when the first worm is about one-fourth inch long. Then you can
kill them easily. I haven't seen one vine hurt by fire worm except
that one spot.
I hope the Wisconsin growers will have a good crop, so as to keep
up our reputation among our good customers. In Chicago we have
a lot of customers of Wisconsin berries. They like our berries.
Sometimes we get a premium of $1.00 a box over other berries, be-
cause they are so uniform in size and color. We haven't many, and
can't establish a market for them until we get enough. A few boxes
don't count. A high-class customer with a high-class trade will get
them, and he pays the premium.
PLANNING FOR STATE-WIDE CRANBERRY
INSECT CONTROL
By S. B. FRACKER, State Entomologist
An entomologist is sometimes known as an alarmist because it is
his business to discover dangers before they arrive and point out
measures which should be taken in advance. He is not always able to
do this and sometimes insect pests and plant diseases prove to be less
injurious than was anticipated. In many cases, however, the alarm
proves to be more than justified and new introductions often result in
far greater injury than was expected.
In talking to the Wisconsin Cranberry Growers' Association, how-
ever, it is not necessary to take the attitude of an alarmist. From
sad experience you are familiar with the damage which can result
from insects feeding on the vines or on the fruit, or from diseases
causing faliure to set fruit, or cranberries rotting in storage. No two
years have shown just the same record but in some seasons the dam-
age from this source has been the most important factor in determin-
ing the total crop.
The ideal conditions for insect and plant disease control, in the case
of any farm or garden product is to have the same insects and dis-
eases to cope with each season and to discover some method by which
they can always be prevented from developing. When such a condi-
tion exists it is not necessary for the grower to determine each
season just what is most likely to give him trouble or anticipate
just when it is going to occur. In the case of apples, for example, a
spraying program has been developed which, if carefully applied, will
result in freedom from fruit worms and apple scab, and this spray-
ing program is used by commercial orchardists year after year re-
gardless of the varying outlook as one season follows another.
Unfortunately, the measures which have been developed to protect
cranberries against losses from pests are not of this nature. The
sources of trouble vary from season to season and protective meas-
