PRIVATE APPLICATOR EXAM CA
QUESTIONS WITH VERIFIED ANSWERS
acute illness - ANSWER-an illness that becomes apparent soon after an exposure to a
pesticide occurs
acute onset - ANSWER-symptoms of pesticide- related injury appear soon after the
exposure incident
Adjuvant - ANSWER-a material added to a pesticide mixture to improve or alter the
deposition, toxic effects, mixing ability, persistence, or other qualities of the active
ingredient
air gap - ANSWER-A space between the filling hose and the liquid in the pesticide tank
which prevents back flow of pesticide liquids into the water source. The air gap should
be a minimum of two times the diameter of the filling hose or pipe.
airblast sprayer - ANSWER-a sprayer that uses a high powered fan to carry spray
droplets to targeted surfaces. Air blast sprayers are usually used on tall plants such as
trees or vines.
Application frequency restriction - ANSWER-a limitation on the number of times a
particular pesticide may be applied to the same crop in a growing season.
Application Pattern - ANSWER-The course the applicator follows through the area being
treated with a pesticide
Aquifer - ANSWER-An underground formation of sand, gravel, or porous rock that
contains water. The place where groundwater is found.
Back Siphoning - ANSWER-the process that permits pesticide- contaminated water to
be sucked from a spray tank back into a well or other water source. Back siphoning is
prevented by providing an air gap or double check valve (back flow prevention device)
in the pipe or hose used to fill a spray tank
belly grinder - ANSWER-a hand operated device used to apply pesticide granules. The
device straps to the front of the operator, who then turns a crank while walking forward
through the treatment area.
Biological Control - ANSWER-the action of parasites, predators, pathogens, or
competitors in maintaining another organisms density at a lower average than would
occur in their absence. Biological controls may occur naturally in the field or be the
result of manipulation or introduction of biological control agents by people.
