,Q1. A landowner in Georgia notices extensive resin flow and boring dust on the trunk of a mature
loblolly pine. The tree is declining rapidly. Which pest is most likely responsible, and what primary
management action is recommended to prevent spread to adjacent trees?
A. Southern pine beetle; immediate salvage harvest and removal of infested trees.
B. Ips engraver beetle; apply prophylactic insecticide to surrounding trees.
C. Black turpentine beetle; install pheromone traps to monitor population.
D. Nantucket pine tip moth; prune and destroy affected branches.
Correct Answer: A. Southern pine beetle; immediate salvage harvest and removal of infested trees.
Rationale: The symptoms (resin flow, boring dust, rapid decline) are classic for southern pine beetle
(Dendroctonus frontalis). Because it can quickly kill trees and mass attack, immediate salvage and
removal of infested trees is crucial to stop the infestation from spreading. Ips and black turpentine beetles
typically attack stressed or recently cut trees, not necessarily with such rapid decline; tip moth attacks
new growth, not trunks.
Why Wrong:
B - Ips engraver beetles usually attack stressed or recently cut trees and are less aggressive;
prophylactic insecticide is not a primary response.
C - Black turpentine beetle attacks at the base and causes slower decline; removal is not as urgent.
D - Nantucket pine tip moth attacks shoots and does not produce resin flow on the trunk.
Reference: Georgia Forest Pest Control Manual, 2024, Chapter 4: Pine Bark Beetles.
Q2. A county extension agent in Georgia receives a report of wilting, browning leaves on a collection
of live oaks (Quercus virginiana) near a residential area. Laboratory tests confirm the presence of
Phytophthora ramorum. Which of the following is the most appropriate regulatory action?
A. Issue a quarantine and begin eradication of all oaks within 100 meters.
B. Apply a phosphonate fungicide to all nearby oaks and monitor.
C. Remove only symptomatic trees to reduce inoculum and restrict movement of host material.
D. Conduct aerial spraying of copper fungicides to prevent spread.
Correct Answer: A. Issue a quarantine and begin eradication of all oaks within 100 meters.
Rationale: Phytophthora ramorum is the causative agent of sudden oak death (SOD), a federally
regulated pathogen. Upon detection, immediate quarantine and eradication (removal of infected and
possibly adjacent host trees) are mandated to prevent establishment in new areas. Phosphonates have
limited efficacy once infection is confirmed; removal alone is insufficient without quarantine. Aerial
copper sprays are not effective against this aerial blight.
Why Wrong:
B - Phosphonate treatments are used prophylactically, not as a primary regulatory response to a
confirmed outbreak.
C - Only removing symptomatic trees without a quarantine allows for undetected spread; regulations
require quarantine and broader removal.
D - Copper fungicides are not effective against P. ramorum and are not part of the regulatory
protocol.

,Q3. An aerial applicator plans to spray a carbaryl formulation to control gypsy moth (Lymantria
dispar) in a hardwood forest adjacent to a stream. Which of the following best describes the
required buffer zone and application conditions to minimize drift and protect aquatic life?
A. No buffer needed if using a drift-reducing nozzle; apply when wind speed is below 10 mph.
B. A 200-foot no-spray buffer from the stream; apply when wind speed is 3-10 mph and temperature
inversion is absent.
C. A 500-foot buffer and only apply during early morning calm conditions.
D. Buffer of 100 feet and use an anti-drift adjuvant regardless of wind speed.
Correct Answer: B. A 200-foot no-spray buffer from the stream; apply when wind speed is 3-10
mph and temperature inversion is absent.
Rationale: Carbaryl is highly toxic to aquatic invertebrates. Georgia and EPA regulations require a
200-foot buffer from water bodies for aerial applications, and application must occur under stable
atmospheric conditions (no inversion) with winds between 3-10 mph to minimize off-target drift. Option A
is too permissive; C's 500-foot buffer is excessive unless specified; D ignores wind restrictions.
Why Wrong:
A - Drift-reducing nozzles help but do not eliminate the need for a buffer; wind speed over 10 mph
increases drift risk.
C - 500 feet is not the standard buffer; early morning may have inversion that reduces dispersion.
D - Anti-drift adjuvants are not a substitute for required buffer and wind speed limits.

