32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- FIFRA
- The Federal Insecticide, Fungicide, and Rodenticide Act, the federal law under which EPA registers pesticides and regulates their labeling, sale, distribution, and use.
- Restricted-use pesticide
- A pesticide classification based on risk to people or the environment; it may be applied only by a certified applicator or by someone under a certified applicator's direct supervision.
- Idaho State Department of Agriculture
- The state agency that administers the Idaho pesticide law, issues applicator and dealer licenses, and enforces pesticide regulations within the state.
- Private applicator
- A certified applicator who uses or supervises the use of restricted-use pesticides on land they own or rent to produce an agricultural commodity.
- Commercial applicator
- A certified applicator who applies restricted-use pesticides for compensation or on property owned by another person as part of employment, and who must be licensed.
- Tolerance
- The maximum pesticide residue concentration legally permitted on or in a food or feed commodity, established by EPA and enforced by FDA in interstate commerce.
- Worker Protection Standard
- A federal regulation requiring agricultural employers to provide pesticide safety training, required PPE, decontamination supplies, and restricted-entry intervals for workers and handlers.
- Integrated pest management
- A decision framework combining pest identification, monitoring, thresholds, and multiple control tactics to suppress pests with the least harm to people and the environment.
- Economic threshold
- The pest population density at which control action should be taken to prevent an increasing population from reaching the economic injury level.
- Disease triangle
- A plant disease develops only when a susceptible host, a virulent pathogen, and favorable environmental conditions occur together; removing any one factor prevents disease.
- Piercing-sucking insect damage
- Symptoms such as stippling, yellowing, leaf curling, and honeydew caused by insects that insert mouthparts into plant tissue and remove sap.
- Mode-of-action rotation
- Alternating pesticide products from different mode-of-action groups so that resistant individuals surviving one treatment are controlled by the next product applied.
- Degree-day model
- A prediction tool that accumulates heat units above a pest's developmental threshold to forecast insect life stages and time scouting or treatment.
- Signal word
- A word on the label indicating acute toxicity: DANGER for Category I, WARNING for Category II, and CAUTION for Categories III and IV.
- EPA registration number
- The unique number assigned when EPA registers a pesticide product; it identifies the product on the label and in records and is not the establishment number.
- Preharvest interval
- The minimum number of days allowed between the last pesticide application and harvest of the crop, as stated on the product label.
- Emulsifiable concentrate
- A liquid formulation of active ingredient, emulsifier, and organic solvent that mixes with water to form an emulsion and can injure sensitive foliage.
- Wettable powder
- A dry formulation of active ingredient and inert carriers that is mixed with water and sprayed as a suspension, requiring constant agitation and leaving visible residue.
- Adjuvant
- A material added to a spray mixture to modify its properties, such as a surfactant that reduces surface tension or a sticker that improves rainfastness.
- Restricted-entry interval
- The period after a pesticide application during which entry into the treated area is prohibited without the label-required PPE, as stated on the label.
- LD50
- The dose of a toxicant that kills 50 percent of test animals; a lower value indicates greater acute toxicity and a more restrictive signal word.
- Cholinesterase inhibition
- The action of organophosphate and carbamate insecticides that overstimulates nerve impulses, producing sweating, salivation, tearing, pinpoint pupils, and vomiting.
- Respirator cartridge change
- Cartridges must be replaced according to label directions or whenever breathing resistance increases, or taste, odor, or irritation breaks through the mask.
- Triple rinsing
- Filling a pesticide container one-quarter full with water, rinsing, and pouring the rinse into the spray tank, repeated three times before disposal.
- Poison Control number
- 1-800-222-1222 is the national telephone number for poison emergencies in the United States, staffed 24 hours a day.
- Sprayer calibration
- The process of measuring output, ground speed, and swath width to set and verify the application rate, repeated after nozzle or product changes.
- Nozzle wear
- Worn nozzles pass more flow and produce coarser, uneven patterns; replace nozzles when output exceeds the new-nozzle rating by 10 percent.
- Spray drift
- Off-target movement of pesticide droplets or particles during application, influenced by droplet size, wind speed, boom height, and spray pressure.
- Temperature inversion
- A stable layer of cool air beneath warmer air that traps fine droplets and can carry pesticides long distances; spraying is avoided during inversions.
- Leaching
- Downward movement of a pesticide through soil with water, most likely in sandy, low-organic-matter soils with heavy rainfall, irrigation, or shallow groundwater.
- Backflow prevention
- Keeping the fill hose above the water level or using an air gap or check valve so that tank contents cannot siphon back into a well or water supply.
- Acre
- An area equal to 43,560 square feet, roughly a square field about 208 feet on each side, used to express pesticide application rates.
