oxygen or the group N + R'R" A - or S + -R'" A - in which A - is identified as above; R' and R", which may be identical or different, are each alkyl of up to 6 carbon atoms; and R'" is defined as R or can be, together with R, an ethylene linkage.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
75 words
Plant-growth regulant composition containing from 0.1 to 95% of a heterocyclic sulfonium salt of the formula ##STR16## in which R is methyl; A - is one equivalent of an anion of a chlorine or methyl sulfate; and X is the group N + R'R"A - in which A - is identified as above; and R' and R", which may be identical or different, are each methyl; and at least one plant-growth regulatingly acceptable inert carrier.
Claim 2
Dependent Claim
75 words
Plant-growth regulant composition containing from 0.1 to 95% of a heterocyclic sulfonium salt of the formula ##STR16## in which R is methyl; A - is one equivalent of an anion of a chlorine or methyl sulfate; and X is the group N + R'R"A - in which A - is identified as above; and R' and R", which may be identical or different, are each methyl; and at least one plant-growth regulatingly acceptable inert carrier.
Claim 3
Dependent Claim
12 words
Composition as claimed in claim 1 wherein A - is a chlorine.
Claim 4
Dependent Claim
14 words
Composition as claimed in claim 1 wherein said heterocyclic sulfonium salt is 1-methylsulfonia-4-dimethylammonia-cyclohexane dimethosulfate.
Claim 5
Dependent Claim
14 words
Composition as claimed in claim 1 wherein said heterocyclic sulfonium salt is 1-methyl-sulfonia-4-dimethylammonia-cyclohexane dichloride.
Claim 6
Dependent Claim
76 words
Method of inhibiting the growth of plants which method comprises applying to the locus thereof an effective amount of a heterocyclic sulfonium salt of the formula ##STR17## in which R is methyl A - is one equivalent of an anion of a chlorine or methyl sulfate; and X is the group N + R'R" A - in which A - is identified as above; R' and R", which may be identical or different, are each methyl.
