Comparative efficacy of insecticides and plant extracts to manage Bemisia tabaci (Genn.) and tomato leaf curl virus disease

Muhammad Jahanzaib

Abstract


Tomato (Lycopersiconesculentum) is most important vegetable crop of Pakistan. It is attacked by many biotic and abiotic diseases. Among the viral disease tomato leaf curl virus disease (TLCVD) is most important disease that causes heavy yield losses. Under natural field conditions, TLCVD is transmitted by Bemisia tabaci. Comparative efficacy of insecticides and plant extracts to manage Bemisia tabaci (Genn.) and tomato leaf curl virus disease was studied under natural field conditions. Three insecticides (acetamaprid, imidacloprid and diafenthiuron) and three plant extracts (neem, garlic and onion) were sprayed. One treatment of distilled water was sprayed and considered as control. The results showed that among the insecticides,acetamaprid was most effective and neem among plant extracts was most effective. The comparative efficacy showed that insecticides manage the whitefly population more effectively than the plant extracts. Key Words: Tomato, whitefly population, insecticides, plant extracts, management.
