Club Root on Turnip. 
Experiments have shown that an appli- 
cation of lime at the rate of about 100 
bushels per acre when the land is plowed 
in the spring is a reliable method of con- 
trol. 
Damping Off 
Caused by soil fungi of several varie- 
ties. The young plants slough off at the 
ground. The trouble occurs when they 
are crowded or conditions are too moist. 
Surface soil should be given a chance to 
dry. Mainly a seed bed trouble. 
Downy Mildew, Leaf Blight and 
White Rust 
Occur upon plants of the mustard 
family, including the cabbage. 
If treatment seems necessary use Bor- 
deaux mixture. 
Fusarium Wilt 
This trouble has become very destruc- 
tive in the cabbage growing sections of 
the Eastern states and bids fair to rank 
with black rot in importance. It causes 
a yellowing and wilting of the plants. 
ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 
The only remedy suggested is the breed- 
ing of resistant stocks. 
Root Rot, Stem Rot, Rhizoctonia 
Due to the same fungus which attacks 
the potato. It would seem that general 
sanitary measures and rotation is the 
only practicable remedy.
