With the ever- increasing population and escalating demand for food, scientists are toiling hard to enhance the production level through the introduction of new high yielding cultivars, effective cultural practices and adopting advanced technologies. Pesticides are one of the most essential inputs in modern agriculture for insuring food security particularly in the developing countries where population growth for exceed the agricultural growth. Among the various strategies adopted to combat pest of tomato, insecticides from the first line of defense. Most of the insecticides used on agriculture crop are based on quite limited number of chemically different classes and most important organic insecticides that are used against the pest on tomato and brinjal is belong to organophosphates. But the indiscriminate use of pesticides, in modern agriculture has led to various negative impacts on the environment. Some of the pesticides remain persistent (Recalcitrant) and move into the environment. The Tomato, Lycopersicon esculentum (Miller) and Solanum melongena are an important vegetables crop grown throughout the year in the India. However these vegetables crop suffers heavily from ravages of various insect pests and disease, which reduce not only the yield but also the quality of the fruits.The pesticidal / xenobiotic stress at high concentration of pesticides adversely affect the Chlorophyll Stability Index (CSI), Membrane Stability Index (MSI) and Relative Water Content (RWC).
