Arizona Department of Agriculture form 1080 data from 1995 to 1997 is reviewed and summarized. The data set is a unique and rich record of pesticide usage decisions. Regulatory anomalies make use of the data challenging. Results indicate a substantial general decline in the number of applications of pesticides. Active ingredient usage has not shown a similar general decrease. Contributing to the rise in active ingredient use per planted acre is an increase in application rates for many insecticides.
