CSU Pesticide Applicator Training

Our program has developed an online course to prepare you for the general licensing exam. Through our comprehensive training, participants will learn the essential aspects of pest management strategies, pesticide properties, environmental and public safety, applicator safety, and relevant laws and regulations for Colorado applicators.

Private Applicators

​ According to CDA, a Private Applicator is a person who uses or supervises the use of a restricted-use pesticide (RUP) for the purpose of producing an agricultural commodity on property owned or leased by the applicator or the applicator’s employer or, if the pesticide is applied without compensation other than trading of personal services between producers of agricultural commodities, on the property of another person must be a licensed private applicator.

Private applicators do not apply pesticides in exchange for compensation, but only to produce a commodity. If you are hired to apply pesticides in agricultural settings in exchange for payment then you are a commercial applicator, which we will cover later.​

Private Applicator Licensing Process

  1. To be approved for a Private Applicator License, you must first take the general private applicator exam (Category 401). In preparation for this proctored exam, the CDA, in collaboration with our program, has provided a study guide. Additionally, we have developed an online pesticide applicator training that will prepare you for the exam and beyond.
  2. You will also be required to read and understand the Colorado Pesticide Applicator’s Act and the associated Rules and Regulations prior to taking the exam or applying pesticides.
  3. To take the exam, you must register on the Metro Institute online testing website and follow the instructions carefully to complete the exam application and schedule a proctored test.
  4. There is an examination fee of $41.50 per test for this portion of the licensing process.
  5. After you have completed and passed your exam with a 70% or more, you must submit your application for a Private Applicator License (note: the application begins at the bottom of the page). The application fee is $75.
  6. In some cases you will need to take additional exams. For private applicators using any fumigants, you will need to take a fumigation test (e.g., Category 303: Structural Fumigation, Category 309A: Soil Fumigation, or Category 309B: Non-Soil fumigation), and if you are making any pesticide applications with aerial equipment, you will need to take the aerial exam, Category 114. These tests can also be scheduled through your account at the Metro Institute.
