The invention pertains to certain oxadiazolinones of the formula: ##STR1## in which R represents an alkyl radical containing 1 to 4 carbon atoms and R.sub.1 represents an alkyl radical containing 2 to 4 carbon atoms, an alkoxy radical of which the alkyl part contains 1 to 4 carbon atoms, an alkylthio radical of which the alkyl part contains 1 to 4 carbon atoms, or trifluoromethyl, and to their preparation and the compositions in which they are present, which compounds and compositions have utility as nematocides, acaricides and insecticides.

Derivatives of alkoxy-5-phenyl-3 oxadiazoline-1,3,4 one-2, their

Oxadiazolinone derivatives of the formula: ##STR1## wherein R represents alkyl of 1 through 4 carbon atoms, R.sub.1 represents halogen, alkyl of 1 through 4 carbon atoms, alkoxy of 1 through 4 carbon atoms or alkylthio of 1 through 4 carbon atoms, and R.sub.2 represents hydrogen, halogen, alkyl of 1 through 4 carbon atoms, alkoxy of 1 through 4 carbon atoms or alkylthio of 1 through 4 carbon atoms, are useful as anthelmintics.

Anthelmintic oxadiazolinone derivatives

Phenylhydrazone derivatives of the formula: ##SPC1## Wherein R represents alkyl containing 1 to 4 carbon atoms, and two of the symbols R.sub.1, R.sub.2 and R.sub.3 represent a halogen atom and the third represents a halogen atom or a nitro radical, are new compounds possessing insecticidal and acaricidal properties.
