AhRACNOsE OR BOIL ROT IN
COTTON.
S. H. A., Porterdale, Ga, writes:
send some diseased cotton hollis. Our
cotton is badly affected in this section,
and we want to know what it is. Please
tell us the cause and remedy.
The diseased bolls sent in are affected
with what is known as anthracnose. This
is sometimes called locally the boil rot.
The disease is characterized by the ap-
pearance on the boil of a spot of dull
reddish color The spot enlarges and
becomes of dull purple almost to the
edge. In the middle it is at first black
and later becomes grayish and covered
with a pink powder. This powder is COM
posed of spores of which there may be
thousands on one affected boil. The dis
ease attacking the bolls in various stages
of development causes severe injury and
This trouble causes millions of dollars
of loss in Georgia every year and is
being spread on to new areas constantly
by the use of diseased seed, and the
fact that no effort is made to destroy
! the spores.
The disease is due to a fungus which
may be said to be true plant, though
of simple structure, belonging to one Of
the lowest orders of the plant kingdom.
The plant consists of two parasitic
mycelium and spores. The mycelium

of it's habit of living on the cotton plant,
the fungus is known as a parasite. The
fungus passes the winter in various
ways, and begins its development in the

work of destruction again
This. as you will see, is a most diff
cult and dangerous disease to contend
with since the spores are exceedingly
hard to kill. The best methods of fight
ing ii so far devised are a rotation of
crops, which tend to starve it out. The
seed may be treated in one of several
ways before planting, as for instance,
with a solution of formalin in the ratio
of l pound to so gallons of water. The
seed should be carefully dried after the
treatment and kept in a place where they
are not likely to suffer retnfectIon. The
selection of seed from resistant plants
will enable the control of the disease to
large extent, and the choice of varieties
has much to do with securing an immune
strain since some varieties are much
less subject to the attack than others.
on the college farm we have been en-
deavoring to produce strain of cotton
resistant to this disease for several
years by selecting plants from a field
which was originally badly infected with
anthracnose Much progress has been
made along this line, and IT now seems
that a strain quite resistant to this
trouble will ultimately be developed
Every farmer should treat his seed this
year, selecting ii originally from the
strong, vigorous plants growing in in
fected areas in his field. Then, by prac-
ticing a rotation of crops and ginning
his seed at home on hand gin or some
other device that win prevent its rein
lection, they should be able to control
this trouble to a considerable extent
