Played a major role in the rapid advancement of agricultural production

Spraying should not be done when the prevailing wind is above?

Have a much greater drift hazard and lower deposition efficiency that sprays

These compound are of mineral origin

These are synthetic compounds

These are used alone or to supplement the action of insecticides, fungicides and herbicides.

Often added to spray solutions as stickers, stabilizers and conditioning agents

Its function is to break the liquid into droplets of effective size and distribute them uniformly over the surface to be protected.

Its function is to regulate the amount of insecticide to avoid excessive application that might prove harmful or wasteful

Is the all-important mechanism which breaks the spray liquid into the desired size of droplets for application to the surface to be sprayed

Types of spray pattern

The amount or volume of spray to be applied per unit area (li/ha) depends upon the?

Categories of portable manual sprayers:

This sprayer uses a pump to press the liquid chemical

This sprayer utilizes compressed air using an air pump to push out the liquid

A sprayer that is used for continuous spraying for a long time as long as there is plenty of compressed air.

A sprayer that is operated with either internal combustion engines or electric motors. They maybe operated by gasoline engines of suitable size or the sprayer may be operated by tractor power

Classification of Power Sprayers:

A type of power sprayer which the spray pressure is built up by the direct action of the pump on the liquid spray material

Essential parts of a typical hydraulic sprayer:

A part of hydraulic sprayer that is capable of developing the pressure in the range required or many spray jobs.

Required to protect the positive-acting pumps from damage when the discharge line is closed and for the convenience of the operator

Have been the standard of the spraying industry for many years because of their satisfactory performance in pumping almost any spray materials.

A type of pump which is commonly used in the output range of less than 2-8 gal/min and up to 400 lb/in2 or more

A type of pump which is used in the range of about 7-60 gpm and pressures up to about 1000 psi

A type of pump which have been introduced into the spraying field in recent years for use in the lower pressure range. Compact and lightweight, these pumps are commonly mounted on and powered by the tractor power-take-off shaft.

A type of pump which is classified as positive displacement and self-priming and are available in sizes up to about 20 gpm

A type of pump which have the same operating characteristics and range of use in spraying as the gear-type pumps.

A type of pump which is suitable for spraying at pressure up to about 100 psi. Adapted for direct mounting on the PTO of the tractor. They area relatively unaffected by abrasive-type spray materials.

A type of pump which are used extensively for sprayers. This type of pump can handle most type of spray materials. They have long life and have a wide range of discharge.

Supplied on many models of power sprayers because they are easier to clean of spray residues when changing spray materials.

It is provided on the discharge line of the pump to level out the pulsation of the pump, thereby providing a constant nozzle pressure

It is essential to permit using the full range of materials

It is the means of adjusting the pressure as required for any spray job within the pressure range of the pump. This also serve as a safety device in automatically unloading the excess pressure, directing the unused discharge flow from the pump back to the tank.

It is included in the suction line between the tank and the pump to remove foreign material which affect the operation of the check valve, pump, and nozzle

Are used to take care of the various types of spraying jobs.

Consist essentially of horizontal structure member on which the nozzles are properly spaced and mounted.

Consists of an assembly of one to five nozzles supported on a single bracket.

This type of sprayer has been developed to provide in one machine the versatility required to meet the many spraying needs of diversified farms. It has the necessary pressure range to be used for weed spraying or for spraying fruit trees or livestock

The sprayers are recommended for those spraying jobs which are just too large or too tedious for coverage using manual sprayers.

These sprayers are used by commercial growers of fruit or truck crops and are the product of many years of successful development by the manufacturers in cooperation with the growers.

These sprayers have been designed primarily to meet the specific requirements of low-volume field spraying.

Two different models of Low-pressure, Low-volume Sprayers

This consist of components which are mounted by the user on the tractor.

The sprayers in this class have the same performance characteristics and field use as the tractor-mounted units.

These sprayers had been developed as special purpose machines to spray those field and row crops which are too high for conventional power sprayers and tractors.

This sprayer has the same range of use as the low-pressure, low volume sprayers where the spray liquid is carried in a pressure tank and the spraying pressure is developed by means of an engine-powered air compressor.

Also known as concentrate or mist sprayers and have been developed to apply pesticides in concentrated form.

These machine disperse the spray material in the form of extremely fine droplets which remain airborne for a considerable period of time.

This equipment is employed for the temporary control of adult mosquitoes, flies and other similar insects.

This sprayer employed the use of an airplane to apply and distribute spray material.

Is used for spraying orchards and areas where fixed-wing airplanes have difficulty in maneuvering.

Types of dusting equipment:

Duster of this type are easily attached and detached from a tractor. They are suitable for small farms where only one tractor is used to perform all the field operations.

Are operated by an auxiliary engine. Have only one large flexible metal hose which can be turned to direct dust in any directions

A duster used to apply dust to both field crops and orchards. Can dust approximately 140 ha/hr.
