Regulatory Efficacy of Novel Insecticides Against Major Pests of Vegetables in Faisalabad, Pakistan

Abstract

Leucinodes orbonalis and Earias vittella/Earias insulana are major devastating pests of our summer vegetables especially brinjal and okra. Six insecticides viz. spinetoram 120 SC, spinosad 240 SC, bifenthrin 10 EC, cypermethrin 10 EC, chlorantraniliprol 20 SC and flubendiamide 480 SC were applied on brinjal and okra against these pests with five replications. Data was recorded after 24 hrs. 72 hrs. 7 and 10 days after spray application. Results indicated that all the insecticides gave significant control of both pests up to 72 hrs. of spray application. After this pest population was started to increase. In L. orbonalis spinetoram 120 SC (70 ml) gave maximum reduction 85.60 % followed by spinetoram 120 SC (50 ml) flubendiamide 480 SC and spinetoram 120 SC (40 ml) having 81.85, 65.25 and 63.57 %, respectively after 72 hrs of application. In E. vittella/E. insulana Spinetoram 120 SC (70 ml), Spinetoram 120 SC (50 ml), Spinosad 240 SC and Flubendiamide 480 SC gave maximum reduction 76.93, 74.32, 71.01 and 69.26 %, respectively. Bifenthrin 10 EC and cypermethrin 10 EC were least effective against both pests at all intervals and after 7 and 10 days intervals pests population was increased as compared to the previous intervals
