ROSE DISEASES 
Black Spot 
Actinonema rosae 
Produces purplish or discolored areas 
of considerable size on the surface of the 
leaves, causing them to drop. 
See Mtidew, this section. 
Cane Blight 
Affected wood turns a dark purplish or 
black color, with a sharply defined line 
between the sound and diseased bark. 
This trouble is due to a fungus which 
is apparently undescribed in plant disease 
literature. It infests stubs left in pruning 
and often develops down into the main 
branches, seriously injuring the bushes. 
May be largely avoided by proper prun- 
ing. 
pure 
pink to carmine 
Crown Gall 
This is the common crown gall which 
affects many species of plants. 
See under Apple Diseases. 
ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 
Rose Leaf Blotch 
Actinonema rosae (Lib.) Fr. 
Nearly as common as the powdery mil- 
dew. Irregular brown spots appear on 
the upper surface of the foliage. 
Climbing sorts are likely to be more 
immune than bush kinds. 
Spray with Bordeaux early before blos- 
som buds begin to form. Secure healthy 
stock for planting.

Rust 
Phragmidium subcorticium 
Affects the hybrid roses, causing the 
leaves to turn yellow and fall, with black 
or bright orange pustules of rust spores 
on the under side. 
See Mildew, this section. 
Mildew 
Sphaerotheca pannosa and 8. humuli 
Roses are commonly affected with two 
different powdery mildews quite different 
in appearance from one another. The first 
named is seen most characteristically on 
the hybrid roses and is particularly severe 
on the Crimson Rambler. It forms a 
thick, dense, felty white growth upon the 
green shoots, buds, and young leaves 
more than on the surface of the older 
leaves. This does not affect the tea roses. 
The latter are particularly susceptible, 
however, to the second fungus named, 
which produces a more delicate fungus 
growth upon the leaves and blossoms 
rather than the stems, giving them a 
crinkled appearance. 
The most effective treatment for these 
rose troubles consists in spraying the 
bushes occasionally with a solution of sul- 
phide of potash (liver of sulphur), one 
ounce to three gallons of water. Spray 
the under side of the leaves as well as the 
top and make up the solution fresh each 
time the spraying is done. If the bushes 
are also affected with plant lice an addi- 
tion of tobacco extract or cheap soap 
may be made to the spray. In bad cases of 
mildew further relief may be obtained by 
dusting the bushes thoroughly with flow- 
ers of sulphur while they are still wet 
with the spray.
