Abstract

Ten insecticides were evaluated in field for the control of mango leafhoppers Idioscopus niveosparsus (Leth.), Idioscopus clypealis (Leth.) and Amritodus atkinsoni (Leth.) on 15-year-old Alphonso trees at Dryland Horticultural Farm, Kumbapur, UAS, Dharwad. New molecules lambda cyhalothrin (Karate 5 EC) and Imidacloprid (Confidor 200 SL) were highly effective recording least (0.03) population of mango leafhoppers upto 21 days after the spray, totally two sprays were required to manage the mango leafhoppers. Monocrotophos, cypermethrin, acephate and difenthiuron were the next best treatments (0.59 to 1.45 leafhopper/inflorescence) and were on par with one another. Fipronil and endosulfan were the least effective treatments (1.59 and 2.06 leafhopper/inflorescence) and were superior to untreated control which registered maximum population of 6.72 leafhoppers.
