    Abstract: The present invention relates to new compositions and methods for the regulation of plant growth, especially for fruit abscission, acceleration of ripening and latex discharge of rubber trees, and to new active substances of the class of .beta.-halogenoethylsilanes.The new active substances in the new composition corresponding to the formula ##STR1## wherein X is chlorine or bromine, A represents a radical --SR.sub.1, --NR.sub.2 R.sub.3, --OR.sub.4, --CH.dbd.CH.sub.2 or --CH.sub.2 --CH.sub.2 --X, B and C each independently represent --CH.sub.3, --CH.dbd.CH.sub.2 or --CH.sub.2 --CH.sub.2 --X, the symbols R.sub.1, R.sub.3 and R.sub.4 representing substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl or benzyl radicals, R.sub.2 denoting hydrogen or the same as R.sub.3, whereby R.sub.2 and R.sub.3 together with the adjacent nitrogen atom can also form a saturated or unsaturated ring system, and R.sub.4 can furthermore represent the group --COR.sub.5, whereby R.sub.5 stands for alkyl, alkenyl, alkynyl, halogenoalk(en)yl, substituted or unsubstituted phenylalk(en)yl, alkoxyalkyl, alkoxycarbonylalkyl, benzoylalkyl, cycloalkylalkyl, for substituted or unsubstituted phenyl or for a 5- or 6-membered heterocyclic radical.

    Abstract: 2-Pyridinium-s-triazine salts of the formula ##STR1## wherein R.sub.1 represents unsubstituted or substituted alkyl of from 1 to 12 carbon atoms, alkenyl or haloalkenyl, R.sub.2 and R.sub.3 independently represent hydrogen, lower alkyl or haloalkyl and X.sup..crclbar. is the anion of an inorganic or organic acid. These salts are growth regulating agents especially for defoliation and desiccation of crop plants in order to facilitate harvesting. They may also be used as post-emergent herbicides.

    Abstract: The present invention relates to new compositions and methods for the regulation of plant growth, especially for fruit and leaf abscission, acceleration of ripening and latex discharge in rubber trees and to new active substances of the class of .beta.-halogenoethyl-silanes.The active substances of the new compositions correspond to the formula ##STR1## wherein X is chlorine or bromine, A represents a radical --SR.sub.1 or --NR.sub.2 R.sub.3, B represents a radical --SR.sub.1, --NR.sub.2 R.sub.3 or --OR.sub.4, and C represents a radical --SR.sub.1, --NR.sub.2 R.sub.3, --OR.sub.4 or the methyl or benzyl group. The symbols R.sub.1 to R.sub.4 are chosen from substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl and benzyl groups, R.sub.2 can also be hydrogen and R.sub.2 together with R.sub.3 and the adjacent nitrogen can form a heterocyclic ring system.
