SPRAYING AND DUSTING EQUIPMENT 



Many types of sprayers, dusters, and accessories are obtainable for 

 use in applying insecticides. These range in size from those suitable 

 for the home gardener to those adapted for the large commercial 

 grower. Certain commonly used types are discussed below. 



Sprayers 



Hand atomizers. — These are the familiar sprayers (fig. 1) used for 

 applying fly sprays in the home. Usually they hold from a half pint 

 to a quart or more of material. They are useful for spraying house 

 plants or very small outdoor plantings and are generally available 

 locally.
