adding water as directed. To disregard this feature will 

 usually mean injury to the foliage in proportion to the extent 

 of the departure from directions. 



Atomic sulfur. 



This is a proprietary name for a commercial form of 

 sulfur that is exceedingly finely divided. It has been rec- 

 ommended and used to a limited extent in place of the self- 

 boiled lime-sulfur mixture. While the results, on the 

 whole, have been fairly satisfactory, this form of sulfur 

 does not stick as well as the self-boiled lime-sulfur mixture, 

 and it is not as effective in controlling brown-rot and scab. 

 Under some conditions, however, it may be advisable to 

 use it. As a substitute for self-boiled lime-sulfur, it is 

 applied at the rate of 5 pounds to 50 gallons of water. It 

 seems probable that this material would be successful also 

 in controlling the various mildews. 



Bordeaux mixture. 



It has been noted previously that this old and much-used 

 fungicide has never been of much service to the peach- 

 grower in controlling diseases of the fruit because it burned 

 the peach foliage so badly. With the development of the 

 sulfur sprays, it is now of even less value in most respects 

 than formerly, when peaches are concerned. Its use as a 

 dormant spray, however, has been mentioned, particularly 

 in connection with the California peach-blight or Coryn- 

 eum-blight (page 270). For this purpose the 4-4-50 

 formula is recommended. 



The method of preparing this mixture is doubtless too 

 familiar to every fruit-grower to require extended descrip- 

 tion here. Briefly stated the procedure is as follows :
