the Allegheny Mountain districts, satisfactory results may 

 be had from two applications, namely, the first with self- 

 boiled lime-sulfur and arsenate of lead four to five weeks 

 after the petals fall, and the second treatment of the above 

 schedule with self-boiled lime-sulfur alone three to four weeks 

 later. These two treatments, if thoroughly applied, will 

 control the scab and brown-rot, especially on the early 

 and midseason varieties, and will materially reduce cur- 

 culio injuries. Even one application of the combined spray 

 made about five weeks after the petals fall would pay well, 

 although this is recommended only for conditions where 

 it is not feasible to do more." 



Spraying equipment. 



It is unnecessary in this connection to consider spraying 

 equipment at any length. The peach-grower with spray- 

 ing to do has only two alternatives in the choice of equip- 

 ment so far as type of apparatus is concerned. If his orchard 

 is small, he can get along with a hand barrel-pump. If 

 more extensive, a power-sprayer is a practical necessity. 

 Where the dividing line between the two types of equip- 

 ment falls, as expressed in acres or in economy of operation, 

 cannot be stated arbitrarily. The relative cost, availability 

 of labor, and other local factors all enter into the considera- 

 tion. 



If a hand pump is used, a single "lead" of hose only will 

 be required, but with a power sprayer at least two lines are 

 generally used. In either case the lines of hose should be 25 

 to 35 feet in length and an extension rod 6 or 8 feet long or a 

 spray-gun will usually be advantageous; also nozzles that 

 will throw a very fine spray. While trees that are pruned to 

 low heads can usually be reached fairly well from the ground
