MASSACHUSETTS PESTICIDE CORE REVIEWS
ANSWERS AND QUESTIONS SET A+
✔✔Dry Flowable (DF) - ✔✔See WATER DISPERSIBLE GRANULE
✔✔Dust (D) - ✔✔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
✔✔Economic Threshold (ET) - ✔✔The pest population density (number of pests per
unit area) at which control measures are needed to prevent the pest from causing
economic injury.
✔✔Emulsifiable Concentrate (EC) - ✔✔A pesticide formulation produced by mixing an
active ingredient and an emulsifying agent in a suitable petroleum solvent. When
combined with water, a milky emulsion is usually formed.
✔✔Emulsion - ✔✔A mixture of two liquids that are not soluble in each another. One is
suspended as a very small droplet in the other with the aid of an emulsifying agent.
✔✔Enclosed cab - ✔✔Tractor cabs, cockpits, and truck/vehicle cabs that surround the
occupant(s) and may help to prevent exposure to pesticides as long as all doors,
hatches or windows are kept closed during the pesticide application
✔✔Endangered species - ✔✔Plant or animal species whose population had been
reduced to near extinction
✔✔Environment - ✔✔All the features that surround and affect an organism or group of
organism, including the air, soil, water, and other living things. For people and many
pests, it included indoor areas as well as outdoor
, ✔✔Evironmental Protection Agency (EPA) - ✔✔The federal agency responsible for
implementing pesticide rules and regulations and registering pesticides
✔✔EPA Establishment Number - ✔✔A number assigned to each pesticide production
facility by the 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 registered pesticide product
by the EPA
✔✔Eradicant - ✔✔a systemic fungicide that controls existing infections
✔✔Eradication - ✔✔A pest management strategy that attempts to eliminate all
members of a pest population from a defined area.
✔✔Exposure - ✔✔Unwanted contact with pesticides or pesticide residue by people or
other organisms
✔✔Extended - ✔✔Adjuvant that increases retention of a pesticide on the treated
surface by slowing evaporation and inhibiting photodegradation
✔✔FIFRA - ✔✔Federal Insecticide, Fungicide, and Rodenticide Act ,the primary federal
pesticide law
✔✔Flowable (F or L) - ✔✔a pesticide formulation in which very finely ground solid
particles, composed of both active and inert ingredients, are suspended in a liquid
carrier
✔✔Foaming agent - ✔✔An adjuvant designed to reduce pesticide drift by producing a
thick foam.
✔✔Fog Treatment - ✔✔The application of a pesticide as a fine mist or fog.
✔✔Foliar - ✔✔Refers to pesticide applications to the leaves of plants.
✔✔Food chain - ✔✔Sequence of species within an ecological community, each
member of which serves as a food source for the species next higher in the chain
✔✔Formulation - ✔✔A 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
