| Abstract: | The Regional Economic Threshold concept is introduced. A model of pest control decisionmaking is generalized to permit choice of materials, timing, number of applications, and dosage rates. Constraints on the maximum dose alter the model and solutions. An experiment is performed to generate data for estimating both the efficacy of insecticides and the damage prevented. Simulating nonlinear systems, a computer program calculates optimal solutions and the sensitivity of the solutions to various relative prices. Losses from legal maximum dosage constraints are calculated, as well as potential benefits to growers' profits from applying the results of this research. |
