CO PESTICIDE APPLICATORS TEST: INDUSTRIAL RIGHT OF
WAY EXAM QUESTIONS AND ANSWERS WIT COMPLETE
SOLUTIONS VERIFIED
Dry Flowable (DF)
Formulation made of finely ground herbicide particles, compressed into granules that can be suspended
readily in water for application
Disposal
Process of discarding or throwing away unused spray material, surplus pesticides, and pesticide
containers
Abiotic Factors
Nonliving components of environment.
Absorption
Process in which herbicides are taken into plants, by roots or foliage. Also the movement of chemical
into plants, animals, and microorganisms
Acid Equivalent (ae)
Amount of herbicide in a formulation when measured in its acid form that is principally responsible for
the herbicidal effects and that is shown in the active ingredient statement on the herbicide labels
,Active Ingredient (ai)
Chemical(s) in a formulated product that is (are) principally responsible for the herbicidal effects and
that is (are) shown as active ingredient(s) on herbicide labels
Acute Poisoning
Poisoning which occurs when a large amount of pesticides enters the body. Adverse effects resulting
from a single exposure are seen quickly
Adjuvant
Any substance in a herbicide formulation or added to the spray solution that enhances the herbicides
effectiveness
Adsorption
Process by which an ion (or charged particle) in a solution bonds to a charged surface
Agitation
To keep pesticide chemical mixed up. to keep it from separating or settling in the spray tank
Agitator
A paddle, air, or hydraulic action to keep a pesticide chemical mixed in the spray or loading tank.
Air Blast Sprayer
Machine which applies pesticides using air and using low liquid volumes
Allelopathy
Inhibition of growth of one plant species by another due to the release of chemical substances
,Amine
Acid or anionic herbicides that can be formulated as ammonium salts or amines
Amino Acid Synthesis Inhibitors
Herbicide mode of action that inhibits amino acid synthesis which is necessary for the formulation of
plant proteins
Annual
Plant that completes its life cycle within one year and then dies
Antidote
Treatment used to counteract the effects of pesticide poisoning or some other poison in the body
Application rate
Amount of pesticide applied to a site, usually expressed as a liquid or dry measure per unit area
Aryloxyphenoxypropionates
Chemical family of herbicides whose mode of action is lipid inhibition
Backflow
Reverse flow condition, created by a difference in water pressures, which causes water to flow back into
the distribution pipes of a potable water supply from any source or sources other than an intended
source
Backsiphonage
Form of backflow caused by a negative or below atmospheric process within a water system
, Backpack Sprayer
Sprayer that can be strapped on the back and used to apply liquid pesticides. Attached hose has a nozzle
at the tip that can be aimed at the spot to be treated
Band Treatment
Treated strip extending from a few inches to a few inches to a few feet on each side of an object such as
a tree or plant
Bareground Treatment
Long-term residual herbicide that kills plant life
Basal
Produced at ground level
Basal Treatment
Applied to encircle the stem of a plant aboveground and at the ground such that a foliage contact is
minimal, mainly used on woody plants
Benzoic Acids
Chemical family of herbicides whose mode of action is as a growth regulator
Biennial
Plant that completes its growth in two years. First year it produces leaves and stores food; the second
year it produces flowers and seeds
Biological Control
