| Abstract | The feasibility of Integrated Pest Management of eggplant fruit & shoot borer
(Leucinodes Orbonalis Gness) was examined, in a field experiment conducted during January
1996 to May 1996. Densities of eggplant fruit & shoot borer, other pests and predators were
determined in pesticide free and pesticide treated plots (simulated farmer's practice). A social
survey involving the eggplant farmers, extension agencies, scientists and local pesticide
dealers was also conducted to know the cmrent trend of pesticide use and related aspects.
The pesticide free plot had fewer pests and a much higher number and diversity of
predators than pesticide treated plot. A secondary pest out break of mite (Tetranchychus
cinnabainus) and thrips was observed in pesticide treated plot. Pesticides were found
ineffective against L. orbonalis and by and large they killed disproportionately predators. Most
farmers received information on pesticide use from the dealers, who were primarily
businessman. Conspicuous by the complete exclusion were research and extension program.
The extension agencies recommends the outdated insecticides with higher frequency but
farmers were using different insecticides with higher doses but less frequently. The local
pesticide retailers was found to be source of knowledge for majority of farmers even through
they had little knowledge of pesticide use and hazards. The health hazards were frequently
observed due to poor knowledge about method of handling and use of pesticides. Due to
intensive use of pesticides, residue of fenvalerate and endosulfan was found from samples of
45% local market. |
