NEW HAMPSHIRE COMMERCIAL PESTICIDE APPLICATOR CATEGORY C1
EXAM
Forest Pest Control and Timber Treatment
Practice Examination — 200 Multiple-Choice Questions with Correct Answers and
Rationales
Exam Description
This comprehensive practice examination is designed for applicants preparing for the New
Hampshire Commercial Pesticide Applicator Category C1 — Forest Pest Control and
Timber Treatment examination. Category C1 applies to commercial applicators using or
supervising pesticide use in forests and forest nurseries, including applicable public and private
lands.
The examination emphasizes the competency areas identified in New Hampshire rules: forest
and forest-nursery types and associated pests; pest occurrence and population dynamics;
selective biotic agents and their pesticide vulnerabilities; environmental protection and non-
target effects; and factors affecting pesticide drift. It also incorporates label comprehension,
pesticide safety, application practices, and regulatory principles relevant to commercial
applicators.
Total questions: 200
Format: Multiple choice, four options (A–D)
Correct answers: One per question
Difficulty distribution: 60 basic recall, 100 application, 40 analysis/critical thinking

IDENTIFICATION
Questions 1–40
Question 1
Which characteristic most directly distinguishes a forest ecosystem from a single-crop planting?
A. Forests contain only woody plants
B. Forests contain interacting organisms and physical factors over a relatively large area
C. Forests never require pest management
D. Forests have uniform soil conditions
Correct answer: B
Rationale: A forest is an ecosystem composed of organisms interacting with one another and
with soil, water, climate, and other physical factors. The main distractor, A, is incorrect because
forests contain many nonwoody organisms and plants.
Question 2
What is the primary function of chlorophyll in green tree foliage?
A. Absorb nutrients from soil
B. Capture light energy for photosynthesis
C. Prevent all insect feeding
D. Transport water through xylem
Correct answer: B
Rationale: Chlorophyll absorbs light energy used during photosynthesis. Option D describes a
function associated with vascular tissues rather than chlorophyll.
Question 3
Which tissue primarily transports water and dissolved minerals upward from the roots?
A. Phloem
B. Cambium
C. Xylem
D. Epidermis
Correct answer: C
,Rationale: Xylem transports water and mineral nutrients from roots toward stems and foliage.
Phloem primarily transports photosynthetic products and other organic compounds.
Question 4
Which tissue primarily transports sugars produced by photosynthesis?
A. Phloem
B. Xylem
C. Cork
D. Epidermis
Correct answer: A
Rationale: Phloem distributes sugars and other organic compounds throughout the plant. Xylem
is primarily responsible for water and mineral transport.
Question 5
Why is accurate tree identification important before applying a pesticide?
A. Different tree species can differ in susceptibility to pesticides and pests
B. All tree species respond identically to pesticides
C. Tree identification determines only the color of the spray
D. Identification is required only after treatment
Correct answer: A
Rationale: Tree species can differ in susceptibility to both pests and pesticide injury. Assuming
all species respond identically can result in ineffective treatment or phytotoxicity.
Question 6
What is phytotoxicity?
A. Increased pest reproduction
B. Injury to plants caused by a pesticide or pesticide-related treatment
C. Movement of pesticides through groundwater only
D. Natural resistance of insects to pesticides
Correct answer: B
Rationale: Phytotoxicity refers to pesticide-related injury to plants. It can result from unsuitable
products, rates, environmental conditions, or application practices.
Question 7
Which forest component is most directly responsible for absorbing most water and mineral
nutrients?
, A. Roots
B. Flowers
C. Bark surface
D. Needles alone
Correct answer: A
Rationale: Roots, particularly fine roots and associated structures, are responsible for most water
and mineral uptake. Foliage can absorb some materials but is not the principal uptake system.
Question 8
Which condition generally increases stress on forest trees?
A. Adequate soil moisture
B. Prolonged drought
C. Appropriate nutrient availability
D. Favorable growing conditions
Correct answer: B
Rationale: Prolonged drought reduces water availability and can impair tree physiological
processes. Healthy moisture conditions generally reduce drought-related stress.
Question 9
Which group includes organisms that can cause infectious tree diseases?
A. Pathogens
B. Pollinators only
C. Herbivorous mammals only
D. Decomposing leaves only
Correct answer: A
Rationale: Pathogens such as fungi, bacteria, viruses, and certain other organisms can cause
infectious diseases. Herbivores and decomposers can affect trees but are not all pathogens.
Question 10
Which type of pest feeds directly on living plant tissue?
A. Herbivore
B. Decomposer
C. Pollinator
D. Predator
Correct answer: A
