Colorado Vertebrate Pest Control Practice Test 2026 – Complete Exam Prep

Delivery of a pesticide to where pests can encounter it is called application. This includes putting the pesticide on a plant (spraying, dusting, or other foliar or soil treatments) or releasing it into air or water for pest control. Absorption refers to how the pesticide enters the plant or pest after exposure, not the act of applying it. An adjuvant is a supplementary substance added to improve performance, not the act of delivering the pesticide. An avicide is a pesticide designed to kill birds. So the term that describes the act of placing a pesticide on a plant or releasing it into air or water to control pests is application.
