Insecticidal

The present invention provides a method of preventing plants, such as fruit, vegetables etc. from damage by frost. The method consists in treating the said plants, before outbreak of frost, with an effective amount of a hydroxamic acid derivative of formula ##STR1## wherein R.sub.1 is alkyl or cycloalkyl,

Method of preventing plants from damage by frost

Aniline derivatives of the formula ##STR1## wherein R is hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkyl substituted by C.sub.1 -C.sub.2 -alkoxy are produced by reacting a N-(3-pent-2-enyl)-derivative of morpholine, piperidine or pyrrolidine with acrolein in the presence of an inert, aprotic solvent or in the absence of a solvent and heating the reaction product obtained to 100.degree.-400.degree.

Process for the production of (substituted) 2,6-dimethylanilines

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.

Pyridinium-s-triazines for regulating plant growth

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.
