there is no need to collect and
kill the worms by hand. A good way to do this is to spray with Paris
green, in the usual way, a patch of young clover, then cut it and
scatter it in small bunches over the cauliflower field a day or two
before setting the plants. For the protection of a few plants in the
garden, an effectual preventive against cut worms is to surround the
stem with a cylinder of paper or tin. This need not touch the plant. One
should expect to lose some plants, however, by cut worms, and be
prepared with good plants to fill the vacancies.
CABBAGE MAGGOT (_Anthomya brassicae_, Bouche)--Dr. J. A.
Lintner, State Entomologist of New York, says of this insect: "This is
probably the most injurious species of the _Anthomyiidae_, as its
distribution is very extensive, both in Europe and America, and it has
shown at times such capacity for multiplication as to cause the entire
destruction of cabbage crops. It commences its attack upon the young
plants while yet in the seed-bed and continues to infest them, in
several successive broods, until they are taken up in the autumn. The
larvae operate by consuming the rootlets of young plants, and by
excoriating the surface and eating into the rind of older ones, or even
penetrating into the interior of the root. When they abound to the
extent of seriously burrowing the stalk the decay of the root frequently
follows in wet seasons, and entire fields are thus destroyed."
The same insect attacks the turnip, cauliflower, and probably other
plants. A closely related species is very injurious to the radish. The
presence of the insect most frequently becomes manifest upon the
cauliflower about two weeks after the plants are set out, and is
recognized by the plants ceasing to grow, and wilting or assuming a
bluish appearance. Such plants should be at once removed, together with
the earth immediately surrounding the root, and fresh plants which have
been held in reserve set in their places. The only satisfactory remedies
are preventive ones. The seed-bed should be composed of soil taken from
the woods, or at least from some place where no cabbages or similar
plants have been grown. But the most important precaution is to avoid
growing the crop year after year upon the same ground, especially after
the insect has made its appearance.
The following remedy, given by Francis Brill, in his pamphlet on
"Cauliflowers," is worthy of careful trial. Mr. Brill says: "The ravages
