PEACH AND PLUM INSECT.
Bulletin Showing How Worm May BE
Controlled.

SlehiSou COlleSe, NldTCn Zl-A. II.
Conradi and w. III. Barre, experts of
the Clemson college experiment sta
tton. have issued the following bulr
letin on controlling the worm in peach
and plum fruit:
The wormy fruit on peach and plum
trees Is caused by that notorious bug
known to every one as curculio. or
plum curculio. This is q warty snout
beetle, which lays its eggs in n cres-
cent shaped puncture made in the
fruit for that purpose. This crescent
shape mark Is conspicuous and we'll
defined OH the smooth skinned fruits
but on the fuzzy peach fruit the cres-
cent shape is frequently lacking,
sometimes appearin as a small round
puncture like that made by a pin while
In some cases 1t is entirely obsolete
This insect is best controlled with a
spray, made as follows:
Arsenate of lead, two pounds.
Fresh unslacked lime, two pounds
Water. SO gallons.
Mix the arsenate Of lead with water
In pail till it has assumed the CON
sistency of whitewash, then addthis
to the barrel of water. Slack the lime
and add this milk of lime or white
wash to the same barrel and the spray
Is then ready to be applied. Every
plum should have a good agitator in
order to keep the mixture stirred.
The time is important in preventing
scorching Of foliage by any soluble
arsenic that may be present in arsen-
nate or lead. Only fresh whitewash
should be used. Air Stacked lines
nave no value for this purpose.
How to Spray.
First, spray thoroughly when about
90 per cent. Of the petals have fallen.
second, repeat in 10 days.
In small orchard these insects NAV
be partially controlled by jarring the
trees every other morning and collect
ing the insects upon a sheet spread un-
der the tree for this purpose. The lar
ring should be begun at the time rec
commended for the first spray and con-
tlnued Tor period of six weeks, or un-
I'll no more beetles can be Jared from
the trees. Jarring should be done early
In the morning when the air is cool.
inc orchard should be thoroughly
cultivated and the soil stirred at tho
surface for period of two weeks, be-
ginning seven weeks after full bloom
Jarring is laborious. But the spray.
combined with the cultivation, is very
efective. In small orchards the col
lection and destroying the fallen fruits
during one season is also an excellent
practice.
Brown Rot.
Brown rot Is fungus disease. which
as the name indicates, causes a rottinp
or fruit, especially peaches and plums
lt Is the most prevalent OF the peach
diseases and is the one that il re-
sponsible for practically all decayed
fruit that we find in peach and plum
orchards. The disease is easily recop-
nlzed by the brown color OF the fruit
as 1t hangs on the trees. Such fruit
Is usually soft and mushy when fresh.
~ rotted, but later becomes dry and
hard and remains on the trees as rot
ted mummies. If such rotten beaches
and plums are examined carefully a
number OF small pustules will be found
covering the surface. These pustules
are masses Of tiny brown seed. like
Codes (spores), which serve to pro-
pagate and spread the disease. When
one OF these little spores lodges on a
peach or plum and finds conditions
favorable, it terminates and grows
there and produces the rot. The dis
ease always thrives best and does
most damage during moist, warm
weather.
The first step In controlling this dis
ease is to collect and burn all of the
old rotten fruit on and around the
trees. This eliminates the most i'm
portant method OF infection and makes
the disease more easily controlled by
spraying. There are number of fun
gicides commended for spraying for
brown rot. but the best results have
been obtained here with Bordeaux mix
ture;
Eight pounds of sulphate (blue
| stone.)
Four pounds of quick lime.
Fifty gallons Of water.
This should be appied, first as soon
