THE COMPLETE DORMANT SPRAY 
"Makes a Tree Outgrow Its Troubles ” 
Since 1904, Scalecide has been famous for its effectiveness 
against the San Jose scale and all other scale insects, because 
it has always been a miscible oil of the highest quality. But 
Scalecide is not only a scale spray; it kills all other pests which 
winter on the tree. It is the complete dormant spray. Applied 
as a delayed dormant spray in the spring, diluted 1 to 15 
(12 gallons to a 200-gallon spray tank), Scalecide controls 
aphis, European red mite, pear thrips, and red bug; diluted 
1 to \ 2}4 (15 gallons to a 200-gallon spray tank), it also con¬ 
trols leaf-roller. Applied in the fall (1 to 15), Scalecide con¬ 
trols peach leaf-curl and pear psylla. Either fall or spring 
spraying with Scalecide (1 to 15) controls scale, bud-moth, 
case-bearer, leaf-miner and fungous cankers. 
Scalecide-Sulfocide Combination 
Scalecide 1 to 100, combined with Sulfocide 1 to 200, is the 
ideal pre-pink and pink spray for apples. It not only controls 
late-hatching aphis and aphis which the ants bring on to the 
trees after the dormant spray, but also thrips, red bug, and 
soft-bodied sucking insects. 
Spray Ornamentals with Scalecide 
Spray any tree or vine which drops its foliage in winter 
with Scalecide, just before the buds start in the spring. Spray 
lilacs, rose bushes, and other shrubs. Use Scalecide, I to 15, 
on maples, dogwoods, elms, and other shade trees. This spray 
is for San Jose scale, oyster-shell scale, scurfy scale, tulip 
scale, red mite, woolly aphis, green aphis, etc., as well as 
building up the general vigor and vitality of the trees. 
For conifers, spruces, pines, etc., spray with Scalecide, I to 
20, just before the new growth starts in the spring. 
For evergreens, euonymus, etc., spray at the same time 
with a dilution of 1 to 25. 
Para-Scalecide Method 
For control of peach borers stir in 1 pound of Paradow 
(paradichlorobenzene) to 1 gallon of Scalecide. Dilute this 
combination with 7 gallons of water and spray ground around 
base of tree and trunk 8 inches above the ground, using ap¬ 
proximately pints per tree. Mound after application.

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 % gallon Sulfocide and pounds 
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.
