The results revealed that, Acetamiprid 20% SP @ 0.3 g/l was found to be most effective against leafhopper with higher per cent reduction of leafhopper population (83.06 per cent), followed by Imidacloprid 17.8 % SL @ 0.5 ml/l, Acephate 75 % SP @ 1 g/l, and Afidopyropen 50 DC @ 2ml /l which recorded 82.91, 77.48, and 76.59 per cent reduction in the pest population, respectively. The next best treatments were Azadirachtin 0.03% @ 2 ml/l (65.85%), Diafenthiuron 50% EC @ 1 ml/l (65.60%), Chlorfenapyr 10% EC @ 1 ml/l (56.98%) and fenazaquin 10% EC @ 2 ml/l (53.41%).
