FIFRA

The Federal Insecticide, Fungicide, and Rodenticide Act is the federal law that requires pesticides to be registered by EPA and governs their labeling, sale, distribution, and use in the United States.

Related: EPA registration number, Restricted-use pesticide, Pesticide label and labeling
EPA registration number

A unique number assigned to each registered pesticide product and printed on its label, identifying the manufacturer and product and showing the product is federally registered.

Related: FIFRA, Pesticide label and labeling
Restricted-use pesticide

A pesticide that EPA determines may cause unreasonable harm to people or the environment even when used as directed, and that may be applied only by or under the direct supervision of a certified applicator.

Related: Certified applicator, FIFRA
Certified applicator

A person who has passed the required examinations and been licensed by Florida to apply, or to supervise the application of, restricted-use pesticides within the state.

Related: Restricted-use pesticide, Florida Department of Agriculture and Consumer Services (FDACS)
Florida Department of Agriculture and Consumer Services (FDACS)

The state agency that licenses pesticide applicators, registers pesticide products sold in Florida, and enforces Florida pesticide law, often through its Office of Agricultural Law Enforcement.

Related: Certified applicator, Special local need (24(c)) registration
Special local need (24(c)) registration

A state-issued registration that allows sale and use of a pesticide product for an additional use in Florida when a pest problem is not adequately controlled by federally registered products.

Related: FIFRA, Pesticide tolerance
Pesticide tolerance

The maximum pesticide residue level that EPA allows in or on a food or feed commodity at harvest; residues above the tolerance make the crop illegal to sell.

Related: FIFRA, Pesticide label and labeling
Pesticide label and labeling

The label is the printed information attached to the pesticide container; labeling includes the label plus all other written or graphic material that accompanies or explains the product, such as brochures and supplemental directions.

Related: Pesticide misuse, Signal word
Pesticide misuse

Using a pesticide in a way that is inconsistent with its label or with FIFRA requirements; misuse is a violation of federal and Florida law and can result in civil or criminal penalties.

Related: Pesticide label and labeling, FIFRA
Worker Protection Standard

An EPA regulation that protects agricultural workers and pesticide handlers by requiring safety training, notification of applications, decontamination supplies, and limits on entry into treated areas.

Related: Restricted entry interval, Personal protective equipment, Safety Data Sheet
Restricted entry interval

The period after a pesticide application during which entering the treated area is prohibited without required protective equipment, as stated on the product label.

Related: Worker Protection Standard, Personal protective equipment
Personal protective equipment

Clothing and gear such as gloves, coveralls, boots, respirators, and eye protection that the label requires a handler to wear to reduce pesticide exposure.

Related: Signal word, Exposure route
Signal word

A word on the label, either DANGER, WARNING, or CAUTION, that indicates the relative acute toxicity of the product, with DANGER signaling the greatest hazard to people.

Related: LD50, Personal protective equipment
LD50

The dose of a pesticide, usually expressed in milligrams per kilogram of body weight, that kills half of a test animal population; lower values mean greater acute toxicity.

Related: Signal word, Cholinesterase inhibition
Cholinesterase inhibition

The blocking of an enzyme needed for normal nerve function by organophosphate and carbamate insecticides, which can cause poisoning and is monitored by blood tests in exposed workers.

Related: SLUDGE, Personal protective equipment
SLUDGE

A memory aid for common signs of organophosphate or carbamate poisoning: salivation, lacrimation, urination, diarrhea, gastrointestinal upset, and emesis (vomiting); these signs call for immediate medical attention.

Related: Cholinesterase inhibition, Exposure route
Safety Data Sheet

A document from the manufacturer summarizing a product's hazards, first aid, handling, and spill response; it supplements but does not replace the pesticide label as a source of directions.

Related: Signal word, Personal protective equipment
Secondary containment

A barrier or structure, such as a curbed floor or tub, placed under pesticide containers so leaks and spills are captured instead of reaching soil, drains, or water.

