IPM - CORRECT ANSWER Integrated Pest Management; Goals are provide
economical pest control/protect the environment
Not The Goal Of IPM - CORRECT ANSWER Elimination of all pests
Economic threshold/action threshold - CORRECT ANSWER Number of pests per
plant of amount of damage to plant at which control measures should begin
economic injury level - CORRECT ANSWER breakeven point which the cost of
pest control equals the revenue loss caused by pest
aesthetic injury level - CORRECT ANSWER number of pests that might cause
enough damage to the appearance of a plant to warrant the cost of control
scouting - CORRECT ANSWER key to a successful IPM program
cultural control - CORRECT ANSWER improves plant health so that plants are
able to compete better against pests; soil preparation, fertility, proper planting, plant
selection, crop rotation
mechanical control - CORRECT ANSWER physically eliminates the weed;
hoeing, weed pulling, mowing, hand picking
biological control - CORRECT ANSWER uses living organisms to reduce pest
populations; predators, parasites, pest disease
preventative control - CORRECT ANSWER helps prevent entry and spread of
pests; quarantines inspections, certified seed, cleaning equipment
chemical control - CORRECT ANSWER herbicides, insecticides, fungicides,
repellents, fumigants
insect head - CORRECT ANSWER contains sensory organs, mouth parts and
brain
insect thorax - CORRECT ANSWER provides locomotion, legs and wings

noninfectious diseases - CORRECT ANSWER result of unfavorable growing
conditions; cannot be transmitted from plant to plant
infection diseases - CORRECT ANSWER caused by various pathogens; multiply
and transmitted from plant to plant
fungi - CORRECT ANSWER spores spread by rain, wind, insects, seeds; leaf
spots/root rots
bacteria - CORRECT ANSWER microscopic single celled organisms. Cannot
move by themselves; only enter through wounds or small openings; crown gall, soft
rot
nematodes - CORRECT ANSWER microscopic roundworms that reproduce by
eggs; spread by anything that moves infected plants parts or infested soil
viruses - CORRECT ANSWER submicroscopic pieces of DNA/RNA; spread by
insects/seed; mosaic/mottles
