A composition and a method for regulating the plant-metabolism, especially for promoting the abcission of citrus fruit and olives are disclosed, which use as active component a sulphonyl ester of the formula ##STR1## wherein R.sub.1 is an alkyl, alkenyl, phenyl naphthyl, diphenyl or thienyl radical,

Haloethylthienylsulphonates for the regulation of plant metabolism

Novel 2-amino-thiadiazole derivatives of the formula ##STR1## are described. In the formula, R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl; R.sub.2 is C.sub.1 -C.sub.4 alkyl; R.sub.3 is hydrogen or the group --CO--R.sub.4, in which R.sub.4 is alkoxyalkyl, C.sub.3 -C.sub.6 cycloalkyl, or is C.sub.2 -C.sub.4 alkenyl each of which is unsubstituted or mono- or polysubstituted by halogen, or is furyl, thienyl, pyridyl or phenyl, each of which is unsubstituted or mono- to tetrasubstituted by C.sub.1 -C.sub.4 alkyl, halogen, cyano, nitro, alkoxy, alkylthio, alkylsulfonyl or amino. These compounds possess useful bactericidal properties and can be used in particular for controlling phytopathogenic bacteria without damaging the treated cultivated plants. In comparison to aminothiadiazoles of the prior art, the compounds of this invention cause no tetratogenic side-effects.

3-(N-1,3,4-Thiadiazolyl-2)-aminoalkyl-alkyl-acrylates and use thereof as

An improved process for the preparation of 2-tert.-butyl-2-[1-phenoxy-1-(1H-azol-1-yl)]-methyl-ketales is disclosed, which process comprises reacting a 2-tert.-butyl-2-[1-phenoxy-1-halo]-methyl-ketale with a quaternary ammonium or phosphonium salt of an azole. The azoles used are 1H-1,2,4-triazole or 1H-imidazole.

Process for the preparation of 1H-azole derivatives

A composition and a method for regulating the plant-metabolism, especially for promoting the abscission of citrus fruit and olives are disclosed, which use as active component a sulfonyl ester of the formula ##STR1## WHEREIN R.sub.1 is an alkyl, alkenyl, phenyl, naphthyl, diphenyl or thienyl rest
