Answers with 100% Correct Answers Already Graded A+
pest - (ANSWER)any insect, mite, rodent,nematode, fungus, weed, or other plant or animal that is
injurious to the health of humans, animals, or to the environment
economic threshold - (ANSWER)number of pests per plant or the amount of damage to a plant at which
point control measures should be begun
economic injury level - (ANSWER)break-even point at which the cost of pest control equals the revenue
loss caused by a pest
aesthetic injury level - (ANSWER)number of pests that might cause enough damage to the appearance of
a plant to warrant the cost of control
cultural control - (ANSWER)improves crop health in order to make the crop better able to compete
against pests. for example, a dense, vigorous stand of turfgrass that has been properly fertilized and
mowed is the best defense against invading weeds. selecting plants that are resistant to insects or
disease pathogens is another cultural control practice
mechanical control - (ANSWER)physically eliminates the best. hand pulling, hoeing, rotary hoeing,
cultivating, mowing, and aquatic weed harvesting can control weeds and minimize the needs for
herbicides
biological control - (ANSWER)the use of living organisms to reduce pest populations to economically
acceptable levels. insects,diseases, or parasitic plants can be used as control agents to reduce weed
competitiveness. examples for pest control-parasitic wasps to control alfalfa weevil and b.t. to control
corn borers. triploid amur carp, have been used successfully in some aquatic areas.
chemical control - (ANSWER)may be an integral part of an ipm program. quick effective short term,
consider non-chemical methods first, consider environmental impacts, apply at proper time and site
plant pests - (ANSWER)are generally categorized as insects and other animals, weeds, or diseases. first
step in pest control is identification of the pest

miticides - (ANSWER)mites
desiccants - (ANSWER)plants to be dehydrated
active ingredients - (ANSWER)toxic to the pest. examples: glysophate, carbaryl, propiconazole
inactive ingredients - (ANSWER)example: solvent or dry carrier
adjuvant- - (ANSWER)a chemical that modifies a pesticides physical properties and/or enhances
performance
drift reduction additives - (ANSWER)increase droplet size and reduce drift
spreaders - (ANSWER)help individual spray droplets spread out on the treated surface
stickers - (ANSWER)improve pesticide adherence to the treated surface
penetrant - (ANSWER)improves systematic pesticide penetration in the treated surface
jar test - (ANSWER)perform a jar test physical compatibility is a concern
selective pesticides - (ANSWER)control some related pests, but not others. example-2,4-D to control
broadleaf weeds in grasses
non-selective pesticides - (ANSWER)control all related pests. example-glyphosate to control all weeds
along a fence row
contact pesticides - (ANSWER)do not move within the plant. expamle-daconil fungicide, sevin insecticide,
gramoxone herbicide
