Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) - ANSWERRegulates the
production, transporation, sale, use, and disposal of all pesticides.
Residues - ANSWERPesticides may remain in small amounts in or on fruits,

,Preharvest interval - ANSWERPart of the pesticide label that defines the number of
days after application of a pesticide before a crop can be harvested.
Food Quality Protection Act (FQPA) - ANSWERFederal law that significantly altered
portions of both FIFRA and FFDCA. Changes included in the Act are revised definitions
for safe pesticide tolerances for raw and processed foods.
Worker Protection Standard (WPS) - ANSWERA set of regulations from the EPA aimed
at reducing the risk of pesticide poisonings, injuries, and exposure to agricultural
workers and handlers.
Endangered Species Act (ESA) - ANSWERA program for the
Endangered Species in Iowa - ANSWER7 animals, 5 plant species
Endangered species - ANSWERA species that is in danger of extinction throughout all
or a significant portion of its range.
Threatened species - ANSWERA species that is likely to become endangered within the
foreseeable future throughout all or a significant portion of its range.
Rinsates - ANSWERThe solution of water or oil and pesticide left after rinsing a tank;
rinse water.
Hazardous Waste - ANSWERA solid, liquid, or a contained gaseous material that is no
longer used or that no longer serves the purpose for which it was produced, and could
pose dangers to human health and then environment after it is discarded.
Resource Conservation and Recovery Act (RCRA) - ANSWERFederal law regulating
the transport, storage, treatment, and disposal of hazardous wastes.
Concentration - ANSWERThe amount of active ingredient in a given volume or weight
of a pesticide formulation.
Apiaries - ANSWERBee yards
Drift - ANSWERThe movement of pesticides through the air to nontarget areas either as
solid or liquid particles or as vapors.
Secondary Containment - ANSWERAny structure used to prevent runoff or leaching of
pesticide materials.
Pest - ANSWERAny living species whose activities cause economic losses to your
possessions, directly threaten your health, or are annoying.
, Integrated Pest Management (IPM) - ANSWERAn approach to controlling a specific
pest in a specific setting that makes use of current pest information, regular monitoring,
and record-keeping to determine if and when action against the pest is needed.
Components of IPM - ANSWER1: Identify the pest and understand its biology
2: Set up a monitoring system
3: Know the available control strategies
4: Implement IPM
5: Record and evaluate results
Host - ANSWERA plant or animal on which an organism lives.
Life cycles - ANSWERThe progression of stages in the development of an organism.
Monitoring/scouting - ANSWERPlanned, regular inspection of a crop, ornamental
planting, landscape, or structure for the purpose of detecting pests, pest damage, or
conditions conductive to pests or pest damage.
Economic threshold - ANSWERThe population density of a pest at which control
measures should be initiated to prevent an increasing pest population from reaching the
economic injury level.
Economic Injury Level - ANSWERThe population density of a pest causes a reduction in
the value of the crop that equals the cost of the control.
Aesthetic Threshold - ANSWERDamage level that is unacceptable to the viewer.
Action Threshold - ANSWERThe pest level at which some type of pest management
action should be taken.
Natural enemies - ANSWERThe predators, pathogens, and parasites that attack pest
species.
Biological control - ANSWERControl by predators, pathogens, and parasites that are
either naturally occurring or introduced.
Mechanical control - ANSWERControl of pests by physical means such as the use of
cultivators, mowers, and traps.
Cultural control - ANSWERControl measures including modification of the planting,
cultivating, and harvesting of plants aimed at prevention of pest damage.
Sanitation - ANSWEREliminating potential sources of infestation to prevent a pest
problem.
