Studies on Insecticidal Activity of Some Hydroxytriazene Derivatives

Abstract

Nine hydroxytriazenes have been synthesized and screened for their insecticidal activity against one day old Drosophila melanogaster Meig (Fruit fly). Out of all the nine compounds screened, 3-hydroxy-3-n-propyl-1-m-chlorophenyltriazene is the most active having LC₅₀ values 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 LC₅₀ values range from 3.92 to 5.52 ppm.
