h
the butterflies will lay their eggs. This piece is to be then plowed
under.
3. Hand pick the worms from the plants after they are set out, for the
first one or two hoeings, or until the worms become very numerous.
4. Spray with kerosene emulsion, made by using two gallons of kerosene,
one-half pound of common or whale oil soap, and one gallon of water.
Dissolve the soap in the water, and add it, boiling hot, to the
kerosene; then churn, while at least warm, for five or ten minutes, by
means of a force pump and spraying nozzle, until the mixture loses its
oiliness and becomes like butter. When used, dilute one part of the
emulsion with about fifteen of water, and spray it upon the plants by
means of a force pump and spraying nozzle. This emulsion is also
excellent for the cabbage louse and many other insects. In the report of
the United States Department of Agriculture for 1883 may be found a
description and figure of a suitable spraying apparatus.
5. Pyrethrum, one ounce to four gallons of water; or, better still,
mixed one part with about twenty parts of flour and applied while the
dew is on, is an effectual remedy.
6. Hot water, at 130 deg. Fah., will kill the cabbage worms and not injure
the leaves. Boiling water, placed in sprinkling cans and taken directly
to the field, will be about the right temperature by the time it can be
applied. Experiments with a few plants may be needed to enable one to
get just the right temperature to kill the worms and not injure the
plants.
7. Take half a pound of London purple to thirty pounds of finely
pulverized dust of any kind, the finer and drier the better; mix
thoroughly, passing all through a meal sieve. Dash a small pinch into
the heart of the plant, so that it will settle as dust on all the
leaves. Repeat after every rain. Half a pound will serve for one
application over forty acres. Store any that remains in a very dry place
until again wanted.
8. Professor Gillette, of Colorado, finds the best remedy to be Paris
green, thoroughly mixed, one ounce with six pounds of flour, and dusted
lightly over the plants while the dew is on.
FUNGUS DISEASES.
There are several parasitic fungi which are more or less destructive to
the cauliflower at different stages of its growth. The principal
diseases of the cauliflower due to fungi are the following:
STEM ROT.--This is an old disease, which attacks the
cauliflower, cabbage and other vegetables in wet seasons. It
