,Q1. A loblolly pine stand (15 years old) exhibits sparse crowns and resin flow on lower boles. Bark
samples reveal dark brown to black, irregularly shaped cankers with fruiting bodies. Which
pathogen is most likely responsible, and what cultural practice is most effective for long-term
management?
A. Fusiform rust (Cronartium quercuum f. sp. fusiforme); prune galls and maintain high stand density.
B. Annosum root rot (Heterobasidion irregulare); thin stands to increase air circulation.
C. Pitch canker (Fusarium circinatum); remove infected trees and avoid wounding during thinning.
D. Diplodia tip blight (Diplodia pinea); apply copper fungicide in spring.
Correct Answer: C. Pitch canker (Fusarium circinatum); remove infected trees and avoid wounding
during thinning.
Rationale: Pitch canker (Fusarium circinatum) causes resin flow, cankers, and crown dieback in pines.
Cultural control focuses on preventing wounds (insect, mechanical) and removing infected trees, as no
chemical cure exists. Fusiform rust produces galls, not resin flow. Annosum root rot causes root decay
and windthrow. Diplodia tip blight affects shoots, not bole cankers.
Why Wrong:
A - Fusiform rust causes spindle-shaped galls, not resin flow from cankers, and pruning galls is not
primary management.
B - Annosum root rot causes root decay and windthrow, not bole cankers with resin flow.
D - Diplodia tip blight affects new shoots and cones, not lower bole cankers with resin flow.

Service, Pitch Canker Management Guide.
Q2. A landowner plans to apply imidacloprid via soil injection to control hemlock woolly adelgid
(Adelges tsugae) in a riparian buffer zone. Considering environmental fate and Alabama
regulations, which additional requirement is mandatory?
A. Obtain a National Pollutant Discharge Elimination System (NPDES) permit for pesticide
application near waters of the U.S.
B. Imidacloprid is prohibited within 100 feet of any water body; use only foliar spray with
horticultural oil.
C. Apply only during dormant season to minimize off-target movement; no permit needed.
D. Use a granular formulation only; soil injection is not allowed within 50 feet of streams.
Correct Answer: A. Obtain a National Pollutant Discharge Elimination System (NPDES) permit for
pesticide application near waters of the U.S.
Rationale: Under the Clean Water Act, pesticide applications near waters of the U.S. may require an
NPDES permit if there is a discharge to water. Imidacloprid is highly mobile and toxic to aquatic
invertebrates. B is false because imidacloprid is not prohibited outright but requires mitigation. C is false
because dormant season does not eliminate permit requirements. D is false; soil injection is allowed with
proper setbacks.
Why Wrong:
B - Imidacloprid is not prohibited within 100 feet; it is allowed with best management practices to
reduce runoff.
C - Dormant season application does not exempt from NPDES permit requirements if discharge
occurs.
D - Granular formulations are not required; soil injection is permissible with appropriate setbacks.

Permit (2023).

, Q3. An outbreak of southern pine beetle (Dendroctonus frontalis) is detected in a mixed
pine-hardwood stand. The infestation covers 5 acres with 20 active spots. Using the Alabama IPM
threshold of 1 active spot per 10 acres, which action is recommended?
A. Implement a salvage harvest of all pines in the stand to prevent spread.
B. Apply a preventive carbaryl spray to uninfested pines within 100 meters of active spots.
C. Cut and remove infested trees within each spot, plus a buffer of uninfested trees; no salvage of
entire stand.
D. Do nothing; the infestation will naturally collapse when beetle populations exceed carrying
capacity.
Correct Answer: C. Cut and remove infested trees within each spot, plus a buffer of uninfested
trees; no salvage of entire stand.
Rationale: The Alabama threshold for control is >1 active spot per 10 acres. With 20 spots in 5 acres (4
spots/acre), suppression is warranted. Recommended action is spot control: cut and remove infested trees
plus a buffer (often 1-2 chains). Salvage of all pines (A) is excessive. Preventive spray (B) is not primary
for active outbreaks. Natural collapse (D) risks extensive mortality.
Why Wrong:
A - Salvage of all pines is too aggressive; spot control is standard unless infestation is severe and
widespread.
B - Preventive sprays are used before attack; during active outbreak, removal of infested trees is
primary.
D - Natural collapse is unreliable and could lead to extensive tree mortality across the stand.

et al., J. Forestry.
Q4. A forest manager observes extensive defoliation on water oaks (Quercus nigra) in June. Larvae
are yellow-green with black tubercles and two prominent black stripes on the back. Which insect is
present, and what is the recommended intervention?
A. Fall webworm (Hyphantria cunea); remove webs and apply Btk if populations are high.
B. Yellow-necked caterpillar (Datana ministra); no control needed unless tree health is at risk.
C. Variable oakleaf caterpillar (Lochmaeus manteo); apply chemical insecticide immediately.
D. Oak lecanium scale (Parthenolecanium quercifex); apply dormant oil in winter.
Correct Answer: B. Yellow-necked caterpillar (Datana ministra); no control needed unless tree
health is at risk.
Rationale: Yellow-necked caterpillar larvae are yellow-green with black stripes and feed in groups,
skeletonizing leaves. Defoliation in early summer can stress trees, but oaks often recover. Control is
recommended only if tree health is compromised (e.g., drought, previous defoliation). Fall webworm
builds webs at branch tips. Variable oakleaf caterpillar has different markings. Scale insects are sessile,
not defoliating larvae.
Why Wrong:
A - Fall webworm builds silken webs enclosing foliage, and larvae are hairy, not with black stripes.
C - Variable oakleaf caterpillar has a green body with yellow stripes, not black stripes, and
immediate chemical control is rarely warranted.
D - Oak lecanium scale is a soft scale that does not cause defoliation; it produces honeydew.
