FIFRA
The Federal Insecticide, Fungicide, and Rodenticide Act governs pesticide registration, labeling, and use in the United States; using a product inconsistent with its label is a violation.
Restricted-use pesticide
A pesticide that may cause unreasonable adverse effects without additional regulatory controls; it may be applied only by or under the direct supervision of a certified applicator.
Signal word
A word on the label indicating acute toxicity: DANGER for Category I, WARNING for Category II, and CAUTION for Category III or IV products.
DANGER-POISON
Label designation for the most toxic Category I products, accompanied by the skull and crossbones symbol; indicates high acute toxicity by oral, dermal, or inhalation exposure.
Restricted-entry interval
The REI is the minimum time after application before workers may enter a treated area without protective equipment; early entry requires label-specified PPE.
Preharvest interval
The PHI is the minimum number of days between the last pesticide application and harvest of the crop, specified on the label to limit residues.
Label is the law
The pesticide label is a legally binding document; applying a product in a manner inconsistent with its directions or restrictions violates federal law.
Direct supervision
For restricted-use pesticides, a certified applicator must be available to supervise and direct the application, with responsibility for the application's compliance with the label.
PPE label requirement
Personal protective equipment requirements are product-specific and listed on the label; applicators must wear at least the gloves, coveralls, footwear, and respirator specified.
Respirator fit test
A fit test verifies that a tight-fitting respirator seals to the face; medical clearance and fit testing are required before use in pesticide applications.
Spill containment
Spill response protects people first, stops the source if safe, contains the spill with absorbent material, and disposes of waste according to label and state rules.
Leaching risk factors
High soil permeability, low organic matter, high water solubility, and heavy rain after application increase the chance a pesticide moves downward into groundwater.
Runoff risk factors
Slope, compacted soil, impermeable surfaces, and rainfall soon after application increase the chance a pesticide moves over the surface into surface water.
Drift reduction
Lower pressure, larger droplets, drift-reducing nozzles, and applying during low steady wind reduce off-target pesticide movement; avoid inversions and gusty conditions.
Temperature inversion
A layer of cool air trapped under warmer air suppresses vertical mixing; small droplets can travel long distances laterally, so spraying during inversions is avoided.
Application records
State law requires records of applications, commonly including date, location, product name, EPA registration number, rate, and applicator identity, retained for a set period.
EPA registration number
A unique number assigned to each registered pesticide product, identifying the registrant and product; it appears on the label and in application records.
Toxicity categories
EPA groups pesticides into Categories I through IV by acute oral, dermal, inhalation, and eye or skin irritation data; Category I is most toxic.
Calibration formula
Gallons per acre = (nozzle output in ounces per minute × 60) ÷ (speed in mph × swath width in feet) × 5,495; recalibrate after equipment or speed changes.
Nozzle replacement rule
Replace a nozzle when its output exceeds 10 percent of the rated flow or its spray pattern is visibly distorted, to maintain accurate application rates.
Integrated pest management
IPM combines monitoring, thresholds, sanitation, and biological controls; pesticides are applied only when pest populations exceed an established action threshold.
Action threshold
The pest population level at which treatment is justified to prevent unacceptable damage; monitoring data are compared to this level before applying a pesticide.
Resistance management
Rotating pesticide mode-of-action groups and using nonchemical controls slows the development of pest resistance to a given product or chemical family.
Tamper-resistant bait station
A locked or secured station that holds rodenticide bait and restricts access by children, pets, and non-target animals, as required by label directions.
Granular application
Granular formulations are applied to soil, turf, or around plants with spreaders; they reduce drift but require incorporation or watering per the label.
Buffer zone
A specified untreated distance between the application area and sensitive sites such as water, dwellings, or schools, stated on the label for certain products or categories.
Aquatic setback
Aquatic-labeled products require maintaining setbacks and buffer strips from water bodies and applying only to sites specifically listed on the label.
Rights-of-way application
Applications along roads, railways, and utility corridors require products labeled for that site, control of drift onto adjacent property, and attention to public access.
Triple rinsing
Rinsing a pesticide container three times with a small amount of diluent and adding the rinsate to the spray tank removes residue before disposal or recycling.
Volatility and drift
Volatile formulations can vaporize and move off target after application; avoid high temperatures and use less volatile formulations near sensitive crops.
Grazing restriction
A label statement specifying the interval after application before livestock may graze or forage treated areas or be fed treated crops.
Structural pest application
Indoor and structural treatments use crack-and-crevice, bait, or spot applications per the label, avoiding contamination of food, utensils, and occupied surfaces.
