INSECTICIDES, FUNGICIDES, AND SPRAYING 209 



As in the case of insecticides, there are ready-prepared 

 fungicides on the market. These preparations have been 

 steadily improved and are coming into general use. They 

 may cost more than the crude chemicals do when pre- 

 pared by the user; ibut they are more economical in the 

 long run, because of the saving of the cost of labor of 

 making them. 



SPRAYING APPARATUS 



There is now on the market machinery for spraying 

 the smallest bush or the tallest tree. There are atomizers, 

 bucket-pumps, barrel hand-pumps and power-sprayers. 

 What sprayer to get depends upon the work required. No 

 matter what capacity sprayer it is intended to purchase it 

 is always best to communicate with the state experiment 

 station for information and advice. During the last few 

 years rapid strides have been made in the manufacture of 

 spraying apparatus, and it pays to take the trouble to ascer- 

 tain what is the best on the market. 



Bucket-Pumps. — A moet serviceable and very cheap ap- 

 paratus for spraying fruit and medium sized shade-trees is a 

 bucket-pump shown in Plate 42, Fig. 4. When using this 

 sprayer, the insecticide should be mixed in a barrel or other 

 receptacle, and small quantities poured into the bucket from 

 which the mixture is pumped. 



Barrel Hand-Pumps.— More powerful than the bucket- 

 pumps are the barrel hand-pumps. These consist of a hand- 

 pump set in a barrel of fifty or sixty gallons capacity which 

 contains the insecticide. They can generally supply from 

 two to four leads of hose and give sufficient pressure to pro- 

 duce a very fine spray. A good hand-pump, mounted on a 

 barrel or tank, furnishes a good outfit for the orchardist and
