2. Lime and Sulphur: For destroying scale and fungus growths, 
as a dormant spray, use: i gallon of the wash to 8}i gallons of water 
for summer work, i gallon of wash to 42 gallons of water.

the foliage is out, as it discolors the leaves and ruins the appearance 
of the tree. It should be applied on a quiet day so that the spray will

be sprayed should be dry, so do not apply after a heavy frost. 
The odor is always disagreeable.
