It may be laid down as a general rule

Considerable "damping on" is snow
ing up in the cabbage and seed peds,
New soil should, of course, be used each
year in the beds, and. if possible, II
should be steam sterllized. After the
disease has made it's appearance in a
bed not a great deal can be done in the
way of eradication. Thinning out the
plants so that there is no crowdlng
of coarse sand about the stems renders
conditions less favorable to the de-
Velopment of the organism.
From the experience OF last season
il will be we'll to select new piece
of land for the cabbage planting. Last
spring many agents advised that en-
tire fields had been destroyed as
result of FELLOWS, a fungus disease
years. Infection of the fleld may take
place in the following ways:
/. Diseased seedlings.
2. Diseased material scattered over
in on agricultural implements, or the
roots of Seeding tomato or other plants.
3. Infected seed.
A large percentage OF the spanish
peanut crop was affected with leaf spot
the past season. In many cases the
disease was carried down the stalk and
appeared on the peas themselves. In
selecting seed for, next year, be very
ing disease-better select seed from
healthy vines only. The disease is
carried over in the soil on the diseased
vines or is brought in on manure re-
sulting from diseased vines. Crop ro-
tation is an important factor in con-
trolling the disease.
Powdery mildew showed up on many
varieties of the coWpea during Sep
TENDER. Occasionally the disease proved
so severe that the leaves were killed
and dropped. thus destroying the forage
value of the plant. Fortunately, the
season was dry and the damage was
small.
In selecting seed Irish potatoes one
should discard any tubers with a scab-
by or warty surface or any, which upon
being. cut show discolored vascular
ring lat the stem end). All suspicious
specimens should be sent to the pathoi-
Cgist for determination. The good seed
should then be treated to destroy dis0
ease organisms on the surface. The
methods of treatment are as foiloWs
~ Corrosive sublimate, one part to
1000 parts water. Clean tubers soaked
for one-half hour; then washed ana
spread to dry.
C9) Formaidehyde. one part CONNER
cial 40 per cent? to 240 parts water.

About one gallon OF solution is used
per bushel OF potatoes treated; thus for
100 bushels of seed there will be re-
quired:
ID Fourteen ounces of corrosive
sublimate to 100 gallons of water
CD One pint of formaldehyde to 100
gallons of water.
