2.9 Crop Protection Equipment
Crop
protection equipments can be refer to as devices which are designed for
purposes of preventing planted crops from destructive agents such as
weeds, diseases, insect, pest e.t.c. on a farmland or harvested crops in
stored areas.
The chief crop protection operations are the
application of herbicides to educe the competition from weeds,
protective fungicides ‘to minimize the effects of fungus diseases;
insecticides to control various kinds of insect pests and hormones to
regulate crop growth. In addition, spraying is employed for the
application of micro-nutrients such as managers or boron, for burning of
excessive flag on cereal crops in order to reduce the changer of
lodging.
2.10 Classification of Crop Protection Equipment
Crop protection equipment can majorly be classified into two
Sprayer
Dusters
2.10.1 Dusters
A
duster can either be normally operated on powered. The power may be
shoulder mounted or belly mounted while it is operated the prevailing
wind donation should be used to carry out the dust to the target.
Dusters are of different types e.g Air planer duster e.t.c.
A duster companies of some components which include.
A hopper for storing the chemical in dust form
An agitator which is usually provided within the hopper to keep the dust moving freely and prevent it caking
A metering machine which is mostly an adjustable orifice that allows the discharge rate to be varied e.t.c.
2.10.2 Sprayers
A
sprayer is a machine or device designed and make for application of
liquid chemicals (e.g insecticides, pesticides, fertilizers e.t.c.) in
fire and smooth spray.
The spray materials can be in the form of the following
Solution: The homogeneous mixture of two or more substances of similar
molecular structure. Water is a common solvent, also oil.
Suspension: Two phase system consisting of very small solid particle
distributed in liquid dispersion medium. The active material is present
in solid particles dispersed in oil or water.
Emulsion: Solid particles solved in organic solvent capable of further dilute in water. Requirement of emulsion include
Sufficient stability after dillusion
High oil content but suitable for measuring and mixing
Not corrosive to strange container
2.11 Classification of Sprayer
Sprayer is being classified into based on the following:
Method of droplet
Hydraulic (liquid) Energy Sprayer
Gasoline Energy Sprayer
Centrifugal Energy Sprayer
Kinetic Energy Sprayer
Thermal Energy Sprayer
According to source of power
Manually Operated e.g Knapsack Sprayers
Power Operated – Auxiliary engine, hydraulic motor PTO of tractor and electric motor e.g (Boom Sprayer)
Mode of carrying
Hand held
Knapsack (back carry)
Front carry
Shoulder shay
Barrow
Trailed tractor
Self propelled
Vehicle
Air craft mounted
Volumetric Capacity
Ultral-low volume (U-ULV) – Less Il/ha
Ultral-low volume (ULV) – 1- 5 L/ha
Low volume (LV) – 5-50 L/ha
Medium Volume (MV) 50 – 250 L/ha
High volume (HV) – 250 L/ha
Purpose of utilization
Crop sprayer
Orchad sprayer
Garden sprayer
System of delivery
Hydraulic
Hydro preumatic
Blower sprayer (air carried system)
Acrosol generator

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---
