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.

Benzoxazolyl-glyoxylonitrile-2-oxime ether derivatives

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

Compounds of formula I ##STR1## WHEREIN R.sub.1 represents C.sub.1 -C.sub.4 -alkyl, alkyl(C.sub.1 -C.sub.4)-carbonyl or halogenoalkyl(C.sub.1 -C.sub.3)-carbonyl as well as salts thereof with organic and inorganic acids which are active against phytopathogenic microorganisms and in the regulation of plant growth.

Pyridine-4-carboxylic acid hydrazides for combatting phytopathogenic

Compounds of formula I ##STR1## wherein X represents chlorine, methyl of methoxy

Pyridine-4-carboxylic acid hydrazones for combatting phytopathogenic

Compounds of formula ##STR1## wherein X represents chlorine, bromine or iodine,

Amino containing isonicotinic acid derivatives

Carbamoyl oximes of the formula ##EQU1## their manufacture and fungicidal and virucidal activity are disclosed. In this formula R.sub.1 stand for alkylidene, aralkylidene or mono-, bi- or tricycloalkylidene and R.sub.2 stands for C.sub.8 to C.sub.14 alkyl, mono- or bicycloalkyl or cycloalkenyl.
