SPRAYING OF APPLES REDUCED TO SIMPLEST TERMS. 



There are a good many growers wlio would like to get good fruit and 

 would be willing to go to some expense to get it, but who simply will 

 not bother to change from one material to another, to memorize a lot 

 of formulas, and vary the strengths of the mixtures. These persons 

 want to know of some one spraying treatment which they can adopt 

 with reasonable success, and they are willing to take slightly poorer 

 results if by so doing they can bring the matter down to a basis of easy 

 simplicity. 



For all such persons we recommend the Commercial Lime-sulphur 

 at 1 1-2 gallons to 50 gallons water, with 3 pounds of Arsenate of Lead. 

 (See page 29.) 



If this material be used for all spraying treatments, winter and sum- 

 mer, it will come as near giving satisfaction as any one material. It is 

 not necessary to use the arsenate of lead in winter applications, but 

 only when there is fruit or foliage on the trees. 



This material is strong enough so that if used several times through 

 the season it will be quite effective against the San Jose Scale. It 

 gives good protection from fungous, diseases ; the sulphur is quite effect- 

 ive against sucking insects, such as plant lice and scale insects, and the 

 arsenate makes it effective against Codling Moth, Curculio, and leaf 

 eating insects. 



AS TO SPRAYING PEARS. 



^J3 



Pear orchards generally do not require so much spraying treatment 

 as apples, though their pests are quite similar. As a rule, two treat- 

 ments will stand them in good stead — first, the winter treatment (No. 1), 

 (if the orchard has scale), and, second, the treatment after the blossoms 

 fall (No. 3). But the pear grower must remember that the Fire Blight, 

 which is perhaps tiie one greatest enemy to the pear grower, is not 

 reached by any spraying applications. Some pear growers do not spray 

 at all except when special occasion arises. The Kieft'er variety is gen- 

 erally more resistant to pests than the others, and it is seldom attacked 

 by San Jose Scale. 



SPRAYING FOR PEACHES AND PLUMS. 



Results from spraying peaches are less certain than with apples, but 

 with the mixtures and methods now in use they are more certain than 

 ever before. The control of San Jose Scale is relatively simple, the 

 control of Curculio is reasonably certain, and the control of the rot is 

 usually successful by the sprayings here recommended. But if the sea- 

 son be warm and rainy so as to wash off the spray, the Curculio and rot 

 may be destructive despite our best efforts. 



A system of spraying treatments which will give splendid results in 

 almost every year is as follows :

 gallon to 10 gallons water (see page 29) ; or, if you prefer, you may
