NJ Pesticide Applicator cheat sheet

IPM sequence: identify the pest, monitor and set action thresholds, prevent with cultural/sanitation tactics, then use biological, mechanical, and chemical controls as needed.

Economic threshold = pest density at which control cost equals crop loss avoided; treat at or above threshold, not at first sighting.

Pesticide label is a legal document: the label directions and the labeling (including supplemental and SLN labels) govern legal use.

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

Resistance management: rotate among IRAC/FRAC/HRAC mode-of-action groups; repeated use of one group selects resistant biotypes.

Pesticide types: contact vs. systemic; protectant vs. curative/eradicant; selective vs. nonselective; residual vs. short-lived.

Formulations: EC (emulsifiable concentrate), WP/WDG (wettable powder/dispersible granule), SC (suspension concentrate), flowable, dust, bait, fumigant - each affects mixing, agitation, and phytotoxicity risk.

Pest categories: insects (chewing/sucking), mites, plant pathogens (fungi, bacteria, viruses), nematodes, weeds (grasses, broadleaves, sedges), vertebrates.

Carryover and phytotoxicity depend on soil persistence (half-life), soil type, organic matter, pH, and crop rotation interval stated on the label.

Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) governs registration, labeling, and use of pesticides in the U.S.; EPA administers it.

FIFRA classifies pesticides as general-use or restricted-use (RUP); RUPs may be applied only by or under the direct supervision of a certified applicator.

Certification categories in New Jersey include private applicator and commercial (core plus category) credentials; certification periods and recertification credits are set by the state lead agency (NJDA).

A Special Local Need (SLN, FIFRA Section 24(c)) label permits a state-specific use; a Section 18 emergency exemption permits unregistered use for a declared emergency.

Tolerance (maximum residue limit) is set under the Federal Food, Drug, and Cosmetic Act; residues must not exceed the tolerance on food/feed commodities.

Worker Protection Standard (WPS) covers agricultural workers and pesticide handlers: REI, notification, PPE, decontamination, and training requirements.

Recordkeeping: certified applicators must retain application records as required by federal and state rules; RUPs and WPS have specific retention periods.

Misuse is use inconsistent with the label; applying to a non-labeled site or at an excessive rate is a violation subject to civil and criminal penalties.

Restricted-entry interval (REI) is the period after application during which entry is prohibited without required PPE; it appears on the label.

Exposure routes: dermal (most common), inhalation, oral, and eye contact; dermal absorption varies with formulation and skin condition.

PPE selection follows the label: gloves, coveralls, respirator, eye protection, footwear; chemical-resistant gloves are not the same as waterproof.

Signal words and precautionary statements indicate hazard; first aid statements on the label direct decontamination and medical response.

Symptom recognition: cholinesterase-inhibiting insecticides (organophosphates, carbamates) can cause SLUDGE/muscarinic signs - salivation, lacrimation, urination, diarrhea, GI upset, emesis.

Sensitivity: some people develop pesticide sensitivity; report symptoms and seek medical care; the label and Safety Data Sheet (SDS) provide hazard information.

Environmental fate: drift, runoff, leaching, volatility, and persistence; buffer zones, setback distances, and wind/weather limits reduce off-target movement.

Protect pollinators: avoid applying to blooming crops when bees are foraging; follow label pollinator protection and timing restrictions.

Protect groundwater and surface water: avoid application near wells, sinkholes, and water bodies; follow label setbacks and do not mix/rinse near water.

Spill response: contain, absorb, and dispose per label and regulations; triple-rinse containers and follow state disposal rules.

Calibration formula: GPA = (GPM × 5940) / (MPH × nozzle spacing in inches) for broadcast boom sprayers.

Nozzle flow scales with pressure: flow varies approximately with the square root of pressure (doubling pressure increases flow about 1.41×).

Nozzle selection: flat-fan for broadcast, even-flat-fan for broadcast overlaps, drift-reducing/air-induction for coarse droplets, cone for directed/banded.

Drift management: larger droplets, lower pressure, lower boom height, correct nozzle, and favorable wind reduce drift; avoid inversions and high wind.

Sprayer calibration steps: measure nozzle output, measure speed, calculate GPA, then adjust rate by changing pressure, speed, or nozzle size.

Granular applicators: calibrate by catching granules over a measured distance and weighing; check for uniformity across the swath.

Equipment maintenance: check nozzles for wear (flow >10% above new indicates replacement), clean filters, and verify pressure gauges.

Application techniques: banded, broadcast, directed, soil-incorporated, and fumigation; match method to label directions and pest target.

Tank mixing order (typical): fill with water, add compatibility agents, then wettable powders/dry formulations, then liquids, then surfactants/adjuvants last.
