The resistance of plants to environmental factors such drought is increased by treating the plants themselves, their seeds before sowing or the surrounding soil, before or after emergence of the plants, with compositions containing aliphatic epoxymonocarboxylic acids containing one to three epoxy groups and 6 to 22 carbon atoms or the salts, lower alkyl esters, lower polyhydroxyalkyl esters, amides, monoalkylamides and dialkylamides thereof as active ingredient.

Process for regulating or influencing the growth and metabolism of plants

Phenylpyridazines of the general formula: ##SPC1## In which Hal is a chlorine or bromine atom, R is a straight-chain or branched alkyl group containing 1 to 18 carbon atoms or a phenyl group, and X and Y separately are oxygen or sulphur, but not both oxygen, a process for their preparation and herbicidal compositions containing them.

3-Phenyl-6-halo-pyridazinyl thio-and dithio-carbonates

Phenylpyridazine compounds of the general formula ##SPC1## In which Hal is a chlorine or bromine atom and R is a straight-chain or branched alkyl group containing 2 to 20 carbon atoms when Hal is chlorine and 1 to 20 carbon atoms when Hal is bromine, or is the group --OR', wherein R' is an alkyl group of 1 to 18 carbon atoms which may be straight-chain or branched, and which have valuable herbicidal properties.
