slip down into the ground between
the plants and the lime.
A mixture consisting of two
pounds of glue dissolved in one gal
Ion of water, and this mixed with a
halt pound of glue has been used sue
cessfully against the cabbage maggot
A handful of the material is placed
around each plant q day or two after
setting. 1t forms a covering three or
four inches in diameter on the
ground and closely around the stem,
through which the maggot when
Matched from the egg is unable to
make its way to the plant tissues be-
low the surface. 1t is stated that the
mass is very resistant to weather.
ana remains intact so long as there
IS any danger of the maggot attack.
If for any reason the maggots
are not prevented from getting a
toothold in the plants, measures
should be taken to destroy them as
soon as their presence is noted. AS
a killing agent, carbon disulphide
is very effective, but its use is prac-
tically limited to the maggot on
cabbage and cauliflower. Make a
small hole in the ground two or
three inches from the plant, and ex-
tending obliquely down as far as the
roots. Pour or inject into it a spoon
full of the liquid. Close the hole by
pressing the earth over 1t, and the
fumes permeate through the soil,
coming in contact with the maggots
and killing them.
"Carbolic emulsion is perhaps the
most effective of all the destructive
agents, its use depending, however.
upon timely, frequent. and through
appli cations Dissolve one pound of
soap in one gallon of boiling water,
to this add one pint of crude car,
bolic acid, and churn thoroughly
with pump until a good, creamy
| emulsion is obtained. For use di-
lutte one part of the emulsion with
thirty parts of water and apply
thoroughly around the plants, from
four to six ounces to each. The OBJ
ject is to get it down to the roots
and into actual contact with the
maggOts feeding upon them. The ap-
plication should begin as soon as the
presence of the maggots is noted, or
better still, as soon as the eggs are
observed on the plants. Make the
first two applications four or five
days apart, and later once a week
for a month. This material can be
used against the maggots on radishes
and onions by making thorough APP
pliCations along the rows. The work
should be done SO as to kill the
young maggots as they emerge from
the egg and before they have a
chance to protect themselves in the
plant tissues, as when we'll grown
they are quite resistant to the emul-
sion. e
'Hellebore decoction is made y
sleeping two ounces of powdered
hellebore in a quart or two of boil
ing water for half an hour, stirring
occasi onally so as to assist in the
extraction of the poison. Then dilute
SO as to make one gallon of liquid.
Apply this in the same way and under
the same conditions as recommended
for the carbolic acid emulsion. 1t
should not be applied as a spray, but
through a spout in quantity suffi-
cient to soak around the plant to
the roots. say from four to six
plant, and proportionately along the
radish, turnip, or onion rows.
THE hand method consists of
taking the plants carefully as soon
as they show evidence of maggot at
tack, with all the earth around the
roots, so as to get all the insects.
and ASKING the roots in a solution of
soap or hellebore, and removing the
maggots, after which the plants are
reset. This is heroic treatment, but
certainly very effective. 1t is most
feasible on cabbage and cauliflower
plants.
I'm onion fields it not frequently
happens that there is a infestation
of only a few plants here and there,
and that the farmer will not feel
like making a general treatment.
Pull up all infested onions, put them
in pail and when all the infested
plants are in it, drench them with
kerosene. When in the onion field it
is well to keep constantly in hand a
tin pail and a trOwel, keeping a con-
slant lookout for infested onions.
By this method, and the fertilizer ap-
plication when there is danger of a
more general attack, many onion
| growers have been able to keep their
| onion fields comnaratiVply free of
