This report examines the economic implications of losing chlordimeform use on cotton and considers chlordimeform's role in managing the resistance of bollworms and tobacco budworms to synthetic pyrethroids. It estimates changes in prices, production, acreage, consumer expenditures, aggregate producer returns, regional crop effects, and returns to users and nonusers of chlordimeform and pyrethroids. The report bases the economic effects on the estimates and views of the chlordimeform assessment team of the National Agricultural Pesticide Impact Assessment Program. This report also examines the effects on deficiency payments and the implications for pesticide benefit assessments. (YLB)
