    The inefficiency of pesticide application has become a serious economic and environmental problem. Improving application efficiency requires a better understanding of the application process. The transfer of dose from spray tank to pest target involves a large set of physical and biological factors. Investigating such a complex system experimentally is extremely laborious and costly. A model is described that allows investigation of the biological consequences of altering the application parameters for foliar applied insecticides (in this case, the bacterial insecticide Bacillus thuringiensis var. Kurstaki when used against the diamondback moth (Plutella xylostella L.) with cabbage as the substrate). Parameters input into the model include the frequency distribution of droplet size, spatial distribution of the deposit, the subsequent degradation of the deposit by environmental factors, and toxicological effects against the target pest. Possible applications of the model are discussed, as are some preliminary results.
