A field study was carried out to find out the effect of different botanical pesticides and a chemical pesticide on the sucking pests of cotton, Gossypium hirsutum. Insitu count of leafhopper (Amrasca devastans) and aphids (Aphis gossypii) were made prior to the pesticide application and on 1^st, 3^rd, and 7^th day after application of pesticides. Of the different botanicals used, neem seed kernel extract (5%) was found to be effective followed by Pongamia glabra seed kernel extract (5%), neem oil (3%) and Pongamia glabra oil (3%) against the sucking pests (Leafhopper and Aphids) of cotton.
