,Q1. A landscape manager observes that an ornamental shrub (Pittosporum tobira) is infested with
soft brown scale (Coccus hesperidum). The infestation is localized to 10% of the plants in a 2-acre
commercial property. Ants are actively tending the scales. Which integrated pest management
strategy would be most appropriate as the first intervention?
A. Apply a soil drench of imidacloprid to all shrubs to prevent scale establishment
B. Release parasitic wasps (Metaphycus spp.) and manage ants with baits to reduce mutualism
C. Spray a broad-spectrum organophosphate (malathion) to eliminate both scales and ants
immediately
D. Prune and destroy all infested branches, then apply horticultural oil to the remaining shrubs
Correct Answer: B. Release parasitic wasps (Metaphycus spp.) and manage ants with baits to
reduce mutualism
Rationale: IPM prioritizes biological control and cultural practices. Releasing parasitic wasps targets
scales specifically, while ant management reduces scale protection, allowing natural enemies to work.
Option A is prophylactic and may harm non-targets; C is a broad-spectrum approach that disrupts
beneficials; D is too aggressive for a localized infestation and may not address ants.
Why Wrong:
A - Prophylactic soil drench is unnecessary for a localized infestation and may cause environmental
contamination.
C - Broad-spectrum organophosphates kill beneficial insects and are not recommended as first-line
IPM.
D - Pruning all infested branches is excessive for 10% infestation and does not address ant-scale
mutualism.

Landscape Maintenance. Ch. 4.
Q2. A certified applicator is applying a pesticide to control aphids on roses. The label states: 'Do not
apply within 50 feet of water bodies.' The property has a koi pond 30 feet from the rose bed. The
applicator decides to use a lower-rate application and a drift-reducing nozzle. Which regulatory
principle is the applicator violating?
A. The pesticide label is a legal document; any deviation from label instructions is a violation of
FIFRA
B. The applicator may use professional judgment to reduce rates as long as efficacy is maintained
C. Drift-reducing nozzles allow application within buffer zones if wind speed is below 5 mph
D. The 50-foot buffer applies only to aerial applications, not ground-based treatments
Correct Answer: A. The pesticide label is a legal document; any deviation from label instructions is
a violation of FIFRA
Rationale: Under FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act), pesticide labels are
legally binding. The buffer zone is mandatory regardless of equipment or rate adjustments. Options B and
C are false because label restrictions cannot be overridden by professional judgment or nozzle choice; D
is incorrect because the buffer applies to all applications unless specified otherwise.
Why Wrong:
B - Professional judgment cannot supersede label requirements; label is law.
C - Drift-reducing nozzles reduce but do not eliminate the need for buffer zones; label restrictions
are absolute.
D - The label does not specify aerial-only; it applies to all application methods.
