Resistant Varieties Of Cotton
to Wilt Disease


to Wilt Disease
/. D., Savannah, Gal, writes:
have a piece of land that every
time l plant il 20 cot !On it dies
of Hack root. Can you give me
the names of any varieties that
arc resistant to this dcscase and
where could get seed o: themt
Also where can -ecure cal
ciGIn arsenate?
There are certain strains of cot
ton which are quite resistant to
black-root. This is also known as
the wilt disease, and it is caused
by a fungus which obtains entrance
to the roots of the plant. grows up
through the water-ducts and chokes
the plant to death. This fungus per-
sists in the soil for a long time, and,
on that account, it is difficult TO
eradicate or control it. The best
practice is to rotate your crops,
plant resistant strains and keep
cotton off the affected land as much
as possible. This disease may be
transmitted from one field to anoth-
er on the shoes of workmen, or by
the implements used in cultivatlng
the land. You should guard against
its spread therefore through the
means indicated. Among the Varie-
ties of cotton most resistant to the
wilt disease are Covington Toole,
Petty's Toole, Council Toole, Dix
afifi and Lewis IS. You should not
have great difficulty in securing
good. seed of these varieties at a
reasonable price.
Your county agent should be able
to put you in touch with individuals
in Savannah who are handling cal
cium arsenate and who should be
able to supply you with what you
need at a reasonable cost. Your
county agent can also give advice
relative to the best time and meth
cd to follow IN applying this ma
terial for the protection of your
cotton crop.
Soy Beans and COwpeas Com
pared for Hay and Grain
f. d. W., COrnelia, Ga,
writes: VIII the 0-tOO-tan soy
bean do we'll i'm this section, and
is it better than COwpeaS for
hay? I have heard that you are
recommending a bean which is
better than the O-tOO-tan. What
is the name of it? Are there any
peas or beans which are inn
mune to the attack of the Next
can bean weevil?
The O-too-tan soy bean is rath-
er a long-season variety and it may
not do so we'll in your section as
some other variety. We are still in
clined to believe, however, that if it
is planted soon enough that it will
mature before frost. It is an excel
lent strain for hay and grain pro-
duction. 1t is primarily valuable as
a hay crop. The stems are fine and
rather numerous, and it is quite a
leafy variety. 1t is also easy to cut
and cure. In your section. it ought
to do quite as we'll for hay making
as cowpeas, and it ought to give as
large a yield. We have recommend
ed the Laredo soy bean because we
believe it superior to even the O-too
tan for hay and grain production
The seed are vrey small so that {
relatively small Quantity of grair
will seed a rather large area. We
have grown this crop sufficiently
long to be satisfied as to it's merits
and we have this year distributed
the seed as widely as possible. We
only had a. limited amount at best
however, to send out, and it has al
ready been distributed. We have ha6
no complaints as yet relative to the
Mexican Bean Weevil destroying
the soy bean crop. It will attack
some varieties much more readily
