2.11.1 Manually Operated Sprayer
This
is a type of sprayer that is manually carried by the operator and
operated by human power using hand or feet to activate the pump. This
include backpack sprayer (Knapsack sprayer) e.t.c.
Back pack sprayer/Knapsack sprayer
Widely
used in agriculture, this is carried on the back. A frame or shield
prevents contact between the tank and the back. It is a continuous type
of sprayer with a fairly constant discharge rate. The person maintains
pressure in the tank by pumping air with a lever with one hand and ducks
the spray lane with the other. If the sprayer is filled with a spray
control value, continuous pumping may not be necessary. The knapsack
sprayer can be used for spraying breeding sites with larvicides but
should not be used for resided wall-spraying.
ii. Stirrup Pump Sprayer
There
are used in some vector control programmes because they are less costly
than compression sprayers. The pump, mounted on a foot rest or stirrup,
is inserted in the spray liquid in a bucket. A here attached to the
pump leads to the spray lance. Two persons are needed, one to pump and
one to direct the spray. The pressure varies with the speed of pumping,
and so it is difficult to make uniform spray applications. Because of
their in a accuracy and because of the risk of spilling insecticide from
the open bucket inside houses, stirrup pumps are not recommended. They
should not be used with hazardous pesticides.
2.11.2 Components Parts of Sprayers
The basic essential components of sprayers are:-
The tank
Pump
Fitter/strainer
Boom
Nozzles
Pressure gauge
Control value
Adjustable relief value
Disturbing systems
Pressure regulators

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Background to the study Sprayers are devices that are specially designed to spray liquid quickly and easily. They come in a number of different varieties. A sprayer is used to cover large area such as lawns quickly and easily. A boom sprayer of this type is typically used for spraying chemicals such as pesticides, herbicides, herbicides, insecticides and fungicides.Along with proper plant selection and cure, controlling pests in lawn or garden is an important par ...

CHAPTER THREE - [ Total Page(s): 2 ]PRESSURE CONTROL VALVE(REGULATOR); This is a device or mechanism that
maintain any pre-set pressure by by-passing some of the liquid back to
the tank i.e it serves as safety device in automatically unloading the
excessive pressure. (It is a means of adjusting the pressure as required
for the job).PRESSURE GUAGE; This is a component pant of the
sprayer that always indicate the actual pressure at which the sprayer is
working. If properly calibrated, it provides guide to the operator in ... Continue reading---
