THE APPLICATION OF INSECTICIDES. Within the past 

 few years, great progress has been made in the development 

 of pumps, nozzles and other appliances for spraying plants, 

 and there are also many devices for the dry application of 

 insecticides. 



Spraying apparatus ranges from elaborate power 

 outfits to portable sprayers carried by one man, and 

 syringes, atomizers and similar simple machines for the 

 treatment of house and garden plants.
