32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- FIFRA
- Federal Insecticide, Fungicide, and Rodenticide Act; the federal law giving EPA authority to register pesticides and set labeling and use requirements.
- EPA registration number
- The number assigned to a registered pesticide product; it must appear on the label and identifies the product and registrant for legal sale and use.
- Restricted-use pesticide
- A pesticide that may be applied only by or under the direct supervision of a certified applicator because of its toxicity or environmental hazard, as designated by EPA or the state.
- Section 24(c) registration
- A special local needs registration allowing a state to add a use to a federally registered product for a local pest problem, with EPA review.
- Maine Board of Pesticides Control
- The state agency that administers Maine pesticide law under 22 M.R.S. Chapter 258, including applicator certification and complaint investigation.
- LD50
- The single dose of a substance that kills 50% of a test population, usually expressed in milligrams per kilogram of body weight; lower values mean greater acute toxicity.
- Signal word DANGER
- The label signal word for Category I acute toxicity products; when oral LD50 is 50 mg/kg or less, the label also bears POISON and the skull and crossbones.
- Restricted-entry interval
- The minimum time after a pesticide application before workers may enter the treated area without required protective equipment; stated on the label and in the Worker Protection Standard.
- Statement of practical treatment
- The first aid information on the label telling what to do after exposure, including whether to induce vomiting and whom to call.
- Chemical-resistant PPE
- Protective equipment made of materials that resist penetration by the specific pesticide formulation and its solvents for the duration of the task.
- Cholinesterase inhibition
- The mechanism of organophosphate and carbamate insecticides; poisoning causes salivation, sweating, pinpoint pupils, and slow heart rate.
- Integrated pest management
- A decision framework that identifies pests, monitors populations, sets action thresholds, and combines cultural, mechanical, biological, and chemical controls.
- Economic threshold
- The pest population density at which the cost of control equals the value of crop loss that would otherwise occur; treatment is justified only above this level.
- Mode-of-action rotation
- Alternating pesticides from different IRAC, FRAC, or HRAC groups to slow the development of resistance in pest populations.
- Degree-day model
- A method using accumulated heat units above a pest-specific base temperature to predict insect development and the timing of susceptible life stages.
- Biological control
- Managing pests with natural enemies such as predators, parasitoids, and pathogens; most effective when broad-spectrum pesticide use is minimized.
- Preemergence herbicide
- A herbicide applied before weeds emerge, forming a soil barrier that controls germinating seedlings; timing and soil moisture affect performance.
- GPA formula
- Gallons per acre equals (gallons per minute times 495) divided by (miles per hour times swath width in inches) for broadcast sprayers.
- 1/128-acre calibration
- A calibration method in which the ounces of spray collected from one nozzle over a measured course equal the application rate in gallons per acre.
- Nozzle wear limit
- Replace a nozzle when its output exceeds 10% above the new-nozzle rate; check all nozzles and replace worn ones as a matched set.
- Pressure and flow
- Nozzle output varies with the square root of pressure; doubling pressure increases flow by about 41%, so pressure is used for fine adjustment only.
- Tank mix order
- The sequence for adding products to a tank, typically water, compatibility agents, dry formulations, liquid formulations, then surfactants, with jar tests for unknowns.
- Triple rinse
- A container-cleaning procedure that rinses a pesticide container three times and adds the rinsate to the spray tank or applies it to a labeled site.
- Spray drift
- Off-target movement of pesticide droplets or particles during application, reduced by nozzle choice, pressure, boom height, wind limits, and avoiding inversions.
- Point-source contamination
- Pesticide release from a concentrated location such as a mixing or loading site or equipment-cleaning area, often preventable with an impervious pad.
- Buffer zone
- A required distance between an application area and a sensitive site such as water, a wetland, a school, or a dwelling, specified by the label or state rule.
- Leaching risk factors
- Sandy soils, high water solubility, low soil organic matter, and high rainfall increase the chance a pesticide moves downward into groundwater.
- Temperature inversion
- A weather condition in which warmer air lies above cooler air near the ground, trapping spray droplets and allowing drift over long distances.
- Spill response sequence
- Stop the source, contain the material with absorbent, protect drains and water, then notify authorities and follow the label's spill instructions.
- Application record
- Documentation of a pesticide application, including date, site, product, rate, and applicator, required by state rule and label and used for traceability.
- Pollinator protection
- Practices that reduce bee and beneficial insect exposure, including avoiding applications to blooming crops and weeds and following label pollinator statements.
- Scouting
- Systematic sampling of representative areas to count pests and compare populations against action thresholds before deciding whether to treat.
