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 1st, 3rd, and 7th 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. Maximum population reduction was noticed on the 3rd day after treatment.
