Integrated Pest Management is a system which utilizes all suitable techniques and methods used as compatible a manner as possibly to maintain pest population at levels those causing economic injury. Basic features of IPM are-
1. utilizes two or more control techniques together in an integrated fashion.
2. to make maximum use of natural mortality factor.
3. applies specific control measures only as and when necessary.
4. determines how the life system of pest needs to modified to reduce its numbers to a tolerable level (economic threshold).
Control of the cabbage aphid in England was possible by IPM. At first systemic insecticides were applied as soil treatment so that the parasites and predators of the pest remain unharmed.
Limitations of IMP- 1. A large amount of site specific ecological information is necessary and that the management programme may be implemented in a coordinated fashion.
2. It must be implemented over a large area.
3. The forecast and predictive monitoring are related to weather variables.
4. Since computer technology assist faithfully in monitoring, the economic feasibility in a country like India is a matter of question.
