  • Patent number: 4347372
    Abstract: A process for protecting cultivated plants against aggressive agricultural chemicals is described in which oxime derivatives of the formula ##STR1## are used as antidotes. Either the cultivated area for the cultivated plants or the cultivated plants themselves or parts of the plant (seeds, tubers, stem parts and the like), as desired, can be treated with these oxime derivatives, which are used as a dressing.

  • Patent number: 4285959
    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.
