✔✔Demonstration and Research - ✔✔A type of applicator certification or license for an
individual who applied experimental or restricted use pesticides for research purposes
under state or federal "Experimental Use Permits"
✔✔Deposit - ✔✔The amount of a pesticide on the treated surface after application
✔✔Dermal toxicity - ✔✔The ability of a pesticide to cause injury to a human or animal
when absorbed through the skin
✔✔Desiccant - ✔✔A chemical that promotes drying or loss of moisture from a leaf or
other plant part.
✔✔Detoxify - ✔✔To render a pesticides active ingredient or other poisonous chemical
harmless
✔✔Diagnosis - ✔✔The positive identification of problem and its cause
✔✔Diluent - ✔✔Any liquid or solid material used to dilute
✔✔Dip - ✔✔Complete or partial immersion of a plant or object in a pesticide.
✔✔Disinfectant - ✔✔1) A Chemical or other agent that kills or inactivates disease-
production microorganisms in animals, seeds, or other plant part. 2) Chemicals used
clean or surface-sterilize inanimate objects.
✔✔Dispersing agent - ✔✔An adjuvant that facilitates mixing and suspension of a
pesticide formulation in water.
✔✔Dormant spray - ✔✔A pesticide application to plants made in late winter or early
spring prior to the resumption of active growth.
✔✔Dose, Dosage - ✔✔Quantity of pesticide applied to a given area or target.
✔✔Drift - ✔✔The airborne movement of pesticide spray droplets, dust, or vapors
beyond the intended contact area.
✔✔Drift retardant - ✔✔An adjuvant added to a spray mixture to reduce drift.
✔✔Dust - ✔✔A finely ground, dry pesticide formulation containing a small amount of
active ingredient and a large amount of inert carrier or diluent such as clay or talc.
,✔✔Economic injury level - ✔✔The pest population density that causes losses equal to
the cost of control measures.
✔✔Economic threshold - ✔✔The level or density of a pest population where control
measures need to be applied to prevent the pest from reaching the economic injury
level.
✔✔Emulsifiable concentrate - ✔✔A pesticide formulation produced by dissolving the
active ingredient and an emulsifying agent in a suitable solvent. When added to water, a
milky emulsion is formed.
✔✔Emulsifying agent (emulsifier) - ✔✔A chemical that aids in the suspension of one
liquid in another which normally would not mix together.
✔✔Emulsion - ✔✔A mixture of two liquids that are not soluble nine one another. One is
suspended as very small droplets in the other with the aid of an emulsifying agent. Oil in
water is an example.
✔✔Encapsulated pesticide - ✔✔1) A pesticide formulation with the active ingredient
enclosed in capsules of polyvinyl of other synthetic materials; principally used for slow
release. 2) A method of disposal of pesticides and pesticide containers by sealing them
in a sturdy, water proof container to prevent leakage.
✔✔Endangered species - ✔✔Individual plants or animals with a population that has
been reduced to the extent that it is near extinction.
✔✔Environment - ✔✔All the features that surround and affect an organism or group of
organisms.
✔✔EPA - ✔✔Environmental Protection Agency. The federal agency responsible for
implementing pesticide rules and regulations and register ing pesticides.
✔✔EPA Establishment Number - ✔✔A number assigned to each pesticide production
plant by EPA. The number indicates the plant at which the pesticide product was
produced and must appear on all labels of that product.
✔✔EPA Registration Number - ✔✔A number assigned to a pesticide product by EPA
when the product s registered by the manufacturer or the designated agent. The
number must appear on all labels for a particular product.
✔✔Eradicant - ✔✔A chemical or other agent such as steam or heat used to eliminate
an established pest from a plant, animal, or specific area such as soil, water, or
buildings.
, ✔✔Eradication - ✔✔The complete elimination of a pest from a site.
✔✔Fetotoxic - ✔✔The ability of na substance to cause harm to na developing fetus, but
not necessarily cause deformities. (see Teratogenic)
✔✔Field scout - ✔✔A person who samples fields for pest infestations
✔✔Fifra - ✔✔The federal insecticide, Fungicide, and Rodenticide Act; a federal law
dealing with pesticide regulations and use.
✔✔Fit Check - ✔✔A positive or negative-type pressure test conducted by a pesticide
handler wearing a respirator ton ensure the device forms a complete seal around the
face and air cannot leak in or out along the edges. Also called a USER SEAL CHECK.
✔✔Fit Factor - ✔✔The ratio between the dust concentration in the surrounding air and
that inside a respirator.
✔✔Flowable - ✔✔a pesticide formulation in which a very finely ground solid particle is
suspended (not dissolved) in a liquid carrier.
✔✔Foaming Agent - ✔✔An adjuvant designed to reduce drift by causing a pesticide mix
to form a thick foam.
✔✔Foam Retardant - ✔✔An adjuvant usd to reduce the foaming of a spray mixture that
results from agitation.
✔✔Fog treatment - ✔✔The application of na pesticide as a fine mist or fog.
✔✔Food chain - ✔✔Sequence of species within a community, each member of which
serves as a food source for the species next higher in the chain.
✔✔Forecasting - ✔✔The prediction of pest incidence using weather, host, and
pathogen characteristics.
✔✔Formulation - ✔✔The pesticide product as purchased, containing a mixture of one or
more active ingredients, carriers (inert ingredients), and other additives diluted for safety
and ease of application.
✔✔Fumigant - ✔✔A pesticide that forms gases that are toxic to plant and animals when
absorbed or inhaled.
✔✔Fungi (plural of Fungus) - ✔✔Nonchlorophyll-bering plants, living as saprophytes or
parasites. Some infect and cause diseases in plants, animals, and humans or destroy
