Poisoning.
In Idaho clover and alfalfa fields.
spraying with a solution of sodium ar
semitic has proved very successful.
This does not apply very strongly to
Power county conditions. Here we
u use In our grain fields, the poison
bran mash. This is made up accord
ing to the following formula:
1. Bran, as pounds.
2. Paris green or white arsenic, /
pound.
8. Oranges or lemons, s, Tor Lemon
extract)
4. Cheap syrup or molasses, 2
quarts.
8. Water, 3 gallons.
The bran and poison should be plac-
ed in a tub and mixed dry. Then an
oragne ade or lemonade should be
made by grating OF chopping up the
lemons or oranges using the juice, pulp
and peel. This should be poured into
the three gallons Of water and the
syrup or molalsses added while being
stirred. One ounce OF lemon extract
oragnes or lemons. Lemon extract
has a o penetrating and lasting
odor than the fresh fruit and has the
added advantage of being cheaper.
The oragneade or Lemonade should
then be poured over the dry bran and
poison mixture, this being stirred UNI
til thoroughly dampened and a crum-
my mash obtained. 1t is undesirable
to have the mash mushy or sloppy.
Get 1t just crummy enough so that 1t
may be broad casted in the field with
ease. e
This Is sufficient for from 3 to 5
acres and should be applied very ear
ly In the morning before the hoppers
become active enough to leave the
grass and brush near the ground to
which they retire for the night. They
Will then commence feeding for the
day on the bran mash which they at
tack very greedily while fresh. This
mash is good for about one day.
Grasshoppers will not feed on stale
bait and the poison mash should be
prepared every day just using. Look
for results on the third day. 1t is
most effective with young hoppers.
The live hoppers will eat the dead
ones and in this way the poison does
double duty. The formula for the
spray may be secured upon application
from the county agent or from any OF
the county druggists to whom have
been given bulletins with the formula.
Cultivation for Egg Destruction.
Any system of poisoning, however,
Is necessarily expensive and not CON-
pletely effective 80 W. have had to
resort to the destruction of eggs by
cultivation. The female grassnopper
deposits eggs in curved cylindrical
capsules, about half an inch to an
inch below the ground from the time
she reaches maturity to freezing
weather. This mass of yellowish
brown eggs are firmly cemented to-
gether and entirely covered with ad
herring earth. The eggs are laid pre-
ferably in firm soil In a well drained
location. Abandoned fields, turn rows
the undisturbed strips under fences
along neglected roadways. and on
banks of i~rrigating bitches, and buf'
falo sod along the edges of infested
fields are favorable places for egg
laying.
The eggs hatch about the time OF the
last spring frosts, when warm wealth
err has come. The young grasshopperi
push up to the surface and feed OF
the nearest green vegetation. At frs
they are almost white but darker
quickly in the light. AS they grow
larger the skins of the grasshopperi
stretch and break and the young In
sect escapes. This nothing process
occurs five times before the grass
hoppers are fully grown.
The following control measures de
signed to keep the eggs from hatch
ing are based on practice which prov
ed most effective In Kansas durtnl
the bad years.
II spring blowing Is necessary. plo'
at least six inches deep so as to turl
the eggs far enough under that tn
grasshoppers cannot escape to tn
surface when hatched. This shout
be finished before the middle OF April
If blowing is not necessary, stir tn
soil about two inches deep with
disc or drag. Harrow very late IN tn
fall or before March I. This break
up the capsules and exposes the egg
to freezing and insect enemies an
diseases. In weedy or sody fields O
alfalfa, the disc or spring tooth Is re
quired.
