ABSTRACT

Arizona's pesticide use information system is a valuable tool for pest management research and extension. Recent advances in the pesticide use reporting system are presented. Active ingredients are quantified according to application frequencies, applied acreage, and product quantity per unit volume. Data are summarized to show patterns of use for categories of insecticides, herbicides, fungicides, defoliants, and plant growth regulators. Reported applications of agricultural chemicals are quantified to depict aspects of pest management practice.
