Tested biopesticides were significantly superior over untreated check on 1 and 3-days after spray, but did not show any significant effect on the sap sucking pest population 7-days after spray. Of the biopesticides tested, A. indica seed kernel extract (5%) was most effective against whiteflies and jassids 1 and 3 days after the first and second sprays; however, after the third spray, the treatment schedule comprising A. indica oil followed by SL-NPV and later by A. indica seed kernel extract caused maximum reduction of jassids population. The treatment comprising A. indica leaf extract (10%) proved to be least effective against jassids and whiteflies. A. indica seed kernel extract (5%) was significantly more effective in causing the maximum population reduction of whiteflies and jassids after the three sprayings and A. indica oil (1%) application was the next in order of efficacy.
