NYS PCO/PCT cheat sheet

A pesticide may be sold, offered for sale, or used in New York only if it is registered with NYSDEC; federal EPA registration alone does not authorize NY sale or use.

General-use pesticides may be applied by the public; restricted-use pesticides (RUP) require certification or application by/under the direct supervision of a certified applicator.

NYSDEC issues commercial, private, and purchase/use permits; private applicators certify to use or supervise RUPs on land they own or rent for agricultural production.

Certification categories in NY include 3A (ornamentals/turf), 3B (turf), 5 (aquatics), 6A (rights-of-way), 7A (structural/general), 7F (food processing), and 10 (research).

Certification is valid for a set term (commonly three years in NY); recertification requires continuing education credits or reexamination before expiration.

A certified applicator must supervise noncertified applicators: direct supervision means the certified applicator is physically present for private applicators; commercial standards differ.

Special local needs (SLN) and emergency exemptions (Section 18) allow limited NY use; the label plus the NY registration/approval governs use.

Dealers must keep records of RUP sales and may sell RUPs only to certified applicators or permitted persons; records are subject to NYSDEC inspection.

Applying a pesticide in a manner inconsistent with its labeling is prohibited under both FIFRA and NY law, even if the use is otherwise agronomically sound.

Signal words rank acute toxicity: DANGER-POISON (Category I, oral LD50 ≤50 mg/kg), DANGER (Category I other routes), WARNING (Category II), CAUTION (Category III/IV).

PPE on the label is the minimum legal requirement; chemical-resistant categories (A–H) must match the solvent - nitrile, butyl, and laminate gloves resist different chemicals.

Never wear leather or cloth gloves for handling concentrates; they absorb and hold pesticide against the skin.

Respirator cartridges must match the hazard (e.g., organic vapor, particulate, or combination) and be replaced per the manufacturer's change schedule.

First aid: move the person to fresh air, remove contaminated clothing, wash skin with soap and water; for eye exposure flush 15 minutes; call poison control (1-800-222-1222) and bring the label.

Spills: protect people, stop the source, contain with absorbent, do not hose into drains; use a spill kit and decontaminate the area.

Triple-rinse or pressure-rinse empty containers, puncture them, and dispose per NYSDEC rules; never reuse pesticide containers.

Heat stress and pesticide exposure can mimic each other; symptoms include headache, nausea, sweating, blurred vision, and weakness - stop work and get medical help.

Transport pesticides in the original labeled container, secured, away from food and passengers, with spill materials on hand.

Integrated Pest Management (IPM) sequence: identify the pest, monitor/threshold, prevent, then use biological, cultural, mechanical, and chemical controls in that order of preference.

Correct identification determines the control: for example, broadleaf weeds need different herbicides than grasses, and mites (8 legs) are not insects (6 legs).

Economic/action threshold is the pest density at which control cost equals expected loss; treat only when monitoring exceeds it.

Resistance management: rotate herbicide modes of action (WSSA groups) and insecticide IRAC groups; do not repeat the same group sequentially.

Selective herbicides (e.g., 2,4-D for broadleaf) spare grasses; nonselective products (glyphosate, glufosinate) injure most plants on contact.

Pre-emergent herbicides act on germinating seeds; post-emergent products act on emerged plants - timing must match the pest's life stage.

Biological controls include predators, parasitoids, and Bt (Bacillus thuringiensis); they require correct timing and reduced broad-spectrum sprays.

Cultural controls include sanitation, crop rotation, resistant varieties, and proper irrigation; these reduce pest pressure without chemicals.

Pesticide fate is driven by solubility, soil adsorption (Koc), volatility, and persistence (half-life); high solubility plus low adsorption increases leaching risk.

Runoff carries pesticides to surface water; leaching moves them into groundwater - both are regulated under NYSDEC and federal water protections.

Buffer zones and setbacks near wells, streams, and wetlands are label requirements; never apply when rain is forecast within the label's restriction period.

Drift is reduced by low-pressure, coarse-droplet nozzles, drift-reduction adjuvants, and applying when wind is low and directed away from sensitive areas.

Sprayer calibration formula: GPA = (GPM × 5940) / (MPH × swath width in inches) - verify before each use.

Temperature inversions (calm, clear evenings) trap fine droplets and cause long-distance drift; avoid spraying during inversions.

Protect pollinators: avoid applying to blooming crops or weeds when bees are foraging, and follow label pollinator-protection statements.

Endangered species and sensitive habitats require label restrictions; check the label and any county bulletins before application.

Dispose of rinse water on labeled sites at labeled rates; never dump into storm drains, ditches, or surface water.

FIFRA (federal) governs pesticide registration and labeling; NY's Environmental Conservation Law (ECL) Article 33 and 6 NYCRR Part 325 add state requirements.

Commercial applicators must keep records of each application (date, location, product, EPA reg. number, rate, area, applicator) and retain them per NYSDEC rules (commonly two years).

Records must be available to NYSDEC on request; falsifying records or applying without certification is a violation subject to penalties.

Report pesticide spills and significant incidents to NYSDEC; certain spills also require reporting to the National Response Center.

Certified applicators must carry certification or proof when applying and display it on request; commercial businesses must be registered with NYSDEC.

Worker protection (WPS) requires notification, re-entry intervals (REI), and PPE for agricultural workers and handlers.

The label is a legal document: directions, restrictions, and precautionary statements are enforceable; off-label use is illegal.

NYSDEC may suspend or revoke certification for violations; penalties can include fines and criminal charges for knowing violations.

Keep records of continuing education credits and renew certification before the expiration date to avoid lapse.
