32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- FIFRA
- The federal statute governing pesticide registration, labeling, and use in the United States; it makes the label the legal basis for lawful application.
- Restricted-use pesticide
- A pesticide classified by EPA as available only to certified applicators or persons under their direct supervision because of acute hazard or environmental risk.
- Utah private applicator
- A certified applicator authorized to apply restricted-use pesticides for agricultural commodity production on land owned or rented by the applicator or employer.
- Pesticide business license
- A Utah license required for a commercial operation that applies pesticides for hire, held in addition to individual applicator certification.
- Off-label use
- Applying a pesticide in a manner inconsistent with its registered label, such as an unlisted site or a rate above the labeled maximum, which is unlawful.
- Continuing education units
- Credits earned through approved training that certified applicators use to renew certification before the credential expires.
- Signal word DANGER-POISON
- The highest acute toxicity signal word, paired with a skull and crossbones, indicating the most hazardous labeled category for human exposure.
- Restricted-entry interval
- The label-specified time after application during which workers may not enter the treated area without required protective equipment.
- Personal protective equipment
- The gloves, coveralls, eyewear, footwear, and respirator the label requires; label PPE is the minimum acceptable protection.
- Statement of practical treatment
- The label's first-aid directions describing immediate steps after exposure and what information to give a physician.
- Environmental hazards section
- The label section stating groundwater, surface water, wildlife, fish, and bee precautions that constrain where and when the product may be applied.
- Directions for use
- The label section specifying target pest, site, rate, timing, and application method; exceeding the maximum labeled rate is a violation.
- Integrated pest management
- A decision framework combining monitoring, action thresholds, and cultural, biological, mechanical, and chemical tactics to control pests economically.
- Economic threshold
- The pest density at which control measures are justified to prevent the pest population from reaching the economic injury level.
- Mode of action rotation
- Alternating among pesticide MoA groups, classified by IRAC, FRAC, and HRAC, to slow development of resistant pest populations.
- Preemergence herbicide
- A herbicide applied before weed seedlings emerge, typically active on germinating seeds and requiring rainfall or incorporation for activation.
- Postemergence herbicide
- A herbicide applied to weeds after they have emerged, with efficacy depending on weed species, growth stage, and adjuvants.
- Biological control
- Pest management using natural enemies such as predators, parasitoids, and pathogens, often conserved by choosing selective pesticides and timing.
- Pest life cycle stage
- The developmental phase of a pest, such as larva or adult, that determines which stage is most susceptible to a chosen control tactic.
- Sprayer calibration formula
- GPA equals (GPM per nozzle times 5940) divided by (MPH times nozzle spacing in inches); used to set and verify broadcast application rate.
- Nozzle flow formula
- GPM equals (GPA times MPH times nozzle spacing in inches) divided by 5940; used to select the correct nozzle size for a target rate.
- Pressure and flow relationship
- Nozzle output varies with the square root of pressure, so doubling pressure raises flow only about 41 percent, not double.
- Nozzle replacement rule
- Replace worn nozzles when measured output exceeds the new-nozzle flow rate by roughly 10 percent, which otherwise causes over-application.
- Speed and rate relationship
- Application rate is inversely related to ground speed at fixed nozzle output; increasing speed lowers GPA, so maintain consistent speed.
- Boom height and overlap
- Boom height and nozzle spacing set pattern overlap; following manufacturer recommendations prevents streaks, gaps, and double-covered strips.
- Granular applicator calibration
- Catch output over a measured distance, then convert to pounds per acre using swath width and speed to set the correct delivery rate.
- Spray drift
- Off-target movement of pesticide droplets or particles, reduced by coarser droplets, lower boom height, buffers, and favorable wind conditions.
- Rainfast interval
- The label time after application before rainfall will no longer reduce efficacy; applying when rain is imminent risks runoff and failure.
- Pollinator protection
- Following label bee precautions, avoiding applications to blooming crops during foraging, and timing sprays to low-bee-activity periods.
- RUP application record
- A required record listing date, site, product and EPA registration number, rate, total amount, applicator, and target pest.
- Record retention period
- The length of time restricted-use pesticide records must be kept and made available for inspection under Utah and federal rules.
- Container triple rinse
- Rinsing a pesticide container three times, adding rinse water to the spray tank, then disposing of the container per label directions.
