NY Pesticide Applicator cheat sheet

FIFRA requires every pesticide sold or distributed in the U.S. to be EPA-registered; New York also requires state registration by DEC before sale or use in the state.

Label signal words rank acute toxicity: DANGER (Category I), WARNING (Category II), CAUTION (Category III/IV); DANGER plus POISON and a skull-and-crossbones means highly toxic by any route.

New York commercial applicators must keep records of restricted-use pesticide applications for at least three years and make them available to DEC on request.

The label is the legal document; using a pesticide in a manner inconsistent with its labeling violates FIFRA and state law.

PPE must be worn exactly as the label specifies; respirators require fit testing, medical evaluation, and a cartridge change schedule.

Empty containers: pressure or triple rinse, add rinsate to the spray tank, then puncture or crush; open burning is prohibited in New York.

Drift is reduced by low pressure, coarse droplets, drift-reduction nozzles, buffer zones, and avoiding application when wind exceeds label limits or during temperature inversions.

Spill response: stop the source, contain with absorbent or soil, protect drains and surface water, and report spills to DEC as required.

The restricted entry interval is the label-specified time after application before workers may enter without PPE.

Integrated pest management sequences scouting, thresholds, biological and cultural controls, and treats chemical control as the last step.

Economic threshold: treat only when the value of expected crop loss exceeds the cost of treatment plus environmental risk.

Preharvest intervals must be observed; harvesting before the PHI can leave residues above the established tolerance.

Rotate herbicide mode-of-action groups (WSSA/HRAC) and insecticide IRAC groups to delay resistance.

Protect pollinators by not applying to blooming crops, mowing blooming weeds before application, and spraying in late evening when bees are not foraging.

Livestock products require following withdrawal times and label directions for pour-ons, sprays, and feed-through treatments.

Seed treatments and soil-applied herbicides need accurate calibration; over-application injures seedlings.

2,4-D amine is safer near sensitive broadleaf crops than the ester, which can volatilize and move off site.

Site preparation, conifer release, and timber stand improvement are the main forest herbicide uses, commonly with glyphosate, triclopyr, imazapyr, or 2,4-D.

Cut-stump, hack-and-squirt, basal bark, and stem injection are targeted methods that reduce off-target injury compared with broadcast spraying.

Leave streamside management zones and buffers along water; many forest herbicides are restricted near surface water.

Dormant-season and stem-injection applications reduce drift risk when foliage is absent and sensitive species are inactive.

Outbreaks of spongy moth, hemlock woolly adelgid, and emerald ash borer may require aerial or systemic treatments under a NY-approved plan.

Soil persistence and leaching vary by herbicide; picloram and imazapyr persist long enough to affect replanting.

Post-treatment signage and re-entry intervals apply to forest workers as well as to the public.

Calibrate spreaders and sprayers before each season; never exceed the label rate per 1,000 square feet.

Granular products must be watered in unless the label prohibits it; avoid applying to hard surfaces where granules can reach storm drains.

Phytotoxicity risk rises with high temperature, drought stress, tank mixes, and repeated use of the same mode of action.

Systemic insecticides applied as drenches or injections move into foliage and control sap-feeding insects.

Fungicide resistance is managed by rotating FRAC groups and combining them with cultural practices.

New York requires commercial lawn applicators to post signs and give neighbor notification before residential turf applications.

Avoid mowing or irrigating too soon after application if the label specifies a waiting period.

2,4-D and other auxin herbicides can injure ornamentals through drift and volatilization; use amines and low pressure near sensitive plants.

Only products labeled for aquatic use may be applied to water; most applications also require a NY DEC aquatic pesticide permit.

Treat algae in sections because decaying vegetation depletes dissolved oxygen and can kill fish.

Identify the target - algae, submersed, emergent, or floating - before choosing a contact or systemic herbicide.

Subsurface injection and granular formulations reduce drift and place the active ingredient at the target depth.

Applications near potable water intakes are restricted; check setback distances on the label and permit.

Copper products control algae but can accumulate in sediments and harm non-target invertebrates.

Record water temperature, pH, and dissolved oxygen; some herbicides are less effective or more toxic under certain conditions.

Right-of-way programs combine bare-ground residuals, contact herbicides, and mechanical mowing along roads, rails, and utility corridors.

Low-volatile esters or amines reduce vapor drift near sensitive crops; avoid ester formulations when temperatures exceed label limits.

Soil-residual herbicides on industrial sites can leach to groundwater; follow label restrictions for sandy soils and wellhead areas.

Timing windows - dormant stem, early foliar, late foliar, and basal - each target different brush species and seasons.

Drift control near roads and railways uses shielded booms, coarse droplets, and buffer strips.

Picloram and other persistent herbicides can carry over and injure crops when treated vegetation is composted or moved.

Posting and notification requirements apply on rights-of-way adjacent to residential or agricultural land.

Structural IPM begins with inspection, sanitation, and exclusion before any pesticide is applied.

Indoor work uses crack-and-crevice, void, or spot treatments; broadcast baseboard sprays are limited by label directions.

Rodenticides in occupied buildings must be placed in tamper-resistant bait stations and secured.

Termite control uses soil-applied termiticides, baits, or wood treatments; labels specify depth, rate, and distance from foundations.

Space and fumigant treatments require licensed applicators, placarding, and entry restrictions until clearance.

Cockroach and ant baits are placed near harborage and must not be covered by residual sprays.

Read the label for site limitations; many products are labeled for outdoor perimeter use only.

Keep records of structural applications including target pest, product, rate, and location.

Never apply pesticides where food, utensils, or food-contact surfaces are exposed; cover or remove food before treatment.

Food-contact surfaces must be cleaned and sanitized after treatment before food operations resume.

In food plants, rodent control relies on exclusion, sanitation, and tamper-resistant stations placed outside production areas.

Space treatments and fogs are used in food storage only when the label permits and equipment is protected.

Stored-product pests are managed with pheromone monitoring, aeration, and fumigation by a certified applicator.

Health care facilities require coordination with staff for patient protection and posting of treated areas.

HACCP and GMP programs require documentation that pesticide use will not contaminate product.

New York pesticide law is in ECL Article 33 and implemented through 6 NYCRR Parts 325, 326, and 327.

Certification categories include private, commercial, and purchase permits; each has separate examination and fee requirements.

Every trial needs an untreated check and replication to measure treatment effect.

Randomize treatments and use block designs to control field variability.

Record plot size, rate, carrier volume, timing, and environmental conditions for every application.

Residue trials must follow the label and PHI; treated crops from research plots may not enter commerce without authorization.
