Abstract:Economic analyses were conducted on fresh-market tomato plantings in 1992 and 1993 that compared the benefit of an integrated pest-management (IPM) program based on a registered Bacillus thuringiensis preparation with the current chemical-standard pesticide practices and an untreated control. The IPM program used three or four applications of B. thuringiensis as needed. The chemical-standard treatment consisted of seven to nine applications of methomyl and permethrin. The effect of each pesticide-use program on insect populations, fruit damage, yield, crop value, cost of control, and net profit was determined. The chemical-standard and IPM treatments reduced pest populations and damage, resulting in better yield and net profits as compared with the control treatment. In 1992, net profits were higher by ≍$500-1,000/ha in the IPM program as compared with the chemical-standard treatment. In 1993, the chemical-standard program performed slightly better by ≍$300Iha. However, given shipping prices over the past 5-yr period, the IPM approach would outperform the chemical-standard treatment in terms of net profit >80% of the time. In addition, the economic results from the IPM program are conservative because some significant benefits, such as a potential reduction in development of pesticide resistance, reduced soil compaction, less potential for damage to the environment, and less possibility of human health concerns, were not included.
