New Hampshire Commercial Applicator Certification –
Category G2 Ornamental Pest Control Exam COMPLETE
QUESTIONS AND DETAILED SOLUTIONS LATEST UPDATE
THIS YEAR-JUST RELEASED
New Hampshire Commercial Applicator Certification – Category G2: Ornamental Pest Control
Exam Coverage (Summarized Point Form)
I. Regulatory & Legal Framework
• NH RSA Chapter 430 – Insect Pests and Plant Diseases; establishes the Pesticide Control Board’s
authority, pesticide sale/use restrictions, and dealer licensing
• NH Code of Administrative Rules (Agr 3800; Pes 100–1100) – Official regulations governing
pesticide control, applicator certification, restricted-use pesticide daily recordkeeping, and
water resource protection
• FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) – Federal pesticide registration and
labeling requirements
• License Types – Supervisory Registration Certificate – General Use (categories B, C1, F2 for 25b,
F8, G1, G2); at least one supervisor per firm
• Operational License – Required for at least one crew member applying pesticides commercially
• Examination Structure – Written exams for each category (general, regulations, category), with
true-false, completion, multiple-choice, and problem-type questions
II. Core Pest Control Principles
• Integrated Pest Management (IPM) – pest identification, monitoring, economic thresholds,
cultural/mechanical/biological/chemical controls
• Worker Protection Standard (WPS) – pesticide safety training, restricted-entry intervals (REI),
decontamination supplies, emergency medical information
• Pesticide Label Comprehension – Signal words (Caution, Warning, Danger), active ingredients,
EPA registration number, re-entry intervals, use restrictions, storage/disposal
• Hazard Communication – Routes of exposure (dermal, inhalation, oral), personal protective
equipment (PPE) selection, heat stress, pesticide poisoning symptoms
III. Ornamental Pest Identification & Diagnosis
• Insects – Japanese beetle, Asiatic garden beetle, rose chafer, viburnum leaf beetle, azalea lace
bug, boxwood leafminer, hemlock woolly adelgid, aphids (red aphids on sunflowers, honeydew
production), scale insects, four-lined plant bug, hornworms, white grubs, Asian longhorned
beetle
• Diseases – fungal leaf spots, powdery mildew, blights, rusts, root rots, bacterial leaf scorch
• Weeds – broadleaf weeds (prostrate spurge, white clover), grassy weeds (crabgrass,
goosegrass), sedges (yellow nutsedge)
• Plant Health – diagnosing abiotic disorders (drought, nutrient deficiency, herbicide
phytotoxicity, salt damage)
IV. Application Equipment & Calibration
• Low-Pressure Sprayers – hand-held compression sprayers, backpack sprayers, hose-end
sprayers
• Hydraulic Sprayers – tank, pump, agitation, pressure regulator, nozzles (flat-fan, cone,
adjustable)
• Granular Applicators – drop spreaders, rotary (spinning disc) spreaders
, Page 2 of 133
• Calibration – determining GPA or lbs/1,000 sq ft; collecting nozzle output; adjusting pressure,
speed, or nozzle size to achieve desired rate
• Calibration Calculations – Gallons Per Acre (GPA) = (Gallons Collected x 5940) ÷ (Nozzle Spacing
(in) x Distance (ft)); Application Rate (lbs/1,000 sq ft) = (Amount Collected (oz) ÷ 128) ÷ 0.23
V. Pesticides & Formulations
• Insecticides – organophosphates (malathion), carbamates (carbaryl), pyrethroids (bifenthrin,
permethrin), neonicotinoids (imidacloprid), insect growth regulators (IGRs), microbials (Bacillus
thuringiensis – Bt)
• Fungicides – protectants (mancozeb, chlorothalonil), systemic fungicides (propiconazole,
myclobutanil, trifloxystrobin)
• Herbicides – pre-emergence (pendimethalin, prodiamine), post-emergence (glyphosate, 2,4-D,
dicamba), selective (triclopyr)
• Adjuvants – surfactants, spreader-stickers, crop oils, drift control agents
• Soil Fumigants – methyl bromide, metam sodium (restricted-use)
VI. Safety, Environmental Protection & Recordkeeping
• Personal Protective Equipment (PPE) – chemical-resistant gloves, coveralls, goggles/face shield,
respirator, head/body protection
• Decontamination – triple-rinsing containers, washing PPE, cleaning equipment, reducing
exposure
• Drift Prevention – nozzle selection (low-drift), wind speed/direction monitoring, buffer zones
• Protecting Water Resources – wells, surface water, groundwater; avoiding back-siphoning,
installing check valves
• Storage & Disposal – locked cabinets, secondary containment, disposal of containers per NH
regulations
• Recordkeeping – pest(s) targeted, pesticide name and EPA number, amount applied, location,
date, applicator signature; keep 3 years
• New Hampshire Division of Pesticide Control – (603) 271-3550 for registration status, license
verification, rule enforcement
VII. Special Situations & Regulatory Updates
• Restricted-Use Pesticides – require Daily Use Recordkeeping under Pes 900; added training for
purchase/use
• Pesticide Dealer Licensing – each location selling restricted-use pesticides requires a license
• Aquatic Application of Pesticides – Pes 600 series: requirements for near-water applications
• Invasive Species Regulations (Agr 3800) – covers detection, reporting, and management of
invasive pests
• Annual Use Report – required for Private Applicator – General Use Permit (no exam)
250 Scenario-Based Practice Questions (Random Order)
Each question includes an answer and a concise rationale based on the exam coverage above.

1. A commercial applicator is applying an over-the-counter homeowner-type insecticide to a client’s
azaleas. Under New Hampshire law, is a license required?
A) No, because the product is sold over the counter.
B) Yes, any commercial application on another’s property requires licensing.
C) No, if the product is labeled “organic” or “natural.”
D) Yes, but only if the applicator is paid for the service.
Answer: B – NH law requires commercial applicator licensing regardless of whether the pesticide is
general use, over-the-counter, organic, or natural. The determining factor is applying pesticides on
another’s property for any form of compensation.
2. Which of the following is an official New Hampshire regulation covering invasive species
management?
A) Pes 100–1100
B) Agr 3800
C) RSA 430:60
D) FIFRA Section 25(b)
Answer: B – Agr 3800 is the New Hampshire Administrative Rule covering invasive species.

3. A technician is applying a restricted-use insecticide to ornamental shrubs on a commercial property.
What additional recordkeeping requirement applies under Pes 900?
A) No extra records are needed.
B) Daily Use Recordkeeping with transaction details per Pes 300.
C) Only the product name and date are required.
D) A separate permit must be obtained for each shrub.
Answer: B – Restricted-use pesticides require Daily Use Recordkeeping under Pes 900, with new
information to be recorded per transaction under Pes 300.
4. A homeowner notices sticky, shiny deposits on the leaves of her oak tree. The most likely cause is:
A) Bacterial leaf scorch
B) Honeydew from aphids or other sap-feeding insects
C) Powdery mildew
D) Herbicide drift from a nearby lawn
Answer: B – Aphids and other sap-feeding pests excrete honeydew, which creates a sticky sheen on
leaves. This honeydew can also cause sooty mold.
