I ment midway between the 3rd and 4th applications is sometimes necessary
 Note: In the more northern apple growing sections the first four appli- cations will, during ordinary seasons be sufficient to protect the fruit from various insects and diseases mention ed. In the more central states, where bitter-rot and blotch are prevalent the fifth and sixth applications will be necessary. In the case of summer apples, only theflrst three applications arc necessary.
 Peach Spraying.
 There are four or five serious in sect and fungous pests of the peach effectively controlled by spraying Notwithstanding the fact that the lar ger commercial growers throughout the country have adopted measures fol the control of these troubles, there is still room for such improvement or the part of many orchardists espec- ially those having small home or chards. Although successful spray ing of the apple has been practiceo for many years, it is only recently thai sprays have been developed which are effective and safe for the tender fo. liage and fruit of the peach and cer. tain other stone fruits. The develop ment of the combination spray of ar senate of lead and the self-boiled lime sulphur mixture has been of enor- nous value to peach growers, and its use has placed the cultivation of this crop on a much sounder basis thar heretofore.
 Insect Pests.
 The Plum Curculio: This insect already referred to under the head of apple, is the cause of a large amount of injury to the peach. Aside from the injury which it actually does to the fruit, it's attack much favors the spread and infection of the frui1 by brown-rot fungus. Its control i: therefore especially essential in con nection with remedial operation: against brown-rot.
 The San Jose Scale: This insect also mentioned under apple insects requires treatment on the peach Applications should be made while the trees are dormant, and if spray ing be delayed to just before the budi are due to swell, the treatment alst controls peach leaf curl. Wintel strength commercial lime-sulphur SO lution is almost universally used il the case of the peach, since the frui buds and twigs are more likely to b. injured by oil sprays than is true O the pome fruits.
 Diseases.
 Leaf Curl: This disease affects tn, leaves of the peach, causing, them t. become reddened and curled. It begin quite early in the season and is easil, controlled by the same treatmen which controls scale insects. Peach Scab: This disease is tn ordinary black spot of freckles of tn peach. It appears early in the sum mer and when several spots run to gether and infections are numerous 1t gives the fruit smutty appearance Severely infected fruits are dwarfe, or misshapen, and are often cracke' so severely as to cause dropping. Thi disease causes more loss to grower than is ordinarily realized becaue in their normal size.
 
 rot of the peach which is so oftel very destructive at ripening time, an Is the only peach rot of commercia importance It is particularly de structive during warm, moist weather Especially in the South it may some times cause the loss of practically tn entire crop.
 Schedule of Applications. In the eastern half of the Unite l States most of the peach orchard | should be given the combined treat | ment of arsenate of lead and self l boiled 1ime-sulphur mixture for cul i culio, scab and brown-rot. The cul culio and brown-rot are more espet ially troublesome in the South. where ] as peach scab is worst in the A1ls ghany Mountain region and in tt Northern States.
 Midseason varieties: The Mic season varieties of peaches, such { Reeves, Belle, Early Crawford, B berta, should be sprayed as follows: CD With two pounds of arsena of lead paste Cor one pound of arsel I ate of lead powdered) per 50 gallol , of water, to which has been addt the milk of lime made from slaki1 three or four pounds of stone linn about 10 days after the petals fall, , at the time the calyxes ar esheddin CD With self-boiled lime-sulphl
 mixture to weeks before the fru 1 is due to ripen.
 Late varieties: The Salway. Heat Bilyeu and other varieties with a sir l liar ripening period should receive U
 same treatment prescribed above, wi 7 an additional application of self-bo . l ed lime sulphur mixture alone to , applied or 4 weeks after the SC 5 ond application.
 Early varieties: The Greensbol |, Carman, Hiley, Mountain Rose, ct ' and varieties of the same ripening F E riod should receive the first and SC 3 ond applications only as prescr1b ]. | for mid-season varieties.
 Plum and Cherry Spraying.
 Japanese plums should receive t
 same treatment as peaches having t N same ripening season. Soap shot
 be added in the third application enable the spray to stick to the smoe plum fruits.
 Cherries should receive the sal ' treatment as early varieties of peac
 es except that commercial illness : phur solution diluted at the rate o1 |. gallon to 40 gallons of water sho' |. oe used in place of the self-boiled lin sulphur. Where leaf-spot has be e severe this solution should also
