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

Abstract

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.
