Abstract

Banana is a very popular and healthy fruit of India. Its utility and usefulness in our dietary schedule hardly requires any explanation because of its coloric value (67-137 Calories per 100 gm), vitamins (A,B,C & D) and minerals (Calcium, Phosphorus, Potash and iron). India is the largest banana producer in the world with 29, 124, 000 tonnes production annually. In India, Bihar is the sixth largest state in banana production. Out of various insect pests of banana, root weevil (Cosmopolites Sordidus Germ) is the most serious insect pest in Bihar. As a result of heavy infestation, plants weaken and yield decreases. Present investigation was carried out to evaluate the efficacy of application of granular insecticides against root weevil of banana and it was observed that the application of carbofuran and phorate minimized banana infestation by Cosmopolites Sordidus and enhanced the yield of banana.
