commerce has received the follow
ing communications in reference to
the tomato bligh, which has been
troubling the farmers of this locality.

Replying to yours Of July IA, ]
will say that very evidently the trou-
bic with your tomato plants is flu
sarium disease. resident in the soil,
which attacks the root systems of
the plants. choking up the passages
through which the sap circulates, and
finally causing the death of the
plants. The fusarium organism eaus-
ing this disease being resident in the
soil Is exceedingly difficult TO COM
bat. and in fact. cannot be econom-
ieally exierminated. The difference
between the plants which you make
mention Of J. doubtless due to re>is-
tanee Of individuals TO the disease.
IL Is frequently possible 10 select
-eeds Of resistant individuals with
the result that the best quality is es-

damage lssssned BY this means
The following Is from D. +. Mer-

tsoiaaist Of the New Mexico Agricul-

The trouble with the tomato
plants i likely one of three diseases
which have a good many character

perhaps. You will understand that
the diseases of the tomato, along
with q good many other plant di-
ssases have not been worked out full
~ even as to cause, let alone the con-
troll. But work is being done ON them
and We have hoped for the future.
We have likely the Vme disease in
our tomatoes at the farm. but with
other work We are into. have not been
able to take up these diseases. Flor
ida and California have done some
thing with these and | give YOU the
benefit Of their findings.
FUNGUS BLlGHT-Due 10 n
fungus fusarium. May attack most
vigorous plants or those low in vi
tally. First sign usually the yellow
ing Of the larger lower leaves. They
usually dry from the tip later. The
leaf stem and the plant stem near
the yellow leaves when cut across
show darkened veins. Later the di-
sease spreads more or less rapidly
to the rest Of the plant.
''Sinee this Is due to fungus that
lives over in the soil there has been
no means found for preventing it
attacking plants except to rotate the
crops 80 that tomatoes Will not come

three year intervals.
