Scale Insects 
Lime-Sulphur, 1 to 8; 
Sealecide. 
Miscible Oils

of Lead 
When flower buds show pink, but before 
any have opened. (Other sprays are 
recommended for codling moth, below, 
will incidentally control troubles in this 
group). 
In severe cases of cankerworm use Paris 
Green 4 oz. in fifty gallons of water 
with twice as much slaked lime. 
Codling Moth 
Lime-Sulphur, 1 to 40, 
with 2 lbs. Arsenate 
of Lead. 
Arsenate of Lead, 2 
lbs. to 50 gals, wa¬ 
ter. 
(1) When most of the petals have fallen 
(calyx spray). 
(2) Approximately three weeks after the 
bloom. 
(3) Approximately ten w'eeks after the 
bloom. 
(4) Fifteen to seventeen weeks after the 
the bloom. 
After weather becomes hot (from about 
July 1) discontinue lime-sulphur and 
use Bordeaux with 2 lbs. Arsenate of 
Lead. 
Necessary in South where there may 
be three broods in one season. 
Blotch 
Curculio 
Lime-Sulphur, 1 to 40,

except two w'eeks after bloom in south. 
(2) Approximately five weeks after the 
fall of the bloom. 
(3) As in (3) under codling moth (above). 
Clean orcharding assists in curculio 
control. Spraying not always wholly 
effective. 
Arsenate of Lead may be omitted if no 
curculio is present. 
Sooty Blotch 
Fly Speck 
Usually checked as incidental results of 
applications recommended above. 
More common in regions where air and 
water drainage is poor. 
Bitter Root 
Bordeaux 
Where disease is looked for begin spraying 
in early summer, making applications 
often enough to keep fruit coated. 
Apple Rust or 
Cedar Rust 
Spraying not effective 
Remove cedar trees nearby. 
The rust cannot live without cedars on 
which it spends part of the year. 
Blight 
See under Pear, Fire Blight.

Curculio 
Brown Rot 
Leaf Spot 
Lime-Sulphur, 1 to 50, 
with 2 lbs. Arsenate

Similar to cherry, which see. 
Brown rot spreads very 
warm, moist weather 
controlled only if fruit is 
rapidly in 
and can be 
kept coated. 
PEAR 
Fire Blight 
Spraying ineffective 
In some cases where particular care is taken, prompt and severe pruning at the first 
sign of blight, disinfecting tools and wounds with corrosive sublimate solution, 
may check its spread to some extent. 
Scale Insects 
Blister Mite 
Pear Psylla 
Lime-Sulphur, 1 to 8; 
Sealecide. 
Miscible Oils. 
In dormant season, preferably early 
spring.

Practically all the other common diseases and insects on the apple are also found on the pear to some extent. See methods of control 
under apple (above). 
CHERRY 
Curculio 
Brown Rot 
Leaf Spot 
Shot Hole Fungus 
Lime-Sulphur, 1 to 50,

(1) Just before buds open. 
(2) Immediately after blossoms fall.

(4) Additional sprays if necessary at two- 
week intervals. 
In some localities it may be safer to 
dilute the lime-sulphur somewhat 
preventing foliage injury.
