PESTICIDE APPLIANCES

1. Manually operated 2. Power operated(physical action of the (engine or battery)operator)

mona

APPLIANCES OF PESTICIDES CAN BE DONE BY USING :- A. DUSTERS B.SPRAYERS

Mona

DUSTERS: Duster is a machine to apply chemical in dust form. Dusters make use of air streams to carry pesticides in finely divided form on the plants.Dusters essentially consists of 5 parts a. Hopper b. Agitatorc. Feed control d. Fan or blower ande. Delivery nozzle

TYPES OF DUSTERS

1. MANUALLY OPERATED 2. POWER OPERATED

a. Plunger duster a. Power dusterb. Bellows duster b. Power take off dusterc. Rotary duster c. Traction duster d. Wet duster

mona

1.MANUALLY OPERATEDA. Plunger duster :These consists of a air pump of the simple plunger type, a dust chamber. These are useful for spot application in restriction areas and for controlling ants, poultry pests and pest of farm animals.

Mona

B. BELLOWS DUSTER: On squezzing it pufs the air that expels the dust in a small cloud. These are also used for spot teatment. Capacity 2.5kg-5.0kg.

mona

C. Rotatory dusters: It consists basically of a blower complete with a gear box and a hopper. It can be carried in hand, shoulder mounted and belley carried type.

mona

2.POWER OPERATEDA. POWER DUSTER : It resembles the rotatory duster except the power to drive the blower through the gear box. Power dusters are manufactured in varieties of forms.

MONA

B.POWER TAKE OFF DUSTER: They have a auxiliary engine. They have only one big metal hose which can be turned to direct dust in any direction. Airplane dusters have been successfully used to apply dust to both field crops and orchards.

mona

C.TRACTION DUSTER: Traction dusters derive their power from the turning of the land wheels. There are two types of traction dusters wheel barrow type and two wheeled trailer type. Wheel barrow type are used foe small areas and the other is for large area or field.

mona

SPRAYERS: Sprayer is a machine to apply fluids in the form of droplets. It helps to break the liquids into droplets for effective size for uniform application over the plants.

mona

COMPONENTS OF SPRAYERThere are 15 components or parts of sprayers1. Nozzle body 2. Swrill plate 3.Filter 4. Over flow pipe 5. Releif valve 6. Pressure regulator 7. Cut-off valve8. Spray boom 9. drop legs10.Nozzle boss 11. Nozzle disc12.Nozzle cap 13.Nozzle tip14.Spray lance 15.Spray Gun

TYPES OF SPRAYERS

1.MANUALLY OPERATED 2.POWER OPERATED

a. HAND SYRINGE a. STRETCHER SPRAYER b.HAND SPRAYER b.POWER TAKE OFF SPRAYER c. KNAPSACK SPRAYER c. TRACTION SPRAYER d. BUCKET SPRAYER d. MIST BLOWER AND SPRAYER e. ROCKER SPRAYER e. ULTRA LOW VOLUME SPRAYER f. FOOT SPRAYER OR PEDAL PUMP

mona

MANUALLY OPERATEDa . HAND SYRINGE: The hand syringe is a small, light and compact unit. This is generally used for spraying small.

MONA

B. HAND SPRAYER: The hand sprayer is a small, light and compact unit.The capacity of the container varies from 500 to 1000 ml. This is generally used for spraying small areas like kitchen garden and experimental laboratory plots . It is a hydraulic energy sprayer.

C.KNAPSACK SPRAYER: Any sprayer which is carried on the back of the operator is called a knapsack sprayer.The commonly used manually operated knapsack sprayer will have one hydraulic pump working inside the container.

MONA

4. ROCKER SPRAYER: The rocking sprayer has a pump assembly, fixed on a wooden platform with an operating lever, a valve assembly with two ball valves, a pressure chamber, suction hose with strainer, and delivery hose with spray lance.

MONA

5.BUCKET SPRAYER: The bucket sprayer is designed to pump the spray fluid directly from, the open container, usually a bucket.The hydraulic pump will be put inside the bucked and held properly with the help of foot rest.

MONA

OTHER APPLIANCESSoil injector: For applying liquid formulations.Granule applicator: For applying granule formulations.Bird scarer : For driving away birdsFrame thrower: For producing flames.Seed dressing machine: For coating seeds with chemicals.Slurry seed treatment machine: For preparing a slurry.
