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 governing pesticide registration, classification, and use, which makes the label the legally binding document for every application.
- Signal word DANGER
- DANGER marks Category I, the most acutely toxic products, and appears with the skull and crossbones and the word POISON when oral LD50 is below 50 mg/kg.
- Restricted-entry interval
- The minimum time after a pesticide application before workers may enter the treated area without protective equipment; the federal minimum is 4 hours unless the label specifies longer.
- Economic threshold
- The pest population density at which control is justified to keep the population from reaching the economic injury level; it is the basis of integrated pest management treatment decisions.
- Broadcast sprayer calibration formula
- Gallons per acre equals (gallons per minute per nozzle times 5940) divided by (miles per hour times nozzle spacing in inches) for a boom sprayer.
- Withdrawal time
- The label-mandated interval between the last pesticide application and slaughter or milk collection, ensuring residues remain below the tolerance in meat and milk.
- Basal bark treatment
- A forest herbicide technique applying an oil-carrier mixture to the lower 12 to 15 inches of a woody stem, effective on thin-barked species during the dormant season.
- Preemergent crabgrass timing
- Preemergent turf herbicides are applied before weed seed germination; for crabgrass, before soil temperature at 2 inches reaches about 55 degrees Fahrenheit.
- 1/128 acre turf basis
- One one-hundred-twenty-eighth of an acre equals 340 square feet; ounces of spray caught on that area equal gallons per acre.
- Interiorscape spot treatment
- Application to limited areas such as cracks, individual plants, or baseboards inside buildings, using low-odor, low-residue formulations to limit occupant exposure.
- Chemigation backflow protection
- An air gap or check valve that prevents pesticide from siphoning into a water source; required by label and state rules when injecting into irrigation systems.
- Treated seed
- Seed coated with fungicide, insecticide, or nematicide; it must be dyed, labeled, and never used for food, feed, or oil.
- Planter dust
- Abrasive dust from treated seed released by pneumatic planters; managed with fluency agents, deflector shields, and avoiding planting near bloom or in wind.
- Dissolved oxygen crash
- Oxygen depletion after aquatic plants are killed, caused by decomposition; avoided by treating one-third or less of the water body per operation.
- Aquatic-labeled adjuvant
- Only adjuvants registered for aquatic use may be added to herbicides applied to water; other surfactants can be toxic to fish and invertebrates.
- Bare-ground ROW treatment
- Application of residual soil herbicides along rights-of-way to keep vegetation off the surface for a season, using directed spray to protect off-target plants.
- Crack and crevice
- A labeled application method placing small amounts of pesticide into narrow voids inaccessible to people, widely used for cockroaches and ants.
- Bait aversion
- Learned avoidance of a bait formulation by a pest population after sublethal exposure; managed by rotating bait matrices and active ingredients.
- Termiticide trenching
- Applying diluted termiticide into a trench beside the foundation, typically 4 gallons per 10 linear feet per foot of depth according to the label.
- Fumigation Management Plan
- A written document describing fumigation site, sealing, dosage, monitoring, safety, and reentry procedures, required before a structural fumigation begins.
- Clearance testing
- Post-fumigation air monitoring that must show fumigant concentrations below the label reentry level before occupants are allowed back into the structure.
- ULV adulticiding
- Ultra-low-volume application of fine droplets, roughly 10 to 30 microns, for mosquito control, usually in the evening to reduce pollinator exposure.
- Larviciding
- Treating standing water with products such as Bti or methoprene to kill mosquito larvae before they become adults, targeting known breeding sites.
- Section 18 exemption
- An EPA emergency exemption allowing a state to use an unregistered pesticide, or a registered product against a new pest, for a limited period.
- Untreated check plot
- A research plot that receives no pesticide treatment, used to measure pest pressure and to compare efficacy and phytotoxicity of the test treatments.
- M-44 device
- A spring-loaded cyanide ejector set on a stake for coyote control; restricted-use, requiring warning signs and certified applicator supervision.
- Livestock protection collar
- A collar holding a small reservoir of compound 1080 worn by sheep or goats; registered only in certain states and requires carcass recovery.
- Wood retention
- The amount of preservative retained in treated wood, expressed as pounds per cubic foot and compared against AWPA use-category standards.
- Contact time
- The label-specified period a disinfectant must remain wet on a surface to achieve its claimed kill, often ten minutes for hospital-level claims.
- Sewer root foam
- Metam sodium or dichlobenil applied as a foam through cleanouts to kill roots inside sewer laterals, using the label volume per foot of pipe.
- Cooling tower biocide
- An EPA-registered antimicrobial added to tower water to control Legionella and biofilm; oxidizing and non-oxidizing types are alternated to limit resistance.
- Specialty category use
- A pesticide application that does not fit another licensing category; the product label must list the site, and site-specific permits may apply.
