طريقة مبسطة لحساب النسبة المئوية للتنشيط و التآزر و التقوية للمواد المضافة لمبيدات الآفات

Abstract EN

The results of applying new method in calculating the percent of activation, potentiation and Synergism added on mortality percentage of the mixture Deltamethrin 2.5 % Ec + Ground nut oil) and the mixture components separately in controlling the 3th instar of larvae of Plodia interpunctella (Hubn.) , show that the Mean total mortality reached 58.2% which represents the mean mortality percentage of Deltamethring 18.95% and oil mortality percentage 12.19 % (Potentiation and Synergism percentage of oil which reached 27.05 % .

The results indicated that the ground nut oil exhibited a potentiation and synergism effect when mixed with Deltamethrin .

While the results of mixing deltamethrin with Piperonyl butoxide revealed that the Mean of total Mortality percentage reached 40.86 % which represents the total of Deltamethrin mortality percentage 27.% and Piperonyl butoxide mortality percentage zero % ( No Potentiation ) and Synergism effect of Piperonyl butoxide which reached 13.86%.
