GEORGIA PESTICIDE EXAM -
CATEGORY 24 QUESTIONS WITH
CORRECT ANSWERS
insecticides for chinch bugs - Answer-should be on leaf surface and not watered in
insecticides for white grubs or billbugs - Answer-need to get into thatch layer, so apply
water until top inch of soil under thatch is wet
pitfall traps - Answer-work well for monitoring adult billbugs
pheromone traps - Answer-can attract more insects than they actually trap
apply an insecticide - Answer-when insect is at its most vulnerable stage
Bacillus thuringiensis (Bt) - Answer-soil bacterium that controls caterpillars
milky spore disease - Answer-bacterium that is only effective against Japanese beetle
grubs
mole crickets have - Answer-only one generation per year
contact herbicide - Answer-kills or injures only the part of the plant that is touched by the
spray
systemic herbicide - Answer-absorbed by plant and translocated to other parts of the
plant
major cause of herbicide failure - Answer-application errors
pre-emergence herbicides - Answer-must be watered in or rained on
postemergence herbicides - Answer-work best in bright sunlight
annual weeds - Answer-grow, flower, go to seed, and die within 12 months
biennial weeds - Answer-Form a rosette of leaves the first year and flower the next.
(easier to kill in first year, but rosette is often overlooked, as it is close to the ground)
perennial weeds - Answer-can live indefinitely (dandelion, white clover)
chickweed and henbit (winter annuals) - Answer-best controlled between mid-fall and
early winter
, disorder - Answer-abnormality of structure or function caused by unfavorable growing
conditions -- not infectious and cannot be spread from plant to plant
disease - Answer-caused by pathogens such as fungi, bacteria and viruses which can
multiply and spread from plant to plant
disease pyramid - Answer-diagram of the four factors needed for a disease to develop
(susceptible host, pathogen, favorable environment, and time)
protectant fungicides - Answer-coat a susceptible plant as a barrier; not absorbed by the
plant, so they don't protect new plant growth; need to be re-applied every 5-10 days.
systemic fungicides - Answer-circulate within the plant, so can control fungi already in
the plant; will not wash off by rain
stand symptoms - Answer-symptoms on the turf that are evident from a distance (such
as patches or rings)
plant symptoms - Answer-evident on the individual plant or plant parts (leaf spots, stem
lesions, crown and root rot)
fairy ring - Answer-green arcs or circles of turf caused by mushrooms or puffball fungi;
very difficult to control
large patch is encouraged by: - Answer-excessive nitrogen in fall and spring, wet
weather, low mowing height
gray leaf spot is common in - Answer-St. Augustinegrass
Spring dead spot is a serious disease of - Answer-Bermudagrass
nematodes - Answer-miscroscopic roundworms that harm plants by feeding on the roots
spring dead spot occurs - Answer-after winter dormancy
This cultural practice increases the risk of several turf diseases - Answer-excessive
nitrogen fertilizer
Hardiness Zones - Answer-a geographically-defined zone in which a specific category
of plant life is capable of growing and withstanding the minimum temperatures of that
zone.
Cultural control methods - Answer-placement of plants, irrigation, fertilization (choosing
correct site is key)
