The unique identifier printed on a pesticide label showing the product has been approved by the U.S. Environmental Protection Agency for the uses listed.

The printed directions, warnings, and use restrictions attached to or accompanying a pesticide container; it is a legally binding document that must be followed.

All written or graphic material that accompanies a pesticide product or is referenced on the label, including supplemental leaflets, brochures, and worker safety information.

A required word on the label indicating the relative acute toxicity of a product: DANGER-POISON, DANGER, WARNING, or CAUTION, listed from most to least hazardous.

Label language describing hazards to people, animals, or the environment and the protective measures needed, such as required personal protective equipment.

Clothing and gear such as gloves, respirators, goggles, and coveralls that the label requires or that applicators wear to reduce exposure to pesticides.

A device worn over the face that filters or supplies clean air to protect the lungs from pesticide dusts, mists, or vapors when the label requires respiratory protection.

Contact between a pesticide and a person's skin, eyes, lungs, or mouth through dermal, inhalation, or oral routes, which can cause acute or chronic health effects.

A type of pesticide, mainly organophosphates and carbamates, that disrupts nerve signaling by blocking the enzyme cholinesterase; repeated exposure can cause serious illness.

A document provided by the manufacturer summarizing a product's hazards, first aid, handling, and emergency information; it supplements but does not replace the label.

The movement of pesticide off the intended application site through the air, either as spray droplets or as vapor, potentially harming people, crops, or the environment.

Off-target movement of pesticide droplets carried by wind or air currents during and shortly after application; affected by droplet size, nozzle type, and weather.

An untreated area between an application site and a sensitive area such as a water body or home, required by some labels to reduce drift or runoff risk.

A location where pesticide exposure could harm people or the environment, such as schools, hospitals, water bodies, or habitat for threatened species.

A decision-making approach that combines monitoring, sanitation, biological control, and judicious pesticide use to manage pests economically while limiting environmental harm.

The pest population level at which the cost of control is justified by the damage the pest would otherwise cause, guiding when to treat.

Regular inspection of a crop or site to identify pests and determine their numbers, so control decisions rest on observed conditions rather than routine spraying.

Using natural enemies such as predators, parasites, or pathogens to suppress pest populations, often as part of an integrated pest management program.

The inherited ability of a pest population to survive a pesticide dose that would normally kill it, often developing when the same mode of action is used repeatedly.

The way a pesticide kills or controls a pest, such as disrupting a specific enzyme or nerve function; rotating among modes helps delay resistance.

The maximum legal residue level of a pesticide allowed on or in a food or feed commodity, established by EPA to protect public health.

The component of a sprayer that breaks liquid into droplets and shapes the spray pattern; its size and wear strongly affect application rate and drift.

The process of measuring and adjusting a sprayer so it delivers the intended amount of pesticide uniformly over a known area, protecting efficacy and reducing waste.

The amount of pesticide product or active ingredient applied per unit of area, such as gallons per acre or pounds per acre, as set by the label.

Mechanical or hydraulic mixing that keeps a pesticide formulation evenly suspended in the tank so the applied mixture stays at the correct concentration.

A procedure for rinsing an emptied pesticide container three times, adding each rinse to the spray tank, to remove residue before disposal or recycling.

The bottle, jug, or drum holding a pesticide; after use it must be rinsed and disposed of or recycled according to label directions and state rules.

The required handling of empty pesticide containers, such as rinsing, puncturing, and delivering them to an approved recycling or disposal program.

Label restrictions and use practices designed to prevent pesticides from harming federally listed threatened or endangered plants and animals and their habitat.

Movement of pesticides downward through soil into underground water supplies, influenced by soil type, rainfall, irrigation, and a chemical's persistence and solubility.

The downward movement of a pesticide through soil with water, which can carry chemicals into groundwater and is greater in sandy soils and with heavy rain.
