EQUIPMENT FOR SPRAYING. 



Much dissatisfaction in spray- 

 ing for the control of pests on 

 citrus trees arises from the use 

 of inefficient equipment. The 

 equipment for spraying should 

 be adapted to the particular 

 needs of the grower and also to 

 the size of the trees and the na- 

 ture of the grove to be sprayed.

Barrel pump. A barrel pump 

 (fig. 10), which -will supply one 

 lead of hose, will serve every purpose if the trees are low and 

 only a small amount of spraying is required, and will save invest-

 chine until such time 

 as the work necessi- 

 tates one. For three 

 years or longer after 

 planting this pump 

 will answer the pur- 

 pose very satisfac- 

 torily. In fact, one

 who sprays, has used 

 a barrel pump for 

 three years in his 

 grove of 800 trees

 pump, indeed, is a 

 necessity in any 

 grove where insects 

 are controlled by 

 spraying. Many
