A concentrated liquid sulfur fungicide in soluble form. 
When sprayed, decomposes into sulfur in its finest colloidal 
form on the fruit and foliage. For apple scab, brown rot of 
peaches, plums, and cherries; for blight and rot on potatoes, 
tomatoes, and melons. One of the finest bean sprays known. 
Used for mildew and rust on flowers and shrubs. Dilutes 1 
gallon to 200 gallons of water. For brown rot at picking-time 
on peaches and cherries use Yz gallon Sulfocide and 1pounds 
of soap to 100 gallons of water. 
Fungous diseases can be prevented, but they can seldom be 
cured. Therefore early spraying is very important, and addi¬ 
tional sprays should be put on at frequent intervals to pro¬ 
tect the new growth.

SPRAY 
CATALIZER 
A spreader, sticker, and safener for sulfur sprays. Particu¬ 
larly effective for use with lead arsenate, lime-sulfur, or lead 
arsenate Sulfocide spray mixtures. Not only does it control 
the normal breakdown of polysulphides, but it effectively 
blocks the usual reaction which occurs between lead arsenate 
and lime-sulfur or lead arsenate and Sulfocide solutions when 
the two are combined. Combinations to which Spray Catal- 
izer has been added do not blacken, even after hours of stand¬ 
ing. There is no immediate black sulphide formation. Takes 
the place of calcium caseinate, skimmed milk, and other 
commonly used spreaders and stickers. 
Always use Spray Catalizer whenever using lime-sulfur or 
Sulfocide.
