Mixed Deck — All NYS PCO Topics Flashcards

What is the purpose of an anti-drip device (check valve) on a sprayer nozzle?

Answer: To stop liquid flow when pressure drops below the operating threshold, preventing drips

Anti-drip check valves close when operating pressure falls, preventing uncontrolled chemical dripping between spray passes.

What typically happens if a candidate on a PCO eligible list declines multiple job offers or fails to respond to canvass letters?

Answer: The candidate may be marked inactive or removed from consideration for that list or location

Repeated declinations or non-responses can result in a candidate being made inactive or removed from consideration.

Monitoring in IPM serves which primary purpose?

Answer: To identify pest species, population size, and distribution before choosing control tactics

Regular monitoring through trapping, inspection, and sampling provides the data needed to identify pests accurately and make informed control decisions.

NYS requires recertification credits (continuing education) for certified applicators on a cycle of every:

Answer: 3 years

NYS DEC requires certified commercial applicators to complete the required recertification credits during each 3-year certification period.

Dermal absorption is a concern with pesticides primarily because:

Answer: Skin can absorb certain pesticides directly into the bloodstream

Many pesticides, especially organophosphates and carbamates, can penetrate intact skin and enter the bloodstream, causing systemic toxicity.

What is the purpose of calibrating a pesticide application equipment before use?

Answer: To ensure the correct amount of pesticide is delivered per unit area

Calibration ensures that the equipment delivers the label-required rate, preventing under-treatment (poor control) or over-treatment (illegal and potentially hazardous).

When applying a pesticide in a crack and crevice treatment, where should the nozzle be directed?

Answer: Into cracks, crevices, and voids where pests hide

Crack and crevice treatments target the harborage areas where pests live and breed, maximizing efficacy while minimizing human exposure.

Exclusion, as an IPM strategy, involves:

Answer: Sealing entry points to prevent pest access to a structure

Exclusion uses physical barriers — caulking, door sweeps, screens, mesh — to prevent pests from entering a structure.

A technician wants to spray a perimeter treatment but rain is forecast within the hour. What is the BEST decision?

Answer: Postpone the application to avoid runoff and reduced effectiveness

Rain shortly after application can wash pesticide into non-target areas and waterways while destroying efficacy.

PCO appointments are often made to 'trainee' titles. What usually happens upon successful completion of the traineeship?

Answer: The employee advances to the full journey-level title and salary grade

Trainees who complete the traineeship satisfactorily advance to the target journey-level title without re-examination.

What is the minimum education requirement to take the NYS Professional Career Opportunities (PCO) exam?

Answer: A bachelor's degree (or one expected within 12 months of the exam date)

The PCO exam requires a bachelor's degree, or candidates may apply if they expect to earn one within 12 months of the test date.

In New York State, which document must a PCO consult before making any pesticide application?

Answer: The pesticide label, which is a legally binding document

Under FIFRA and NYS law, the pesticide label is a legal document and applicators are required to follow all label directions.

European paper wasps are frequently manageable by destroying or removing a nest (true or false).

Answer: TRUE

European paper wasps, like many social wasps, are highly dependent on their nest for reproduction and colony survival. Removing or destroying their nests, especially early in the season when colonies are smaller, is a very effective method for managing their populations and preventing further activity in an area. This directly eliminates the source of the wasp population.

What does the signal word 'DANGER' on a pesticide label indicate?

Answer: Highly toxic — LD50 is very low

'DANGER' indicates a highly toxic product with a very low LD50, meaning even small amounts can cause death or serious injury.

An IPM inspection report for a commercial kitchen should document all of the following EXCEPT:

Answer: The PCO's personal opinions about the kitchen staff

IPM inspection reports document objective findings — pest ID, harborage locations, conducive conditions, and recommendations — not subjective personnel assessments.

A report shows unit A completed 320 inspections, unit B completed 25% more than unit A, and unit C completed half as many as unit B. How many inspections did unit C complete?

Answer: 200

Unit B completed 400 inspections (320 × 1.25), so unit C completed 200 (400 ÷ 2).

Under New York State law, which agency is primarily responsible for regulating pesticide use and certifying commercial applicators?

Answer: Department of Environmental Conservation (DEC)

The NYS DEC administers pesticide applicator certification and enforcement under Environmental Conservation Law Article 33.

The communication strategy that is most likely to ensure that you comprehend what the other person is seeking to express when you are engaged in conversation with another person is to:

Answer: Repeat back to the person what you believe they are saying

Repeating back or paraphrasing what you believe the other person is saying is a highly effective active listening technique. This allows the speaker to confirm your understanding or correct any misunderstandings, ensuring accurate comprehension and reducing miscommunication. It demonstrates engagement and validates the speaker's message, fostering better communication.

Which of the following best describes an IPM 'preventive' control measure for rodents?

Answer: Sealing gaps larger than ¼ inch with rodent-proof materials before infestation occurs

Preventive exclusion — sealing entry gaps to ¼ inch or less — is the most durable rodent IPM tactic and stops infestations before they start.

A pesticide spill occurs on a customer's driveway. Which sequence reflects the correct 'Three C's' of spill response?

Answer: Control the spill, contain the spread, then clean up the material

The standard response is control the source, contain the spill with absorbent barriers, and then clean up properly.
