SCALECIDE 
A Miscible Oil Dormant Spray 
FOR USE ON FRUIT AND SHADE TREES, SHRUBS, EVERGREENS, AND VINES 
Dormant and Delayed Dormant Spray 
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 r 
to I2>£ (15 gallons to a 200-gallon spray tank), it also controls 
leaf-roller. Applied in the fall (1 to 15), Scalecide controls 
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. 
No Nicotine Required 
The fact that Scalecide, applied as a delayed dormant spray, 
controls aphis without nicotine, means much more than the 
saving of cost of the nicotine; it means the control of aphis 
year in and year out by the simple method of spraying an¬ 
nually with Scalecide. 
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. 
This combination is a strong fungicide for first protection 
against scab, but it costs less than Nicotine alone, not count¬ 
ing the scab-protection at all. 
It gives the foliage a lustrous waxed green color, and when 
harvest comes the fruit is noticeable for its beautiful color 
and finish. 
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, 1 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.
