Determination of Factors that Contribute to Alasa Farm's Significantly Lower Pesticide Costs when Compared to the Area Average as Reported in Cornell's 1992 Fruit Business Summary

I have found that at Alasa Farms in my 1992 pesticide cost per acre are $120. The 1992 Cornell Fruit Business Summary shows the same pesticide costs as an average of 22 farms at $287. I want to determine why my pesticide costs are significantly lower and if the quality of Alasa apples is lower than the farms studied by Cornell. If the quality of Alasa IPM apples is similar to the others, than I would like to publish the results to show other growers where they might make changes in their pesticide program to reduce the amount of chemicals applied per acre.
