Anyone applying pesticides “for hire” in Colorado must be a licensed commercial applicator in one or more of the 23 categories designated by the Colorado Department of Agriculture. Individuals seeking to be licensed in Colorado must pass the General test and at least one category where they will be making pesticide applications. Colorado Pesticide Applicator Study Guides are available to help prepare applicators to take certification tests. These study guides were prepared by the Colorado Environmental Pesticide Education Program (CEPEP) at CSU together with the Colorado Department of Agriculture Pesticide Program.  More information on the Colorado Department of Agriculture Pesticide Licensing Program can be found at the CEPEP website.

Manuals are for Individual sale only. Not for Resale.
