An expert system,QSOY, was developed to determine to use insecticide against corn earworm (Helicoverpa zea) on soybean crops.Spray application thresholds are modeled based on general knowledge from agricultural extension publications, modified by knowledge obtained from interviews with extension entomology specialists and entomology researchers, and from judgments made by specialists on prototypical scenarios.The user is asked to supply information concerning the soybean field, the environmental conditions and the results of sampling for corn earworm larvae. 1 This report describes the process of knowledge acquisition used, the logic of the system and the way in which the system interacts with the user.The expert system development tool, ARITY/EXPERT is critically evaluated.
