WISCONSIN HORTICULTURE 
March, 1919 
was fcmnd near Rice Lake, Barron 
county, and later several other 
fields were found in the vicinity. 
Through the able work and lead- 
ership of County Agent Cuff, Bar- 
ron was well supplied with spray- 
ers and spray material, and, when 
the warning was sounded, all the 
spray machines were hauled out 
and put to work. The results at 
digging were : 
Sprayed Unsprayed 
°/c rot % rot 
High ground 5 35 
Low groundl8 50 
Thorough spraying with Bor- 
deaux mixture held the blight in 
check until the frosts of Septem- 
ber killed the vines and the dan- 
ger from blight was over. 
The injury to potatoes caused 
by frosting is, of much greater im- 
portance than it is usually con- 
sidered. It is a matter of common 
knowledge that when potatoes are 
frozen solid they become soft up- 
on thawing and are known to the 
trade as “leakers”. However, 
when a potato is slightly chilled, 
a few degrees below the freezing 
point, there is no external visible 
indication of damage. It is only 
when such potatoes are cut open 
that the result of chilling is ob- 
served. They may show dark 
lines in the region of the vascular 
ring beneath the skin or a net 
work of discolored strands in the 
flesh. The discoloration is always 
more marked at the stem end than 
at the eye end of the tuber. 
Cabbage diseases always claim 
considerable attention from the 
plant pathology department and I 
am pleased to say that the yellow 
disease, which a few years ago 
threatened to ruin the cabbage 
growing industry in the lake 
shore region of Racine and Keno- 
sha Counties, is now practically 
under control through the use of 
the specially selected strain, AVis- 
consin Hollander. There is ap- 
proximately a thousand pounds of 
this seed available for 1919. Mr. 
AY. J. Ilansclie, Route 4, Racine, 
handles this seed as he did last 
year. 
Cabbage black leg, a fungus dis- 
ease, has been found more serious 
this year than in any previous sea- 
son when this crop has been under 
observation. Virulent attacks 
have been made on fields of AVis- 
consin Hollander as well as other 
strains and varieties. Borne fields 
of Hollander and domestic cab- 
bage were nearly worthless. 
Black leg came the nearest to pro- 
ducing an epidemic of any plant 
disease that was observed in 1918. 
The fungus causing black leg lives 
over with the seed and on old 
stumps and leaves so that two ave- 
nues of control should be consid- 
ered (1) sound seed, disinfected; 
(2) rotation of seed bed and field. 
Seed treatment will not be an ab- 
solute guarantee against black leg 
because some of the fungus 
threads may get down under the 
seed coats into the very heart of 
the seed beyond the reach of any 
disinfectant. Formaldehyde so- 
lution, 1 oz. to 2 gal of water, for 
20 minutes has been recommended 
tor cabbage seed treatment, but 
does not prove quite as satisfac- 
tory as corrosive sublimate 1 :1000 
which can easily be made up in 
smrll quantities from tablets ob- 
tainable at any drug store. There 
is, however, a very great promise 
of being able to use heat in disin- 
fecting cabbage and other seeds 
according to preliminary results 
of experiments now in progress. 
The use of the formaldehyde 
drip attachment on onion seeders 
was again successfully demon- 
strated in fields south of Racine.
