Studies on Insecticidal Activity of Some Hydroxytriazene Derivatives

Abstract

Nine hydroxytriazenes have been synthesized and screened for their insecticidal activity against one day oldDrosophila melanogasterMeig (Fruit fly). Out of all the nine compounds screened, 3-hydroxy-3-n-propyl-1-m-chlorophenyltriazene is the most active having LC50values 0.9847 ppm. The least active compound is 3-hydroxy -3-n-propyl-1-p-methylphenyltriazene, whose values are 16.52 ppm. In general, the LC50values range from 3.92 to 5.52 ppm.
