about.
Where cotton wilt is severe, it is US

which causes root-knot is present also.
The first step is the reduction Of the
injury from root-knot by crop rotation.
On your wilt infected land, start. ro-

Plant corn this spring with velvet

the number of nematodes to increase.

The College of Agriculture is trying
to collect all the data possible on plant
disease conditions in the state, and
should be glad to receive specimens or
diseased material, whereupo' nit will fur
nish farmers the latest information re-
garding the disease, including methods
of control. Most of our troublesome
diseases can be prevented or their-se'
versity greatly lessened by adopting the
control measures that have. oeen worked
ont bv the United States department of
agriculture and the state experiment
stations, and ye are ready at all times
to advise regarding your plant disease
problems.
The large annual loss from cotton an
thracnose can be prevented. The land ION
which this disease was present in last
years crop should not be planted to cot
ton for two years. The fungus which
causes authracnose will die out of the
soil in this time. This fungus is also
carried in the seed, and there are two
ways of obtaining disease-free seed. Sc
lect cotton for seed from field which
is not infected, or from stalks wsich do
not have any diseased bolls and which
are not close to infected stalks. Care
must be taken to keep this seed from be-
coming mixed at the gin. Infected seed
can be freed from anthrocnose by keep
ing them three years without planting.
The organism in the seed dies in this
time, and if the seed are planted on dis
ease-free soil no anthrocnose will de-
velop.

count of Investigations undertaken at

concerning this disease, which is at
present quite widely distributed In
North Carolina. symptoms above the
ground distinguishing the disease from
other apple root rots have been found,
but the roots have been found covered
with the black fungus growth.

Now is a good time for fruit grow
erS of the southeast to begin practic
ing the above recommended treatment in
reference to peaches, and plums also, |
wherever the latter are grown, because
brown rot attacks all pom fruits indis
criminately. The disease has been found |
especially prevalent in counties of the
state whers peaches are grown. for ex-
ample, many peach orchards visited In
Jackson county showed the mummied
fruits still perslsting on the trees late
i'm the fall. These mummied fruits
should be knocked off the trees and
plowed under, so as to prevent a rein
lection the following spring. The saw
ing in money and time will be decidedly
in evidence the following year in quail
ity and amount of crop produced. Be-
sides, the peach grower owes this much
to his community, state and national
government in the campaign for a great
