Ontario Pesticide Landscape Exam study guide
Ontario Pesticide Landscape Exam · Work through your exam, one topic at a time.
The Ontario Pesticide Landscape Exam is the provincial certification exam for people who apply pesticides to turf, ornamentals, trees, and other landscape sites as part of their work. In Ontario's classification system this is the Landscape class of applicator certificate, and holding it is what allows a technician or business operator to apply, or supervise the application of, landscape pesticides legally. The Ontario Pesticide Landscape Exam study guide has 9 sections and about 3,308 words.
01Pest Identification and Biology
A candidate must be able to place a problem organism into a group (insect, mite, weed, disease pathogen, mollusc, vertebrate) and then into a life stage. Questions test whether you can distinguish chewing damage (notched leaves, frass) from piercing-sucking damage (stippling, honeydew, sooty mould), and whether you recognise that mites are arachnids with eight legs as adults, not insects.
393 words, about 2 min02Integrated Pest Management and Decision-Making
Candidates must be able to state the IPM hierarchy in order: prevention and cultural controls first (resistant cultivars, sanitation, crop rotation, proper irrigation and fertility, physical barriers), then monitoring, then biological and mechanical tactics, then - only when justified - chemical control. Questions test whether you can place a tactic in the correct tier and whether you understand that pesticides are a component of IPM, not its opposite.
370 words, about 2 min03Pesticide Products, Formulations, and Modes of Action
Candidates must match formulation letters to behaviour: EC (emulsifiable concentrate, solvent-based, can damage tender foliage and some plastics), SC or F (suspension concentrate/flowable), WP (wettable powder, requires good agitation, leaves visible residue), WDG or DF (water-dispersible granule), SL (soluble liquid), and formulations such as dusts, granules and baits used for specific sites. Understand that the active ingredient is only part of the product; carriers, surfactants and solvents affect phytotoxicity, rainfastness, mixing order and compatibility.
372 words, about 2 min04Labels, Regulations, and Legal Requirements
In Ontario, pesticide use is governed by the provincial pesticide legislation and its regulation, with federal registration and classification under the federal pest control products law. Candidates must understand that the label is a legal document: the site, pest, rate, timing, application method, personal protective equipment, restricted-entry interval, storage and disposal directions are all binding.
373 words, about 2 min05Human Health, Exposure, and Personal Protective Equipment
Candidates must know the four exposure routes: dermal, inhalation, oral and ocular, with dermal being the most common in landscape work. Understand the difference between acute toxicity (single exposure, expressed through signal words and hazard statements) and chronic toxicity (long-term effects such as carcinogenicity or reproductive harm).
382 words, about 2 min06Environmental Fate, Non-Target Effects, and Pollinator Protection
Candidates must understand the main fate pathways: drift, volatilisation, runoff, leaching, adsorption to soil and organic matter, microbial breakdown, hydrolysis and photodegradation. Learn the factors that increase movement: wind, small droplets, high temperature, low humidity, coarse or cracked soils, shallow water tables, and application just before rain.
347 words, about 2 min07Application Equipment, Calibration, and Application Techniques
Candidates must be able to explain why calibration precedes every application and how to calculate output. Know the relationship: output per area depends on nozzle flow, spray pressure, speed and swath width.
351 words, about 2 min08Storage, Transport, Spill Response, and Disposal
Candidates must know the storage requirements: a secure, locked, ventilated structure not subject to flooding, with pesticides kept off the floor on shelves, away from food, feed, seed, livestock and personal protective equipment, and separated from fertilizers and flammables as directed. Keep products in original labelled containers; never store in beverage containers.
362 words, about 2 min09Record Keeping, Emergency Response, and Professional Conduct
Candidates must know what a pesticide application record must contain: date and time, site and location, pest and target, product name and registration number, rate and total amount applied, application method and equipment, weather conditions (temperature, wind speed and direction), applicator name and licence number, and any relevant notes. Records must be kept for the period required by regulation and made available on request.
