lem can be materially aided by the re
duction Of all diseases attacking fruit
trees.
The pear blight, which also attacks
apples and commonly called Fire
Blight" is especially bad in certain re-
gions of the state where pears and APP
pies are grown. 1t has been found on
apple trees in Oconee county and prob
ably occurs in many other counties of
the state where apples are grown, but
which have not yet been visited. y
very bad case of this blight was recently
found on pear trees in Jackson county.
1t is very easy to detect this disease
wherever it is present at least this is
the case in most instances, where the
disease has been observed For ex-
ample, the infected branch dies back
beginning from the tip, the leaves turn
a scorched brown, wither, but haroly
ever drop from the infected branch. The
disease is caused by a bacterial organ
ism which does it's work inside the tWis
or branch For this reason spraying IS
of no value, not even as preventative
The only treatment for this disease IS
to make a careful examination when the
trees are in the dormant state; that Is,
now" for "cankers" and other dead
areas of the bark, twigs and larger
branches where the disease is carried
over winter and from which areas new
infections result the following spring
and early summer. Cut out all such in
fected areas, being sure that the cut
goes back to sound and healthy wood.
After each cut wipe off the cut area and
knife with sponge moistened with.
3 per cent. corrosive sublimate solu-
ton Zone tablet to one pint of water),
recommended by WhetZel, of Cornell
university. This disinfectant can be
carried in a bottle to which sponge
may be attached and both sponge and
bottle attached to a strong cord which
is thrown over the shoulder. Be sure
the infected branches are removed from
the orchard and burned after the cutting
process is over. 1t is necessary to disin-
feet the knife after each cut or else the
disease is spread over greater area
and your previous work has gone for
naught. 1t would also be we'll to paint
over the cut areas with coal tar prepa-
ration or white lead, which prevents
cracking of the limbs and the entrance
of other disease pores. The "t1re
Blight seems to be much more serious
in trees which make a rapid growth
for the season, and for this particular
reason, it would seem advisable If pears
are to be grown, that they should be
left in sod. From time to time after
should be made for signs of diseased
twgs and larger branches.
Black-rot cankers in the apple or
chard should also be removed at this
time and burned. Methods of disintec-
ton recommended for the Pear Blight
should be practiced.
BEST COTTON FOR NORTH GEORGIA
81. g., Lyerly, Ca, writes: What kind
of cotton do you think would suit US mere
in north Georgia? What about fertilizer
this season? Would it pay to pay high
price for that with potash in it, or leave
the potash out?
A cotton map of the state Of Georgia,
made at this institution as a result or
data collected last year, indicates that
Clevelands Big Boil is the most extern
sively cultivated of any variety of cot
ton in Georgia. 1t appears that this va
riety is grown to a considerable extent
not only in your county but in the ad-
joining counties as we'll The next most
extensively grown variety in your sec
ton of the state is Half-and-Half, fol-
lowed by Sunbeam, Broadwelrs and
Landlords Half-and-Half has proven
to be subject to anthracnose and on
this account we are somewhat chary or
recommending its cultivation. We have
also found Trice, Cooks and Hooper's
early strains are good varieties. Judg-
ing from the experience, observation and
information we have mad, We would be
disposed to say that an early maturing
variety of ClevelaAd's Big Boil should
be wei adapted for growth in your sec
ton of Georgia.
There is a good deal of difference in
the various strains in the matter OF
early maturity and you should purchase
and use only seed which is guaranteed
to be one Of the earlier strains. No
doubt there are farmers in your county
who have a better strain of seed avail
able for Planting than others. The car
Hest Straih of cotton we have come
across as yet is College No. ]. This
was developed here at this institution
but We have only a limited amount OF
the seed and so its general cultivation
cannot be undertaken this year.
In order that you may have the best
chance of securing a good yield of cot
ton in your section of the state you
should prepare the land we'll in advance
of planting. Enrich is literally and al
low it to firm well before the seed are
sown.
AS to fertilizer, that opens up a big
proposition. 1 would use those materials
which / could purchase at the most rea-
sonable price. If that happens to be
equal quantities of cottonseed meal and
acid phosphate, good and well. If you
can find some carrier of nitrogen which
will furnish available plant food at a
lower cost than cottonseed meal, use it.
Dried blood, tankage, nitrate of soda,
sulphate Of ammonia, calcium cyanide
and other materials are all valuable as
sources Of nitrogen. Personally l hard
ly think in your section of the state
you would be justified in paying the
price potash would cost you. If it comes
in the fertilizer as an incidental propo
sition, as would be true where you use
phosphoric acid and cottonseed meal, 1t
is all right to have it, but to go out
any pay, say Csc or soc an pound for
available potash l think would be a
doubtful proposition so far as the In
terest of the farmer and producer is
concerned Potash is necessary in many
of our soils, but there is price which
you can hardly afford to pay for it if
you expect to make profitable return
on your farming operations.
