Which pesticide schedules can Authorized Assistants apply?

• A. Schedules 1–4 pesticides.
• B. Only Schedule 5 pesticides.
• C. All available pesticide schedules without restriction.
• D. No pesticides can be applied by Authorized Assistants.

Answer: (A)

The key idea is that Authorized Assistants have permission to apply lower-risk pesticides, but not the higher-risk ones. In Alberta, pesticide schedules separate products by risk and the level of training or certification needed to use them. Authorized Assistants can apply products in schedules 1 through 4 because these are considered suitable for use by trained staff under supervision. Schedule 5 products are higher risk and require a licensed pesticide applicator with more specialized training, so an Authorized Assistant does not have authority to apply them. This setup ensures safety for workers, bystanders, and the environment.
