Certificate Classifications

Pesticide application certification is divided into classes.

Each class is for a specific type of application as well as what the pesticides is used to control. Details are in each of the boxes below. The boxes link to our homestudy courses page.
All training starts with a core, then has specific lessons for each class. Homestudy training materials are grouped by these classes. Or. if you are adding a classification, you just purchase the particular lessons.

  1. You must be a certified structural pesticide applicator for 2 years before you can take the fumigation classification.
  2. The stored agricultural product fumigation classification is a subset of the fumigation classification. The structural certification isn’t required. However, fumigation is limited to agricultural product pests in grain bins, elevators, rail cars and trucks
  3. Special: Soil Fumigation only authorizes the use of fumigant vapours (eg. chloropicrin) into agricultural soils. Applicants must hold an Agriculture certificate that was issued a minimum of 2 years prior to applying for this certificate.
  4. The industrial classification includes herbicide applications to parking lots and landscaped areas surrounding industrial facilities to control designated noxious and restricted weeds.
  5. The landscape class includes herbicide application to parking lots and roads for control of designated noxious or restricted weeds within urban areas, but doesn’t include brush control.
