Integration of augmentative biocontrol with synthetic pesticides and other control methods for IPM – Challenges and prospects

The importance of augmentative biological control and chemical control, and the need and scope for integrating these, rather than dismissing them as incompatible, so as to create a win-win situation for both are highlighted. Besides the judicious use of chemicals and periodical releases of parasitoids/predators, other options such as insect-resistant transgenic crops, host plant resistance, botanical insecticides, sex pheromones, trap crops, pest resistance management, new product development, regulatory measures, etc., should also be exploited, as appropriate to a given situation, so as to develop an Integrated Pest Management (IPM) package. The practicality of such an IPM is explained, citing Bt cotton as an example. It is reiterated that IPM is the most prudent approach for sustainable crop production and protection with the major emphasis being laid on biological control and other eco-friendly methods as indicated by the latest global trend.