Guidelines.
Q4. An invasive species management team is evaluating the use of the herbicide glyphosate for
controlling Chinese privet (Ligustrum sinense) in a riparian zone. Which of the following
application methods is most likely to minimize non-target impact while achieving effective control?
A. Aerial broadcast application at a low rate.
B. Basal bark treatment using a 20% glyphosate solution in oil.
C. Cut-stump treatment with a 50% glyphosate solution applied immediately after cutting.
D. Foliar spot spraying with a 2% glyphosate solution during the growing season.
Correct Answer: C. Cut-stump treatment with a 50% glyphosate solution applied immediately after
cutting.
Rationale: Cut-stump treatment applies herbicide directly to the cut surface, minimizing drift and
off-target exposure, especially in sensitive riparian areas. Basal bark treatment is suitable for thin-barked
species but can still contact non-target plants. Foliar spray risks drift to non-target vegetation, and aerial
broadcast is inappropriate. Chinese privet responds well to cut-stump application, and the high
concentration prevents resprouting.
Why Wrong:
A - Aerial broadcast would cause significant drift and harm non-target riparian vegetation.
B - Basal bark treatment is less targeted than cut-stump and may not be as effective on large stems;
also uses oil that can contaminate water.
D - Foliar spot spraying has higher risk of off-target drift, especially near water.

, Q5. A forest manager in Georgia observes that several loblolly pines have yellowing needles and
reduced height growth. Soil analysis indicates low nitrogen and phosphorus. The trees also show
signs of a root-feeding pest. Which of the following best describes the synergistic interaction between
the soil condition and pest?
A. Nutrient deficiency directly kills the pest, reducing damage.
B. The pest is attracted to trees with nutrient imbalances, and the stress from deficiency makes the
trees more susceptible to pest attack.
C. The pest introduces a fungus that enhances nutrient uptake, benefiting the tree.
D. The nutrient deficiency encourages predators of the pest, reducing pest populations.
Correct Answer: B. The pest is attracted to trees with nutrient imbalances, and the stress from
deficiency makes the trees more susceptible to pest attack.
Rationale: Stressed trees due to nutrient deficiency are more vulnerable to pest attack. Many forest pests,
such as root-feeding weevils, are attracted to trees with compromised defenses. The interaction is
synergistic: the deficiency weakens the tree, and the pest further damages the root system, exacerbating
nutrient uptake issues. Option A is incorrect because deficiency does not kill the pest; C and D are not
typical interactions.
Why Wrong:
A - Nutrient deficiency does not kill most pests; it often favors them.
C - Pests generally do not introduce beneficial fungi for nutrient uptake; many pests are vectors of
pathogens.
D - Nutrient deficiency does not typically enhance predator populations.
Reference: Forest Health Handbook, 2022, Chapter on Pest-Host Interactions.
Q6. A landowner plans to harvest a stand of southern pines and wants to prevent infestation by the
black turpentine beetle (Dendroctonus terebrans) during harvest operations. Which of the following
strategies is most effective for minimizing beetle attraction to freshly cut stumps and damaged
trees?
A. Apply a 1% solution of permethrin to all stump surfaces within 2 hours of cutting.
B. Delay harvest until winter when beetle populations are dormant.
C. Bury stumps immediately after cutting to reduce volatiles.
D. Place pheromone-baited traps around the perimeter to intercept dispersing beetles.
Correct Answer: A. Apply a 1% solution of permethrin to all stump surfaces within 2 hours of
cutting.
Rationale: Black turpentine beetles are attracted to wounds and volatile terpenes released from fresh
stumps. Rapid application of a registered insecticide (e.g., permethrin) to stump surfaces creates a
chemical barrier that kills or repels beetles before they colonize. Burying stumps is impractical; winter
harvest reduces but does not eliminate risk; pheromone traps are primarily used for monitoring, not
prevention in active harvests.
Why Wrong:
B - Winter harvest reduces beetle activity but not enough; beetles can still be active on warm days,
and stumps remain attractive.
C - Burying stumps is logistically infeasible in most operations and may not be timely.
D - Pheromone traps may attract beetles to the area, increasing risk; they are not a primary
prevention method.
