AGAINST
"WORMY" FRUIT

The fruit crop of nineteen-fOurteen
promises to be very good one. The
trees have passed the winter in good
shape and unless a severe freeze oc-
ours within the next few weeks the
indications are that Kentucky will en-
JOY a banner fruit year. The interest
in the production of better fruit has
been very gratifying and many orch
ards that have been neglected for
some time past have been pruned,
sprayed and otherwise put in cOndi-
ton.
The spray that has been applied up
to the present time gas been the dor
mant application for San Jose scale
principally. Many growers who are
just starting to care for their orchards
feel that this application is sufficient
They should remember that this APP
pilcation is made more as a protection
to the tree and nc: SO much for the
fruit itself. The application that is to
show greater results from a fruit
standpoint has yet to be made, and
it is known as cOdling moth spray
The codling moth is the insect that
causes the apples to become "wormy'
and drop off permanently. 1t is safe
to say that over fifty per cent of the
apples raised in the State are infested
with the larvae of this insect The
moth is grayish brown in appearance
and usually flies at night. The female
moth deposits her eggs on the calyx
end of the fruit and on nearby leaves
and branches about poisoning time.
The eggs hatch in from five to ten
days after they are laid. AS soon as
the worm matches it crawlS to the
nearby apples and usually enters the
open calvx of blossom end.
Advantage should be taken of the
fact that the worm enters the open
calyx of the apple and an attempt
should be made to spray the trees just
after the blossoms drop and before
the calyx cap closes. If the spraying
is delayed too long the calyx cap clos
es around the worm and it is impOssi.
BILE to reach it with poison. This
spray should be directed down into
the blossom with as much force as
possible.
Arsenate of lead and Paris green
are the principal poisons used in COM
batting this insect. Of the two, arse
nate of lead is preferable because it
adheres better and because it is not
so liable to burn the foliage. 1t
should be used at the rate of three
pounds of arsenate of lead to fifty gal
Ions of water. Paris green should be
used at the rate of five to eight oun-
ces. to fifty gallons of water. One
gallon of lime-sulfur should be added
to forty gallons of the spray because
of it's value in checking the different
fungous diseases, such as black rot
and apple scab.
In this section there are two broods
of codling moth in year. The Sec
ond brood usually makes its appear
ance from the middle of July to the
first of August. The same spray as
given above may be applied. Ii bit
ter rot is troublesome, Bordeaux mix
ture should be substituted for the
lime-sulfur.
These sprayings are very important
from fruit standpoint. Particular
effort should be made to place some
of the material in every calyX cup. 1t
is not so necessary to try and spray
every leaf, but the operator should
aim to reach all of she fruit.
