REPORT OF STATE BOARD OF HORTICULTURE. 135 



SPRAY NO. 1. 



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. 



FOR SAN JOSE SCALE, GREEDY SCALE, AND TURTLE-BACK SCALE, 



Sulphur, lime and salt in the fall as soon as the leaves have 

 dropped, and again in the spring before the buds begin to 

 swell. 



FOR GREEN APHIS. 



First application with sulphur, lime and salt in the fall 

 after leaves have dropped, followed in the spring with Spray- 

 No. 14, as they appear on the trees. 



FOR PEAR-LEAF BLISTER MITE, 

 (Phptopfus Pyri.) 



Until recently the rough, brown-looking spots seen on the 

 pear trees were passed by as being the fungus that attacks the 

 pear so generally here, but upon closer examination it was
