MS Pesticide Applicator flashcards

34 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 U.S. law governing pesticide registration, labeling, and use, administered by the EPA.

Restricted-use pesticide

A pesticide that may be sold only to certified applicators or persons under their direct supervision because of its potential to harm humans or the environment.

Mississippi certifying agency

The Mississippi Department of Agriculture and Commerce (MDAC) administers pesticide applicator certification and licensing in Mississippi.

RUP record retention

Certified applicators must keep records of restricted-use pesticide applications for at least 2 years, including date, location, product, EPA registration number, amount, and applicator.

EPA registration number

A number assigned by EPA to a registered pesticide product, formatted as EPA Reg. No. company number-product number; it identifies the product but does not certify safety.

Worker Protection Standard

Federal regulation requiring agricultural employers to provide a 30-minute decontamination supply, worker notification, and restricted-entry intervals for pesticide applications.

Signal word DANGER-POISON

Label signal word for Category I oral toxicity products with oral LD50 of 50 mg/kg or less, indicating the highest acute toxicity hazard.

Signal word WARNING

Label signal word for Category II toxicity products, indicating moderate acute toxicity hazard to humans.

Signal word CAUTION

Label signal word for Category III or IV products, indicating slight or low acute toxicity hazard.

Restricted-entry interval

The minimum time after a pesticide application before workers may enter the treated area without PPE, as stated on the label.

PPE label minimum

Personal protective equipment listed on the label is the minimum required; applicators may wear more protective equipment but not less.

Directions for use

Label section specifying target pests, application rates, timing, and methods; these directions must be followed exactly.

Precautionary statements

Label statements describing hazards to humans and domestic animals, environmental hazards, and physical or chemical hazards.

Label front panel

The part of the label displaying the product name, signal word, and precautionary statements; directions for use appear on the label body.

Integrated Pest Management

A pest control approach combining cultural, mechanical, biological, and chemical methods, using pesticides only when monitoring shows the economic threshold has been reached.

Economic threshold

The pest population density at which control measures should be initiated to prevent economic loss.

Economic injury level

The lowest pest population density that causes economic loss; it is the basis for setting the economic threshold.

Pest identification

Determining the exact pest species before selecting a pesticide; misidentification can lead to ineffective or illegal applications.

Resistance management

Rotating among pesticide modes of action and using non-chemical controls to delay the development of pesticide resistance in pest populations.

Biological control

Using natural enemies such as predators, parasitoids, and pathogens to suppress pests, while conserving beneficial organisms.

Weed life cycle

Classification of weeds as annual, biennial, or perennial; this guides herbicide selection and application timing.

Pest monitoring

Using scouting, trapping, and degree-day models to track pest populations and inform threshold-based control decisions.

Calibration

The process of measuring and adjusting application equipment to deliver the intended pesticide rate; it must be done before use and rechecked when conditions change.

Broadcast GPA formula

GPA = (GPM × 5940) / (MPH × nozzle spacing in inches), used to calculate gallons per acre for a broadcast boom sprayer.

Measured-area GPA formula

GPA = (ounces collected × 128) / (acres covered), used when calibrating by measuring spray output over a known area.

Nozzle replacement

Replace spray nozzles when their flow exceeds the rated output by more than 10%, because worn nozzles cause uneven application and drift.

Drift reduction

Using low-drift nozzles, lower pressure, higher carrier volume, and applying when wind is 2–10 mph to reduce off-target pesticide movement.

Granular applicator calibration

Measuring granular output over a known distance and checking for uniform flow and proper metering to achieve the intended rate.

Handheld sprayer calibration

Measuring output over a known area and adjusting concentration or walking speed to achieve the intended application rate.

Off-target drift

Movement of pesticide away from the target area that can injure non-target plants, animals, and humans; applicators are responsible for preventing it.

Water resource protection

Applying pesticides at least the label-specified setback from wells, streams, ponds, and drainage, and avoiding application before rain that could cause runoff.

Pollinator protection

Avoiding insecticide applications during bloom, following label pollinator warnings, and applying in the evening when bees are not foraging.

Container triple-rinse

Rinsing pesticide containers three times, then puncturing or crushing them and disposing according to label and state rules.

Spill response

Containing a pesticide spill, protecting water sources, absorbing the material, and reporting the spill as required by law.
