American Journal of Agricultural Economics v. 65, no. 4, p. 738-747615349Summary: The economic threshold concept is extended to a combination of two pest controls, insecticide and crop rotation, in a maize-soyabean farm model. Effect of risk attitudes on the optimal combination of controls is explored using a stochastic simulation with random crop prices, yields, and rootworm damage. Cropinsurance may cause a risk-averse farmer to adopt a riskier cropping programme. Reduced risk aversion causes the farmer to specialize in the more profitable maize crop. The insecticide and rotation thresholds both increase with reduced risk aversion. Depending on pest densities on individual fields, insecticide usemay increase orCollection: Reprints Collection
