Which of the following
could be a result
of proper equipment calibration?

Better spray coverage
during high winds

Unnecessary loss of time and money

Inadequate pest control

Effective pest control

Why must you
accurately measure the
capacity of your
spray tank?

When making a
pesticide application,
increasing travel speed
of the spraying equipment will :

If sprayer output is
not changed,
what will you
need to do to
the travel speed
of the application
equipment to
maintain the same
rate per acre when
the swath width
narrows from 20 to
15 feet?

.

For calibration,
which four factors
need to be measured?

Travel speed, sprayer pressure,
number of nozzles,
and nozzle height

Swath width, size of area
to be treated, travel speed,
and sprayer pressure

Tank capacity, travel speed,
swath width, and
sprayer output (flow rate)

Nozzle height, size of area
to be treated, travel speed,
and swath width

To double the
output volume of
a sprayer by
increasing pressure,
you must adjust
the pressure regulator
to increase the
pressure by a factor of :
