Formula to Kill Green Apbi,
Query-Will you please furnish me-
with a practical formula for the kill
ing of the green aphis? Does winter
pruning have tendency to reduce the
production of fruit?
Ans. To destroy the green apbism
the apple, plum or prune spray with
sulphur lime wash when the leaves are
off the trees. Kerosene emulsion is
effective when the insects appear. Re.
peat before the leaves curl if neces.
sary. Pruning fruit trees during
winter time always tends to reduce the
production of fruit buds, or flower buds
upon the trees; and while this is not
a serious difficulty in the western part
of the United States, since the trees
produce more flower buds than are US.
ually needed, yet with certain vane
ties the loss of the buds from winter
pruning may become more or less ser.
ious. Varieties that are shy bearers
may better be pruned during the. sum-
mer time, which will encourage rather
than discourage the production Of
fruit. 1t is interesting to notice how
a fruit crop may be lessened or in
creased by winter or summer pruning.
The Plant Stores Food.
Query-Enclosed find specimens
from my apple orchard. The straight
twigs show the sting of some insect,
and engagements where the fruit grew
last year. Every place where an ap'
pie grew is more or less: enlarged, with
apparently diseased wood in the Gen.
ter. Is this serious?
Ans. The enlargement of the apple
tree twigs is due to the plants stor-
ing up plant food for the development
of fruit blossoms during the next year
Rarely do we find such marked en-
largements as are on these specimens
but we consider them a splendid sign
that the tree is in good, healthy bear
ing condition. You will discover, Dy
studying these trees during the grow.
ing season. that the enlargementsswiN
decrease in size as the apples increase
in size. This Shows that the tree
stores up this reserve, in order TO oe'
velop a full crop of fruit. The twg'
also show a few of the San Jose scale'
and we would advise you to look al'ci
them carefully. The second SET u
twigs shows injuries by the locust
