Web Worms In Alfalfa.

More or less needless confusion has
arisen this summer concerning inc
, control Of the web worm that mas
| ILcen generally prevalent during the
Halter part of August, and the flrst
part of September
This worm generally occurs about
three times during the summer me
| first brood appears on careless weed
land similar plants, but Is not gener-
lally noticed on alfalfa. The second
brood occurs to some extent on cotton
and alfalfa. The third brood gener-
Ially damages alfalfa to a considerable
extent In some localities unless II Is
promptly controlled.
There Is one indirect and two indi-
rect methods for controlling the pest
From now until the alfalfa begins to
grow In the spring Is the time to prac-
tce the Indirect method, which Is by
lrenovating such alfalfa fields as the
renovator can be used on without In
turing the plants. The fall plowing
under of all grasses and weeds grow
ing in the cultivated fields, and the
burning of weeds and grasses which
cannot be otherwise destroyed In the
lout-of-the way corners and fence rows
This win destroy their winter quarters
so that they cannot Withstand the In
lClemency of the winter.
one direct method Of control Is by
moving the alfalfa If II Is Of sufficient
growth to be made into hay when the
worms begin to deyOur IT, When
placed on "A dry ration they perish. The
hay will not be Injured for market or
feeding purposes by their presence.
The other direct method is by the
application Of Paris green Judgment
should, OF course, be used In the APP
Iplication Of an arsenical Lead arsen-
ate should not be used, on account OF
! its adhesive qualities. stock eating the
hay would be poisoned, If good rain
| follows the application Of Paris green
before the hay is cut, no injury will
result, since the poison will be wash
ed from the plants to such an extent
that 1t will be Of no consequence as far
as the hay Is concerned II the alfalfa
is young and note large enough for
hay the use Of Paris green for CONTROL
ing the web worm Is superior to any
other remedy.
Paris green should be diluted at the
rate of about one pound to ten OF lime
| for ordinary applications II the sou
needs lime, however. there would be
no objection to using any amount Of II,
so far as the effects OF the Paris green
lis concerned. II the latter is equally
distributed in 1t 50 that It can be
evenly applied.
About one pound OF Paris green
per acre should be used on alfalfa
which is less than three or four inches
Thigh, and a pound and a half to two
pounds on 1t when taller
A dry application Is the best form
In which 10 use the poison for this
purpose The pole and bag method Of
distributing it Is not perfect and should
he used only In case Of extreme nee
essity. The proper method Is by
means Of duster, which can be ar
ranged by any one having a little In
genuty and the proper tools A small
tanning mill similar to that used In
! portable blacksmith fOrges can be
fused. This can be made OF tin, and
gearing from old machinery, and ar
ranged on a spring wagon, cultivator,
or other light farm machinery. In such
a way as to do the work perfectly.
Care must be used In gauging the
amount OF poison used, For this an
' adjustable feed valve should be used
between the poison vessel and the dis
! tributing bpouts leading while out
/ from II for blowing the material broad
cast while the machine is being driven
through the field,
Regular dusng machines, manu-
, factured especially for making such
applications, are now on the market
at a nominal cost In case one has
an orchard spraying machine with a
field of attachment for applying M
: ulds the Prais green could be mixed
with water and lime and applied al
about The same rat. p-r acre.
