QAL - Category A Exam Questions With Correct
Answers 100% Verified
List and explain the criteria used to select a pesticide for use in a school. -
ANSWER -Safety - Low acute toxicity (high LD50), no known chronic health
effects, not highly mobile or volatile, not be persistent
Species specificity - specific to the type of pest and not toxic to other
plants/animals
Effectiveness - effective against the target pest without harming non target
organisms
Endurance - must not promote resistance or tolerance among the targeted pest
Speed - suitable for the immediate pest problem. Quick acting in an emergency,
slower action for non-emergency over a more toxic alternative
Cost - must be cost-effective
Handling Pesticides - ANSWER -- Wear PPE
- Do not drop or throw container/packages
- Check for contamination or leaks
- Never leave unattended or store in unlocked areas
- Keep away from food/water, heat sources and fire
- do not eat, drink or smoke
- Wash thoroughly when finished with handling duties and before eating, drinking,
smoking, or using the bathroom
List the steps to take in order to properly apply pesticides - ANSWER -- Calibrate
application equipment
- Use the correct amount of active ingredient
- measure the treatment area
- check the application site for hazards
,- make sure weather conditions are suitable
- prevent drift
- set up an application pattern that prevents you from having to walk or drive
through treated areas
- never apply in or near air conditioning or heating vents/ducts
- Keep people and animals away
- use specialized application equipment or formulated products when possible
Storing Pesticides - ANSWER -- store in original, tightly closed containers
- protect from extreme temperatures and from becoming wet
- Always keep the storage area locked
- Store in well ventilated, well lighted, dry areas.
- Always keep children, animals and unauthorized people away from pesticides.
- NEVER put them in unmarked or food containers.
- NEVER store pesticides with food products, livestock feed or fertilizer.
- Always store PPE in a clean area away from pesticides.
Explain why it is important to keep an up-to-date inventory of stored pesticides -
ANSWER -Expired pesticides are deemed hazardous waste unless someone can
legally use them to control pests
Pesticide Disposal - Containers - ANSWER -Triple rinse then offer for recycling
or reconditioning, or puncture and dispose of in a sanitary landfill (Class 2)
Pesticide Disposal - chemical - ANSWER -- Never dump pesticides or pesticide
mixtures onto the soil or into a sewage system
- Send to an approved Class 1 dumpsite (Haz Waste Facility)
pesticide formulations - ANSWER -Liquids
Wettable Powders (WP)
Emulsifiable Concentrates (EC)
Soluble Powders (SP)
Dry Flowables (DF)
Flowables (F)
Granules (G)
, Dusts (D)
Baits
Capsule Suspension (CS)
Gels
Suspension Concentrates (SC)
Solutions (S)
Liquids - ANSWER -water or oil soluble
Advantages - mix easily, easy to handle
Disadvantages - spillage and splashing are common
Wettable Powders - ANSWER -dry products mixed with water, but are not
entirely soluble so require agitation, most contain 15-75% active ingredient
Uses - insecticides, fungicides, herbicides
Advantages - One of the safest formulations for use on plants for insect or disease
control
Disadvantages - requires agitation, may leave visible residues on treated surfaces,
does not penetrate surfaces well. Abrasive to nozzles and pumps
Emulsifiable Concentrates (EC) - ANSWER -oil-based formulations include
emulsifying agents to help them mix with water
Uses - insecticides, fungicides, herbicides
Advantages - Not abrasive to application equipment
Disadvantages - May deteriorate rubber and plastic seals and hoses, injure plant
foliage, may cause damage to certain types of surfaces, can be easily absorbed
through the skin