Related: Point-source pollution, Triple rinsing
Triple rinsing

A container-cleaning procedure in which the empty pesticide container is filled about one-third full, rinsed three times with the rinse water added to the spray tank, then punctured and recycled or disposed of properly.

Related: Secondary containment, Point-source pollution
Exposure route

The way a pesticide enters the body: through the skin (dermal), mouth (oral), lungs (inhalation), or eyes; dermal exposure is the most common route for pesticide handlers.

Related: Personal protective equipment, Cholinesterase inhibition
Spray drift

The movement of pesticide spray, dust, or vapor off the target site by air currents, which can injure non-target plants, animals, and people and may violate the label.

Related: Volatilization, Phytotoxicity
Volatilization

The conversion of a liquid or soil-bound pesticide into a vapor that can move off-site; it is increased by high temperatures, low humidity, and windy conditions.

Related: Spray drift, Persistence and half-life
Leaching

The downward movement of a pesticide through the soil with water, which can contaminate groundwater, especially when the product is highly soluble and persistent.

Related: Runoff, Persistence and half-life
Runoff

The movement of pesticide-contaminated water across the soil surface into ditches, streams, or ponds, often after rain or irrigation on sloped or compacted ground.

Related: Leaching, Point-source pollution
Bioaccumulation

The buildup of a pesticide in an organism's body over time because it is taken in faster than it is eliminated; the chemical can then be passed along the food chain.

Related: Persistence and half-life, Runoff
Persistence and half-life

Persistence is how long a pesticide remains active in the environment; it is often described by half-life, the time required for half of the applied amount to break down.

Related: Leaching, Bioaccumulation
Phytotoxicity

Injury to plants caused by a pesticide, showing as leaf burn, stunting, discoloration, or distortion; it may result from overdosing, drift, tank contamination, or sensitive varieties.

Related: Spray drift, Adjuvant
Point-source pollution

Pollution that comes from a specific, identifiable place such as a mixing pad, spill, or container dump site, rather than being spread broadly across the landscape.

Related: Secondary containment, Runoff
Integrated pest management

A decision-making approach that combines pest identification, monitoring, thresholds, sanitation, biological and cultural controls, and judicious pesticide use to manage pests with the least risk.

Related: Action threshold, Biological control, Pesticide resistance
Action threshold

The pest population level at which control action is needed to prevent unacceptable damage or loss; scouting counts are compared with this threshold before treating.

Related: Integrated pest management, Pesticide resistance
Pesticide resistance

The inherited ability of a pest population to survive a pesticide dose that once killed it; it develops fastest when the same mode of action is used repeatedly.

Related: Mode of action, Integrated pest management
Mode of action

The way a pesticide interferes with a pest's biology, such as blocking a nerve signal or inhibiting an enzyme; knowing it helps rotate products and manage resistance.

Related: Pesticide resistance, Adjuvant
Biological control

The use of living natural enemies such as predators, parasites, and pathogens to reduce pest populations; it works best alongside other IPM tactics and careful pesticide selection.

Related: Integrated pest management, Action threshold
Calibration

The process of measuring and adjusting application equipment so it delivers the intended amount of pesticide uniformly over a known area, verified by collecting and measuring nozzle output.

Related: Flat-fan nozzle, Adjuvant
Flat-fan nozzle

A nozzle type that produces a tapered, fan-shaped spray pattern and is commonly used for broadcast herbicide and insecticide applications on boom sprayers.

Related: Calibration, Spray drift
Adjuvant

A chemical added to the spray tank to improve pesticide performance, such as a surfactant that helps the spray stick to and spread over leaf surfaces.

Related: Calibration, Spray drift
Preemergence herbicide

A herbicide applied to the soil before weeds emerge, forming a barrier that kills germinating seedlings; it usually provides little control of already established weeds.

Related: Integrated pest management, Mode of action
Fumigant

A pesticide that forms a gas and is used in enclosed spaces or under sealed covers to control pests in soil, structures, or stored products; it requires special training and equipment.
