EB1789 Economic Analysis of Codling Moth Control Alternatives in Apple Orchards. E. R. Williamson, R. J. Folwell, A. Knight, and J. F. Howell. Codling moths can infest 90% of production if not stopped. While insecticides are mainstays in the orchardists' battle against this pest, pesticide resistance and consumer attitudes have led researchers to study other "softer" control methods. One such method is the Isomate-C type emitter which releases male attracting pheromone and disrupts the breeding cycle. Cost analysis, worksheets, and data tables offer an organized cost:benefit analysis. Published June 1994. 14 pages $1.00.
