SPRAY CALENDAR. 



This calendar has been prepared to answer the question, 

 so often asked, when to spray, what to spray with, how to spray, 

 and what to spray for, thus obviating the error to use the wrong 

 spray for any given insect or fungus. 



All fruit trees should be sprayed in the fall, as soon as all 

 the leaves have dropped, with sulphur, lime, and salt; if no 

 scale are present, full strength of bordeaux mixture will be 

 found sufficient. 



SULPHUR, LIME, AND SALT. 



This is a winter spray, and used for all scale insects, pear- 

 leaf blister mite, green aphis, twig borer, bud moth, and 

 clover mite. 



HOW PREPARED. 



Ingredients — Lime (unslacked) , fifty pounds. 

 Sulphur, fifty pounds. 

 Stock salt, fifty pounds. 

 This will make one hundred and fifty gallons of wash. 



Directions — Slack fifty pounds of lime, then add the fifty 

 pounds of sulphur, boil it over a brisk fire for one hour, then 

 place all the salt with it in the boiler and boil for fifteen min- 

 utes more, then add the necessary water to make one hundred 

 and fifty gallons. This solution should be used at a tempera- 

 ture of at least 100°. Before using, strain it. The utility of 

 this wash depends a great deal upon the strength of the sul- 

 phur. It is therefore recommended that those who use this 

 wash have a Beaumes scale for acid. When it shows 8° when 

 cold, it is of the proper strength. These scales can be ob- 

 tained through any druggist at a cost not to exceed fifty 

 cents. 



This combination is the result of Mr. Emile Schanno's ex- 

 tensive experiments in the fourth district.
