Many diseases Of nursery stock are
controlled by spraying. Begin spray

Be sure to look over apple trees
carefully. Cut out and burn all can
kers. Black rot has been increasing in
the state and since a great deal of
early infection may come from can
kered limbs, cutting out and burning
is necessary.
Last year the spring canker worm
was just as active in the state as the
fall canker worm. Therefore, just as
soon as possible, trees affected last
year should be banded with the tree
tanglefoot. The moths come out of
the soil the first two weeks in April
and attempt to crawl up the trunks of
the trees to lay their eggs on the limbs.
When raspberries are uncovered, be
sure to cut out and burn all of the
dead canes missed last fall. The gray
bark disease and anthracnose, also
snowy tree cricket and red-necked
