Studies on Insecticidal Activity of Some Hydroxytriazene Derivatives
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.
