DPR - NON SOIL FUMIGATION
EXAM QUESTIONS AND
ANSWERS 2026 - 2027
A contact pesticide which has a localized pesticidal affect; not
transported through the plant or animal tissues - ANSWERS-Non-
systemic
An undesirable discharge of sanitary or combined sewer flow into a
river, scream, or other surface water. - ANSWERS-Overflow
NOT the same as vapor or gas. Microscopic particles of solid or liquid
matter suspended in the air. - ANSWERS-Particulate
Stricter requirements than those on the pesticides labeling or in
California law and regulation. Permit conditions are issued by the
county agricultural commissioner and must be followed. -
ANSWERS-Permit conditions
This document describes any actions or events that occurred during
the fumigation that differed from the fumigation management plan,
measurements like humidity for example taken to comply with good
agricultural practices (GAPs), if not recorded in the FMP, the national
weather service forecast during application 48 hours following
application, and any incidents or complaints - ANSWERS-Post
application summary
,Any pesticide that, for a reasonable length of time, is effective in
preventing the development and activity of wood rotting fungi, bars of
various kinds, and harmful insects that deteriorate wood. -
ANSWERS-Preservative
A method of vacuum chamber fumigation where the pressure is
lowered, fumigant introduced and then pressure is restored. This is
called "below NAP " (normal atmospheric pressure). - ANSWERS-
Restored pressure fumigation
A permit issued by the county agricultural commissioner to authorize
certified applicators to purchase, possess, and use California restricted
materials - ANSWERS-Restricted materials permit
A sewer designed to carry only residential or commercial waste, as
opposed to a storm sewer. - ANSWERS-Sanitary sewer
The soft outer layers of recently formed wood between the heartwood
and the bark, containing the functioning vascular tissue. -
ANSWERS-Sapwood
A type of decay developing under very wet conditions (as in cooling
towers in boat timbers) in the outer wood layers. It is caused by
cellulose destroying micro fungi that attacked the secondary cell walls
but not the intercellular layer. - ANSWERS-Soft rot
, The ability of a substance to dissolve in another substance (e.g., salt in
water) - ANSWERS-Solubility
A physical and chemical process by which one substance becomes
attached to another. The term covers both absorption and adsorption -
ANSWERS-Sorption
The ratio of the density of any substance to the density of some other
substance taken as standard, water being the standard for liquids and
solids, and hydrogen or air being the standard for gases. -
ANSWERS-Specific gravity
A reproductive structure produced by some plants and micro
organisms that is resistant to environmental influences. - ANSWERS-
Spores
The process of sealing a building in applying a fumigant to control
pests - ANSWERS-Structural fumigation
An adjuvant used to improve the ability of the pesticides to stick to
and be absorbed by the target surface - ANSWERS-Surfactant
A method of vacuum chamber fumigation where pressure inside the
chamber is reduced, fumigant is introduced, and the lower pressure is
maintained throughout the fumigation. - ANSWERS-Sustained-
