Colorado QS/CO Pesticide Test EXAM 2025 COMPLETE EXAM QUESTIONS AND
ACCURATE ANSWERS |ALREADY PASSED!!
2 categories of certified operators - ✔✔Private Applicators
Commercial Applicators
4 types of pesticide registration - ✔✔Section 3 - full federal label
Section 18 - emergency exemptions
Section 24c - special local needs label
Section 25b - minimum risk pesticides
Actions to take to minimize pesticide impact on pollinators -
✔✔Follow the label each year
Communicate and coordinate applications with beekeepers
Avoid treating plants when they are in bloom
Treat plants during times when pollinators are not active
Avoid drift onto flowering plants and pollinator areas
Control noxious weeds in fields or orchards that may attract
pollinators
Advantages to aerosol generator or fogger sprayers - ✔✔Fine droplets
can penetrate tiny cracks, crevices, and heavy vegetation to reach
pests in hard-to-reach areas
,Advantages to airblast sprayers - ✔✔Small amount of water covers
large area
Little operating time lost in refilling
Adapted to applying sprays over large area
Advantages to chemigation - ✔✔Low cost of application
Provides thorough crop coverage
Advantages to duster sprayers - ✔✔Lightweight, relatively cheap, and
fast acting
Do not require water
Advantages to granular applicators - ✔✔Equipment is light, relatively
simple, and does not involve the use of water or other diluents
Heavy particles reduce drift and allow precise placement and
penetration
Advantages to hand sprayers - ✔✔Economical, uncomplicated,
lightweight, and adaptable to many different situations
Ideal for spot treatments
Advantages to high pressure hydraulic sprayers - ✔✔Have enough
pressure for spray to penetrate heavy brush, livestock hair, and tops
of tall trees
,Trees or other hard-to-reach places can be treated with a long hose or
handgun
Advantages to low pressure hydraulic sprayers - ✔✔Relatively
inexpensive, lightweight, and adapted to many uses
Can cover large areas rapidly
Usually low volume so one tankful will cover large area
Advantages to mist blower sprayers - ✔✔Saves time and labor
because less water is handled than with airblast sprayers
Advantages to soil injectors - ✔✔Minimal drift
Some soil systemic insecticides can give more persistent control than
foliar treatments
Advantages to ULV sprayers - ✔✔Saves time and labor due to the
elimination of water use
Aerosol generator or fogger sprayers - ✔✔These break certain
pesticide formulations into very small, fine droplets
Used to fill an area like a greenhouse or to control flies and mosquitos
Aesthetic threshold - ✔✔When the appearance of the damage caused
by the pest is too much so action is needed
, These are difficult to develop as this is very subjective
Aggregate Pesticide Exposure - ✔✔All possible sources of exposure to
the same pesticide
Agricultural Chemicals and Groundwater Protection Act - ✔✔Imposed
rules for mixing and loading areas for pesticides, when they are
handled in quantities that exceed minimum thresholds.
A mixing and loading pad is required if you mix and load more than
500 gallons of liquid formulated product, 3000 lbs of dry formulated
product, or 1500 lbs of active ingredient of a combination of liquid
and dry product at one site annually.
Airblast sprayer calibration - tank level method - ✔✔1. Select and
measure a calibration plot size in the .1-1 acre range
2. Fill tank full or to some other known level with water only
3. Spray only the calibration plot previously selected and measured
4. Return to the filling site and accurately measure the amount of
water needed to refill the tank to the previous level.
5. Determine the rate by dividing the gallons of water by the area
sprayed
Airblast sprayers - ✔✔Designed to carry pesticide and water mixtures
under pressure from a pump through a series of nozzles into a blast of
air that blows into a tree by means of a fan
