The invention provides a method of reducing the feeding activity of insects on plants with the aid of 1,2,3-triazoles being unsubstituted in the 4- and 5-positions and bearing a phenyl moiety in the 1-position, fungicidal compositions comprising such triazoles and novel 1,2,3-triazoles.

Triazoles, and their use against insect pests

The present invention concerns novel pyrimidinyl phosphoric and thiophosphoric esters. ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are substituents, e.g. alkyl,

Pesticidal pyrimidinyl phosphorus esters

The present invention concerns novel N,N'-diphenyl-N-(N'-alkylcarbamoyl)formamidine derivatives of the formula: ##EQU1## wherein R.sub.1 is hydrogen or alkyl, R.sub.2 is alkyl and Ar.sub.1 and Ar.sub.2 are each phenyl or a substituted phenyl, which compounds are useful as herbicides.

N,N'-diphenyl-N-(N'-alkylcarbamoyl)formamidines

The present invention concerns novel 4-hydroxypyrimidine derivatives of the formula: ##SPC1## Wherein R.sub.1 is a substituent, e.g., alkyl, R.sub.2 is hydrogen or a substituent, e.g., alkyl R.sub.3 is amino unsubstituted or substituted by alkyl, a nitrogen heterocycle, alkoxy or alkylthio, which are used as intermediates in the production of useful insecticides.
