close watch should be kept for the
insect. Avoid planting such crons op
ground infested the previous season
and follow such infested plots with
something other than onions or
crueiferae tplants with four petals
arranged like the arms of a cross
as mustard, radish and turnlp)
When cabbage and cauliflower
plants are set out the soil should be
tightly pressed around the stem of
the plant at the surface, and the soil
ltself should be pressed down smooth
and firmly. The newly Matched mag
got is very feeble and if it fails IN
get under cover promptly it is killed
by the sun or falls a victim to some
OF the prowling, predatory insects
that are continually on the lookout
for food.
On heavy soils this in itself af-
1ords a large measure of protection
and plants on such soils are not so
much attacked. On lighter, sandy
soils it will be less useful. bur will
add to the difficulties of the maggot
in establishing itself.
When laid on the ground the
eggs do not hatch readily after they
have been disturbed, and when they
are observed the earth around the
plants should be scraped toward the
center of the rows. This will cause
some of the eggs to be exposed and
dry up, or the young maggots from
those that hatch will not be able to
find food within their reach.
Some of the eggs are deposited
on the plants, so the latter should
be rubbed so as to destroy any that
may be on them.
By the use of repellant sub
stances it is often possible to make
such that the maggots will be un-
able to get feeding places after
they hatch. Tarred paper cards, con-
sisting of round, square or other
wise shaped pieces of cardboard
coated with tar and fitted snugly
around the stem of the plant
have been used to good advantage.
They should be placed fiat on the
ground SO that the fly cannot get
under them, in which case she will
be forced to lay her eggs either on
the cards or on the dirt beyond. If
laid on the dirt, the maggots when
Matched Will be unable to reach the
plant, and if on the card, they will
inevitably dry up before the larvae
develop. Such larvae as may develop
will be unable to penetrate the tough
skin of the stem above the surface.
The cards can be easily and cheaply
made at odd times, and can be read
lily applied when setting the plants.
"Carbolic acid and lime is another
repellant. Stake the lime to a thin
cream, using three pints to a gallon
ofwater, and to this add a tablespoon
full of G"ude carboliC acid Apply
along the rows, getting it we'll
around the plants SO that the SUI
face will be coated to the plants.
This may be used on all kinds of
plants, subject to maggot attack,
forming a covering through which
the young maggots are unable to
penetrate to reach their food. The
young plants seem to find no diff
Guilty in growing through the lime
coating.
Kerosene and sand is a repellant
that has been successfully used To
a pail of dry sand use half pint of
kerosene, mixing it thoroughly. Make
the first application as soon as the
plants are above ground, following
in five days with second, and later,
apply at intervals of a week. The
flies do not readily deposit their eggs
in this mixture, and if any of the
maggots come in contact with the
kerosene they will be killed. Care
must be taken not to have lore ker-
osene than is recommended, nor to
pile too much of the sand around the
plants at one time.
Powdered tobacco used as a pre-
ventive appears to protest treated
plants to a certain extent, even
though applied late. Frequent and
through application is necessary.
The fly does not care to deposit its
egg on the tobacco and, if so, the
tobacco, if the covering is thorough,
is likely to kill the maggot, especial
ly if it is wet The tobacco is a fer
tilizer of value, so great that it's ap-
plication would be of advantage suf-
ficiently great to pay for its use. 1t
should be as finely ground as is OBJ
tainable.
Powered white hellebore may be
applied in the same manner as the
