Abstract: A simulation model of interaction between the boll weevil insect subsystem and the cotton plant subsystem is presented. Field experiments provide the basis for validation of the model. Pesticide control scheme is introduced, and optimal control is achieved by using a numerical nonlinear dynamic optimization technique. Results of sensitivity analysis with respect to price changes are provided. Optimal policy for a single producer calls for three applications. Timing is robust, but dosage levels are sensitive to price changes.
