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.sup.- is one equivalent of an anion; and X is oxygen or the group N.sup.+ R'R" A.sup.- or S.sup.+ -R'" A.sup.- in which A.sup.- 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.
Claims9
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.sup.- is one equivalent of an anion of a chlorine or methyl sulfate;
- and
- X is the group N.sup.+ R'R"A.sup.- in which
- A.sup.- 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.
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.sup.- is one equivalent of an anion of a chlorine or methyl sulfate;
- and
- X is the group N.sup.+ R'R" A.sup.- in which
- A.sup.- is identified as above;
