Ontario Pesticide Core Exam case studies
Ontario Pesticide Core Exam · Put your knowledge to work in context.
The Ontario Pesticide Core Exam is the general-knowledge written test that must be passed, together with a category-specific exam, before Ontario issues a pesticide applicator or operator licence under the Pesticides Act and O. It is written for people who handle or supervise pesticide use as part of their work: farmers and custom applicators, landscape and turf managers, forestry and industrial vegetation crews, structural pest control operators, fumigators, and mosquito or vegetation-control programs run by municipalities and conservation authorities. Because the Core material is common to every category, the exam concentrates on what all applicators must know rather than on any single crop or setting: provincial and federal pesticide law and the duties that come with certification; pest identification, biology and integrated pest management; toxicity, exposure routes, poisoning recognition and personal protective equipment; formulations, modes of action and resistance management; labels and safety data sheets; environmental fate and protection of water, soil, air and non-target organisms; application equipment and calibration; emergency response and spills; and storage, transport and disposal. Prepare by working through the current Ontario Core study manual, reading real product labels rather than summaries, and testing yourself on label interpretation, calculations and PPE decisions. The Ontario Pesticide Core Exam case studies are 5 cases and about 4,055 words.
