The Delphi: Insecticide Use and Lint Yields. Beltwide Boll Weevil/Cotton Insect Management Programs: Appendix E

摘要

The Delphi, a method for systematic collection of information from experts, was modified to obtain biological data required for the economic analysis of boll weevil/cotton insect management programs. Cotton insect management and crop production experts provided detailed data regarding the insecticide use patterns and cotton lint yields they projected would result under each of five alternative insect management options, in 35 subregions of cotton production. Producers' average insect control costs under each program also were calculated from the information provided by the Delphi experts.
