Seed treatment with Imidacloprid 70 WS @ 5 g/kg seed followed by dimethoate 30 Ec @ 0.03 percent, endosulfan 35 Ec @ 0.05 percent, quinalphos 25 Ec @ 0.05 percent and fenvalerate 20 Ec @ 0.015 percent recorded lowest aphid and jassid population. Brinjal or eggplant, Solanum melongena L. is grown throughout the country. Often described as a poor man's vegetable because it is popular amongst small scale farmers and low income consumers. Brinjal is grown on nearly 550,000 hectares in India, making country the second largest producer after China with a 26 percent world production share. Brinjal crop suffers heavily due to infestation of sucking pests and shoot and fruit borer. Aphid (Aphis gossypii Glover), Jassid (Amrasca biguttula biguttula Ishida) and white fly (Bemisia tabaci Gennadius) suck the cell sap and prohibit the normal crop growth. Beside direct damage, the sucking pests acts as vector for virus borne diseases. Use of chemical pesticides for management of these pests became a part of modern agricultural practices and their consumption has increased remarkedly. Due to irrational use they cause serious health hazards and environmental problems in developing countries including India. In view of shorter interval in the picking of brinjal fruits, there are always chances of persistance toxic residues on/in fruits. Chemical pesticide results in destruction of beneficial organisms, flora and fauna (Korsak and Sato, 1977). Cost effective crop production requires combination of optimum use of chemicals and non-chemical techniques of pest management. Integrated pest management in recent years has gained importance to overcome these problems. Present studies were undertaken to evaluate the efficacy of different bio-insecticides and bioagent for the management of aphid and jassid population infesting brinjal crop.
