Abstract: The present invention relates to new compounds of formula (I) wherein R1 to R3, U, V, W, Z and m have the significances given in the description, their use as antidotes, in herbicidal compositions for the control of weeds and plants in useful plant cultivation.

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 and to new active substances of the class of .beta.-halogenoethyl-silanes.The active substances in the new compositions respond to the formula ##STR1## wherein X is chlorine or bromine, Y represents chlorine or the radical --OR.sub.3, each of the radicals R.sub.1, R.sub.2 and R.sub.3 independently represent substituted or unsubstituted alkyl radicals, alkenyl, halogenalkenyl, alkynyl and cycloalkyl radicals, substituted or unsubstituted phenyl and benzyl radicals; one or more of the symbols R.sub.1, R.sub.2 and R.sub.3 can also represent the group --COR.sub.4, wherein R.sub.4 stands for an unsubstituted or substituted alkyl or alkenyl radical, a possible phenyl substituent may itself be substituted or not, for an alkynyl, alkoxyalkyl, alkoxycarbonylalkyl, or phenyl radical optionally substituted or for a heterocyclic radical; R.sub.
