California Qualified Applicator License – Category E
(Forest Pest Control) exam COMPLETE QUESTIONS AND
DETAILED SOLUTIONS LATEST UPDATE THIS YEAR-JUST
RELEASED
California Qualified Applicator License – Category E (Forest Pest Control) exam, followed by 250
randomized, scenario-based multiple-choice questions with answers and rationales. No domain or
section headings are used.
SUMMARIZED EXAM TOPICS COVERED (POINT FORM)
• Forest Pests & Diseases: Insects: bark beetles (mountain pine beetle, western pine beetle, fir
engraver), defoliators (tussock moth, gypsy moth, western spruce budworm), wood borers
(flatheaded borers, longhorned beetles). Diseases: root diseases (Armillaria, Heterobasidion,
Phytophthora ramorum – sudden oak death), stem rusts (white pine blister rust), canker
diseases. Weeds: invasive plants (yellow starthistle, Scotch broom, French broom, thistles,
gorse).
• Integrated Pest Management (IPM): Monitoring (pheromone traps, visual surveys, aerial
detection surveys), action thresholds (economic injury level, pest population levels), biological
control (natural enemies – parasitoids, predators, pathogens), cultural practices (thinning,
prescribed burning, sanitation), chemical control (herbicides, insecticides, fungicides).
• Silviculture & Forest Management: Stand dynamics, tree species identification (pines, firs, oaks,
redwoods), forest health assessments, thinning (commercial, pre-commercial), salvage logging,
prescribed fire management, reforestation.
• Regulations & Laws: California Food & Agricultural Code (pesticide use), California Code of
Regulations Title 3 (pesticide use reporting), PRC 12000 (McAteer-Petris Act – coastal
protection), Endangered Species Act (consultation for listed species), Forest Practice Rules (of
CAL FIRE), timber harvesting plans (THP), NPDES permitting for forest activities (discharge to
water), ESA Section 7 and 10 consultations.
• Pesticide Application Methods: Aerial application (helicopter, fixed-wing), ground application
(backpack sprayers, mist blowers, side-mounted sprayers, airblast), granular application
(herbicides), stem injection (for individual tree treatment), basal bark application, stump
treatment, calibration of equipment, drift management, buffer zones.
• Environmental Protection: Endangered species (e.g., California condor, spotted owl, marbled
murrelet), watershed protection (surface water buffers, protection of riparian zones), sensitive
habitat, pollinator protection (insecticides in flowering vegetation), pesticide runoff mitigation,
groundwater protection.
• Worker Safety & Personal Protective Equipment (PPE): Respiratory protection (cartridge
respirators for pesticides, N95 for dust), chemical-resistant gloves, coveralls, eye protection,
heat stress prevention in forest environments, pesticide poisoning recognition,
decontamination, emergency response, WPS (Worker Protection Standard) for forest sites
(handlers and early entry workers).
• Pesticide Formulations & Toxicological Classifications: Signal words (Danger, Warning, Caution),
LD50, routes of exposure, fumigants (for wood borers), herbicide modes of action (growth
regulators, amino acid inhibitors), insecticide classes (organophosphates, pyrethroids,
neonicotinoids, avermectins). Adjuvants (surfactants, drift control agents, compatibility agents).
, Page 2 of 149
• Recordkeeping & Reporting: MDA/DPR Form (pesticide use reports) – due within 30 days of
application, retained for 2 years. Contents: date, product name, EPA registration number,
amount used, target pest, site (legal description or GPS), application method, weather
conditions, applicator certification number. Wood infestation reports (if applicable). Permit
requirements for restricted materials.
• Calibration & Application Calculations: Gallons per acre (GPA), miles per hour (MPH), nozzle
output (GPM), swath width, tank mixing order (water, wettable powders, emulsifiable
concentrates, surfactants). Label rates (amount of product per acre).
QUESTIONS 1–250
1. The mountain pine beetle (Dendroctonus ponderosae) primarily attacks which pine species in
California?
A) Sugar pine
B) Ponderosa pine
C) Jeffery pine
D) All of the above
Answer: D
Rationale: Mountain pine beetle attacks many pine species, including ponderosa, sugar, and Jeffery
pine, especially during drought and overcrowding.
, Page 3 of 149
2. Under California law, a pesticide use report for a forest pest control application must be submitted to
the county agricultural commissioner within how many days?
A) 10 days
B) 30 days
C) 60 days
D) 90 days
Answer: B
Rationale: California requires pesticide use reports to be filed within 30 days of application.
3. The sudden oak death pathogen (Phytophthora ramorum) primarily causes:
A) Root rot in conifers
B) Bark cankers and mortality in tanoak and coast live oak
C) Defoliation of hardwoods
D) Needle blight in pines
, Page 4 of 149
Answer: B
Rationale: Phytophthora ramorum causes lethal cankers on tanoak and several oak species; it is a major
forest disease in coastal California.
4. A forest pest control applicator applies an insecticide near a known spotted owl nesting site. The
applicator must:
A) Notify the California Department of Fish and Wildlife (CDFW)
B) Consult the US Fish & Wildlife Service under the Endangered Species Act
C) Apply only at night
D) Use only ground application
Answer: B
Rationale: Spotted owl is listed under the Endangered Species Act; consultation with USFWS may be
required.
