Integrated pest management (IPM) is the selection, integration and implementation of pest control based on known economic, ecological, and sociological consequences. IPM seeks maximum use of naturally occurring population control, including weather, disease agents, predators, and parasites. In addition, IPM utilizes various biological, physical and chemical means of control and habitat modification techniques in a compatible manner. Artificial controls are applied only as required to keep pests from surpassing intolerable levels. The presence of a pest species does not necessarily justify action for control and in fact tolerable levels are often desirable, providing food for beneficial organisms. The integration of control tactics such as resistant varieties, biological control agents, chemicals, and cultural practices into a "best-mix" for keeping all pests at acceptable levels, is the primary objective. To design, the "best-mix" requires a basic understanding of the ecological processes that exist in the rice ecosystem.
