KY Pesticide Applicator cheat sheet

FIFRA is the federal law that requires EPA registration of pesticides and makes the label enforceable; use inconsistent with the label is a violation.

Restricted-use pesticides may be applied only by certified applicators or by persons under their direct supervision as allowed by the label and state rules.

Signal words on labels: Category I highly toxic uses DANGER (with POISON and skull/crossbones when applicable), Category II WARNING, Categories III and IV CAUTION.

The label must be followed for site, pest, rate, method, PPE, reentry interval (REI), preharvest interval (PHI), storage, and disposal.

Certified applicators must keep records of restricted-use pesticide applications for at least two years under FIFRA.

Labeling includes the container label plus supplemental written material; both are enforceable.

The Kentucky Department of Agriculture administers applicator certification and pesticide enforcement in Kentucky.

A product's EPA registration number and establishment number identify the registered product and production site; they are not the same as the lot number.

IPM sequence: prevent pests, monitor with scouting, compare counts to thresholds, intervene only when justified, and evaluate results.

Action threshold is the pest density at which control is warranted; economic injury level is the density at which control cost equals crop loss prevented.

Scout representative areas in a pattern such as W or zigzag, record pest and beneficial counts, and compare with thresholds.

Economic injury level formula: EIL = cost of control ÷ (crop value per unit × injury per pest).

Biological control conserves or releases predators, parasitoids, and pathogens; broad-spectrum insecticides can disrupt it.

Cultural controls include crop rotation, sanitation, resistant varieties, planting-date shifts, and habitat modification.

Mechanical/physical controls include tillage, barriers, traps, hand removal, and temperature or light treatments.

Resistance management: rotate herbicide, insecticide, or fungicide mode-of-action groups and use labeled full rates; sublethal rates accelerate selection.

Disease triangle: disease requires a susceptible host, virulent pathogen, and favorable environment; removing one factor limits disease.

The label PPE statement is the minimum legal requirement; additional PPE may be needed for mixing, loading, or spill response.

Chemical-resistant gloves are nitrile, neoprene, butyl, or similar; leather and cotton absorb pesticides and are not chemical-resistant.

Respirator use requires the correct cartridge for the hazard, a fit check each use, and fit testing; a tight seal needs a clean-shaven face.

Mixing and loading cause the highest applicator exposure; wear labeled gloves, apron, eye/face protection, and footwear.

Dermal exposure is the most common route; remove contaminated clothing and wash skin with soap and water promptly.

Eye contact: flush with clean water for at least 15 minutes and seek medical attention; bring the label.

Heat stress signs include dizziness, nausea, weakness, confusion, and fainting; cooling and medical evaluation are required.

Organophosphate or carbamate poisoning can cause cholinergic signs such as sweating, salivation, vomiting, and pinpoint pupils; seek emergency care.

Contaminated work clothing must be changed promptly and washed separately from family laundry.

Broadcast GPA = (GPM per nozzle × 5940) ÷ (MPH × nozzle spacing in inches).

Nozzle GPM = (GPA × MPH × nozzle spacing in inches) ÷ 5940.

Acres per tank = tank capacity in gallons ÷ spray rate in GPA.

Product per tank = labeled rate per acre × acres per tank.

1/128 acre = 340 square feet; for a boom width W feet, calibration course length = 340 ÷ W feet.

In the 1/128-acre method, ounces collected per nozzle equal GPA because 128 fluid ounces = 1 gallon.

Nozzle flow varies with square root of pressure: to double flow, increase pressure fourfold; to raise flow 10%, raise pressure about 21%.

For fixed nozzles, increasing ground speed lowers GPA proportionally; doubling speed halves GPA.

Drift risk increases with smaller droplets, higher boom height, higher speed, wind, and temperature inversions.

Store pesticides in a locked, ventilated area away from food, feed, seed, animals, and water wells; keep products in original labeled containers.

Never leave a spray tank filling unattended; use an air gap or backflow prevention device to prevent back-siphoning into water supplies.

Transport pesticides in a secured cargo area separated from passengers and food; carry a spill kit, PPE, and labels.

Spill response: protect people, stop the source if safe, contain with absorbent, avoid runoff to water, and dispose per label and state rules.

Triple rinse: drain container, add rinse water, rotate, drain into spray tank; repeat three times, then puncture or recycle as allowed.

Pressure rinsing with a special nozzle is an acceptable alternative to triple rinsing when the label allows it.

Leaching risk is higher for pesticides with high water solubility, high persistence, and low soil adsorption, especially in sandy soils.

Buffer zones and endangered-species restrictions on the label limit applications near water, homes, schools, and habitat.

Do not burn pesticide containers unless the label specifically permits it; follow label and state container-disposal rules.
