FUMIGATION EXAM | QUESTIONS, CORRECT ANSWERS & RATIONALES
2026/2027
OVERVIEW
• Comprehensive study guide containing 200 expertly crafted multiple-choice
questions covering all critical domains of soil fumigation pesticide application in
New Hampshire
• Designed for structured exam preparation with detailed rationales to reinforce
regulatory knowledge, safety protocols, and technical application competencies
required for F4S certification
1. What is the primary purpose of soil fumigation in agricultural pest
management?
A) To enhance soil nutrient content and fertility levels
B) To eliminate soil-dwelling pests such as nematodes, insects, and pathogens
C) To improve soil water retention capacity
D) To increase organic matter decomposition rates
E) To adjust soil pH levels for specific crops
CORRECT ANSWER: B) To eliminate soil-dwelling pests such as nematodes,
insects, and pathogens
RATIONALE: Soil fumigation is specifically designed to control soil-inhabiting pests
including nematodes, wireworms, termites, and fungal pathogens. The fumigant
gas penetrates soil structure to reach pests that cannot be controlled by surface
,applications. While fumigation may indirectly affect other soil properties, pest
elimination is the primary objective.
2. Which of the following is NOT a common soil fumigant approved for use in
New Hampshire?
A) Methyl bromide
B) Chloropicrin
C) 1,3-Dichloropropene
D) Glyphosate
E) Metam-sodium
CORRECT ANSWER: D) Glyphosate
RATIONALE: Glyphosate is a non-selective herbicide used for weed control and is
not classified as a soil fumigant. Methyl bromide, chloropicrin, 1,3-dichloropropene,
and metam-sodium are recognized soil fumigants. Glyphosate works through foliar
absorption and translocation, not soil fumigation action.
3. What does the acronym EPA stand for?
A) Environmental Protection Agency
B) Emergency Prevention Administration
C) Environmental Pest Assessment
D) Ecological Protection Authority
E) Environmental Pesticide Authorization
CORRECT ANSWER: A) Environmental Protection Agency

least 18 years of age. This age requirement ensures legal responsibility and capacity
to understand the serious hazards associated with pesticide handling and
application.
6. Which category of pesticide applicator license is required to apply soil
fumigants in New Hampshire?
A) Category F2 - Fungicide Application
B) Category F4S - Soil Fumigation
C) Category F6 - Structural Fumigation
D) Category F1 - General Fumigation
E) Category F5 - Commodity Fumigation
CORRECT ANSWER: B) Category F4S - Soil Fumigation
RATIONALE: The F4S category is specifically designated for soil fumigation activities.
Different applicator categories address different fumigation types and application
scenarios. Soil fumigation requires the F4S license due to the unique hazards,
environmental considerations, and technical requirements of soil treatment.
7. How long is a commercial pesticide applicator license valid in New
Hampshire?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
E) 10 years
CORRECT ANSWER: C) 3 years
