VIRGINIA COMMERCIAL PESTICIDE APPLICATORS EXAM
SET 2025 QUESTIONS WITH SOLUTIONS GUARANTEE A+
✔✔- Inspect new seed/plantings for pests before planting
- choose the correct environment for plants to avoid pest issues
- use clean tools
- eliminate diseased specimen from the landscape
- remove fallen leaves and fruit - ✔✔Give examples of proper sanitation:
✔✔- Diseased plants or debris
- Infested soil
- contaminated equipment
- contaminated water
- insect or mite vectors - ✔✔How does disease enter a landscape?
✔✔Planting different annuals each year to prevent disease. This most effective in
preventing soilborne pathogens and nematodes. - ✔✔What is plant rotation?
✔✔Using equipment or manual methods to control pests. e.g. aeration to help prevent
weeds - ✔✔What is mechanical control?
✔✔1. less labor required
2. quick mode of action on a large scale
3. often the most practical and economical
4. can be used when prevention fails
5. consistent - ✔✔What are the benefits of chemical pest control?
✔✔1. often dangerous/toxic
2. risk to environment
3. few long-term benefits
4. can be expensive
5. risk of pesticide resistance - ✔✔What are the downsides of chemical pest control?
✔✔False. Target site (or plant) has to be on the label, but the pest does not. - ✔✔True
or False: You may not legally use a pesticide if your target pest does not appear on the
label
✔✔The ability of a pest population to resist/survive the effects of a pesticide after
repeated exposures. - ✔✔Define pesticide resistance:
✔✔1. use nonchemical methods when possible
2. rotate or combine pesticide with different modes of action
3. use new or altered pesticides
4. limit the application site
, 5. treat alternate generations of pests - ✔✔What are some methods used to manage
pesticide resistance?
✔✔Products that don't kill pests outright. They disrupt normal growth patterns or
behavior. - ✔✔What are insect growth regulators?
✔✔Protectants and curatives(eradicants)
Protectants are preventative
Curatives are for killing or stopping the spread of a current infestation - ✔✔What are the
two main types of fungicides?
✔✔Pesticides registered to treat water molds and downy mildew - ✔✔What are
oomyceticides?
✔✔Fumigants and nonfumigants: soil fumigants are injected as liquids that will
volatilize. Nonfumigants must enter the pest specimen through the cuticle or body
openings - ✔✔What are 2 types of nematicides?
✔✔Sterilization of soil or growth media - ✔✔What is the purpose of steam treatments?
✔✔- placement
- timing
- mobility in the target plant
- persistence
- control spectrum - ✔✔What factors should you consider when choosing an herbicide
for weeds?
✔✔When weeds are small - ✔✔When is it best to apply postemergent herbicide?
✔✔For winter annuals, apply products in later summer/fall. For summer annuals, apply
products in winter/spring - ✔✔When should you apply preemergent herbicides for
annual control?
✔✔Postemergent herbicide - ✔✔What works best for perennial weeds? Pre or
postemergent herbicide?
✔✔Kill-all. Non-selective herbicides that will kill all or most plants - ✔✔What are total
vegetation control products?
✔✔Injury/damage to a sensitive plant caused by chemical exposure. Symptoms include
death of new tissues, stunted/malformed growth, bronzing, leaf spot/necrosis - ✔✔What
is phytotoxicity?
