Simulation models are synonymous with the application of the systems approach in pest management and help to formulate
decision support tools for an effective decision-making. A study was undertaken to improve our earlier work on simulation
of rice leaf folder (Cnaphalocrocis medinalis) damage and to develop decision support tools for its management.
Currently, the leaf folder damage on Pusa Basmati1 rice was simulated with data sets generated in two field experiments
during the rainy season 2008 and 2009. Simulated yields and total dry matter in different treatments over the experiments
were close to their observed counterparts, indicating an appropriate validation of the leaf folder damage mechanisms on
Pusa Basmati1 rice. The leaf folder economic injury levels were simulated based on control expenditure on application of
cartap hydrochloride 50SP and quinalphos 25SC, and market price of Pusa Basamti1. The simulated economic injury
levels of the leaf folder were more precise than that simulated in our previous study. Likewise, iso-loss curves represented
combinations of crop age and the leaf folder damage that resulted in a similar yield loss. These decision support tools
would facilitate accurate monitoring of the leaf folder damage to ensure judicious pesticide application.
