Ohio Commercial Pesticide Applicator Certification
Category 1 Aerial Pest Control Exam2026/2027
COMPLETE QUESTIONS AND DETAILED
SOLUTIONS/JUST RELEASED
Which of the following steps is NOT a part of the
calibration process?
a. Determining actual travel speed
b. Collecting nozzle discharge
c. Checking the pressure at the nozzle
d. Buying the right chemical - ANSWER-D. While buying
the right chemical is a necessity in doing a good job of
spraying, it is not part of the calibration process. All of the
,other steps listed are important components of calibrating
a sprayer
Other factors that may impact pesticide spray output
include:
a. Sprayer tank agitation
b. Worn nozzles
c. Brand of tractor used to pull the sprayer
d. a and b - ANSWER-D. Inadequate agitation may result
in pesticides settling out in the bottom of the tank. The
pesticide mix applied may then be less or more than the
desired concentration. Worn nozzles may also contribute
to incorrect amounts of pesticides being applied.
,Brass nozzles will generally wear better than stainless
steel or ceramic nozzles.
a. True
b. False - ANSWER-B. Nozzles made of brass wear faster
than nozzles made other materials such as stainless steel.
The important idea here is to check nozzle flow rate
regularly to detect excessive wear, sprayer line blockages
and determine the accuracy of the pressure gauges
Pressure gauges should be placed next to the pump.
a. True
b. False - ANSWER-B. Pressure gauges should be
located on or near the spray boom. The pressure at the
, nozzle is important to output, The pressure at the pump
may vary significantly from the pressure at the nozzle.
When not in use pesticides should be stored in such a
manner as to allow:
a. Easy access to anybody needing them
b. No ventilation to keep the fumes from getting outside
c. No lighting to minimize degradation of the material
d. None of the above - ANSWER-D. Pesticide storage
areas should be in safe areas that preclude the entry of
unauthorized persons. These areas should be well
ventilated and well lighted. Additionally, these areas may
need protection from weather extremes and should be
equipped with a shovel, absorbent materials, paper,
