This report provides information on (1) pesticide production difficulties in 1974 and 1975 and their effects on pesticide supplies, and (2) pesticide demand estimates for the same years. Producers that accounted for about 75 percent of the basic farm pesticide production in 1971 were surveyed. Regional pesticide distributors covering most of the United States were also contacted for information on pesticide distribution and local availability. Many pesticide producers had difficulty achieving planned output for some pesticides in 1974. Output of about half of the pesticides produced fell below producers' goals, and overall production was about 10 percent below planned output. At the same time, the demand for pesticides increased an estimated 15 percent in 1974 over 1973. Thus, there was a tight supply demand situation with serious shortages of some products. The situation for 1975 is substantially improved with a 10-percent increase in production, but demand is holding at about Iast year's levels. Supplies of most pesticides should be adequate, or nearly so, in 1975. Additional production capacity should be on stream, and raw material shortages should have a smaller impact in 1976.
