Pesticides Registered in Colorado

The list of pesticides registered for use in Colorado changes regularly. You may want to know if pesticides you intend to use are Restricted Use Products (RUPs) to determine whether you need a certain type of pesticide applicator license. The following links provide information about pesticide registration.

Licensing and Examination Guide

All people in Colorado who use pesticides are regulated by the Colorado Department of Agriculture. Learn more about certification from the following sources:

Regulation and Inspection

The Colorado Department of Agriculture (CDA) Division of Plant Industry (DPI) Pesticides Program has the following responsibilities:

  • To regulate pesticide distribution and use in the state to prevent adverse effects on the individual and the environment.
  • To inspect the sales of restricted use pesticides (RUPs) and the use, storage and disposal of pesticides and certain devices for pesticide application.

Fumigation Management Plan

Information on Fumigation Management Plans can be found at CDA’s website.

Pollinator Protection

Pesticides are an important part of an Integrated Pest Management (IPM) plan. The areas treated are often shared by pollinators like bees, butterflies, wasps, and some birds and bats. Pollinators are essential in the survival and propagation of many flowering plants both in farms and on the urban landscape.

How to Reduce Pesticide Risk for Honey Bees

  • Use Integrated Pest Management (IPM). IPM includes a combination of cultural, mechanical, biological organisms and pesticides. If pests cannot be managed by a combination of IPM strategies, a pesticide application may be necessary.
  • Follow the pesticide label. Many labels contain bee hazard statements under the PRECAUTIONARY STATEMENTS.
  • Communicate with beekeepers near sites that require pesticide application. FieldWatch/DriftWatch are useful tools to help identify hive locations.
  • Register for FieldWatch to locate hives.
  • Know if there is an established RT25 for the pesticide you want to use. This is the residual time for 25% mortality of a hive based on a foliar application. It is assumed that if no more than 25% of the hive is affected, the hive will recover. More information and the data available for active ingredients can be found HERE.


CSU Extension Water Quality Programs

Water quality protection is an important responsibility of any pesticide applicator, private, public, or commercial. Colorado State University’s Water Quality Programs has many resources to help you protect water from agricultural chemicals, including links, presentations, and publications.

Agriculture Chemicals and GroundWater Protection Report

The Colorado Water Resources Research Institute. Summarizes the first 15 years of the Agricultural Chemicals and Groundwater Protection Act and provides an overview of activities and monitoring data. View Report.

Agricultural Chemicals and GroundWater Protection Program Water Quality Database System

The database represents all groundwater quality data collected by this program since monitoring began in 1992. It provides groundwater quality monitoring results by year and geographic location for pesticides and inorganic compounds including nitrate–nitrogen. Colorado Department of Agriculture Database.

Best Management Practices for Agricultural Pesticide Use to Protect Water Quality

Colorado State University’s Extension addresses Best Management Practices for preventing non-point source contamination of water resources by agricultural pesticides.


Educational Resources for GMO Information

Curious about GMO?

GMOs, or genetically modified organisms, have been developed with genetic engineering. Humans have been making changes to plant and animal DNA for thousands of years. Currently, there are eight GMO crops available in the U.S.

To find out more information on GMOs, head to GMO Answers where you can find information about how GMOs are made, why farmers plant GMOs, how they are regulated, as well as information about their health and safety.
