32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Minnesota pesticide certification agency
- The Minnesota Department of Agriculture issues pesticide applicator certifications and enforces pesticide law, including record inspections and misuse investigations.
- Restricted-use pesticide definition
- A pesticide classified by EPA as restricted because of acute toxicity or environmental hazard; it may be applied only by or under the direct supervision of a certified applicator.
- Record retention period
- Minnesota requires restricted-use pesticide application records to be kept for at least three years from the application date and made available to MDA on request.
- Label as legal document
- The EPA-approved label is enforceable law; applying a product in a manner inconsistent with its labeling is a violation under federal and Minnesota law.
- Signal word DANGER
- Indicates the highest acute toxicity category (Category I) and may appear with the skull and crossbones symbol and the word POISON on the label.
- Signal word CAUTION
- Indicates lower acute toxicity (Categories III and IV); it does not mean the product is harmless and label PPE still applies.
- Reentry interval REI
- The label-specified time after application before workers may enter the treated area without protective equipment; posting and notification may be required.
- Preharvest interval PHI
- The label-specified number of days between the last application and harvest; harvesting earlier can leave illegal residues and cause crop rejection.
- Sprayer calibration formula
- Gallons per acre equals ounces collected times 128, divided by nozzle spacing in inches times distance traveled in feet.
- Tank mix order
- Add products in the order: water, compatibility agent, dry powders and flowables, liquid flowables, emulsifiable concentrates, surfactants, then water to final volume.
- Temperature inversion risk
- Stable air with little vertical mixing traps fine droplets and moves them long distances; avoid application during inversions, common at dawn and dusk.
- Drift reduction methods
- Lower spray pressure, coarser droplets, lower boom height, correct nozzles, buffer zones, and applying only when wind favors safe conditions reduce off-target movement.
- Pesticide resistance rotation
- Rotate among IRAC, FRAC, and HRAC mode-of-action groups and use full labeled rates to slow resistance; never rely on sublethal doses.
- Dermal exposure route
- Skin contact is the most common exposure route for applicators; intact chemical-resistant gloves and coveralls are the primary defense.
- Cholinesterase inhibitor symptoms
- Organophosphate and carbamate poisoning can cause weakness, sweating, salivation, pinpoint pupils, and breathing difficulty; seek medical care and bring the label.
- Groundwater protection practice
- Mix and load at least 100 feet from wells and surface water, use anti-backflow devices, and avoid application before heavy rain when the label warns of runoff.
- Aerial pilot certification
- Aerial applicators need a Minnesota aerial category certification plus an FAA pilot certificate and Part 137 operating certificate for agricultural aircraft operations.
- Aerial swath width
- The width of the spray pattern deposited by one pass; it depends on nozzle type, boom pressure, release height, and wind, and requires overlap to avoid streaks.
- Aerial calibration formula
- Gallons per acre equals flow rate in gallons per minute times 8.34, divided by acres treated per minute.
- Aerial wind measurement
- Measure wind speed and direction at the application site with a calibrated anemometer, and record the reading with the application record.
- Aerial buffer zone
- A label-specified distance from the treated area to sensitive sites; it may expand with wind speed and must be followed exactly.
- Aerial flagger requirements
- Flaggers mark swath edges when the pilot cannot see them; they must wear high-visibility clothing and be protected from spray exposure.
- Aerial loading site setback
- Load and mix at least 100 feet from wells, streams, and lakes where practical, and use containment to catch spills at the loading site.
- Aerial shutoff system
- A cockpit-controlled positive shutoff stops spray flow immediately; test it before each application to prevent overspray at field ends.
- Aerial application records
- Records must include aircraft ID, pilot, date, time, location, product, EPA registration number, rate, area, and weather, kept at least three years.
- Rights-of-way acre calculation
- Acres treated equals length in feet times width in feet, divided by 43,560; use the treated width, not the whole roadside.
- Aquatic acre-foot calculation
- Acre-feet equals surface acres times average depth in feet; aquatic herbicide rates are based on water volume or surface area, not land area.
- Aquatic permit requirement
- Minnesota aquatic pesticide applications require an MDA permit or NPDES coverage, with public notice and reporting conditions specified in the permit.
- Termiticide linear-foot rate
- Termiticide labels specify application rates per linear foot of trench and per post; measure trench length and depth and do not exceed the annual maximum per structure.
- Fumigation dosage formula
- Dosage equals the label rate per 1,000 cubic feet times the treated volume in cubic feet divided by 1,000; verify sealing and monitor concentration.
- ULV mosquito adulticiding
- Ultra-low-volume application uses label-specified flow rates and droplet sizes; calibrate equipment and avoid application when bees are foraging.
- Structural IPM first step
- Inspect and identify the pest and the conditions supporting it before treating; treat only after locating the infestation and setting an action threshold.
