Preface This manual was prepared to supercede two earlier publications: "Apply Pesticides Correctly, A Guide for Private Applicators" and "Apply Pesticides Correctly, A Guide for Commercial Applicators." both published in 1974 by the U. S. Department of Agriculture and the Environmental Protection Agency. In contrast to these two prede- cessors, this manual attempts to do more than es- DATE. tablish a working threshold for those applicators seeking initial certification as provided by the Federal Insecticide, Fungicide and Rodenticide Act of 1972. OF This manual contains information that will allow you, the applicator, to satisfy the general require- ments in all states. As an applicator, however, you should keep in mind that each state has adopted rules establishing minimum requirementsOUT for certi- fication and recertification of applicators operating within its borders. BecauseIS certification does re- quire knowledge of specific situations among the various categories of pesticide application, be ad- vised to check carefully with your local agricultural extension agent to learn of your state's general and specific certification requirements. information: PUBLICATIONcurrent most THIS For http://extension.oregonstate.edu/catalog Applying Pesticides Correctly DATE.
