Hand sprayers, in general, are not

applied to drive the insecticide un

cattle, or to plaster the material
against the wall, when barns are
being treated.

INSECTS ON RANGE CATTLE
Spray grubby area once with 400 to 600
P.S.I., then massage back with a dull
hoe and spray the same area again. See
Montana Extension Circular No. 222.
First spraving just prior to the emer
gence of the first grubs from the back.
Second spraying 50 to 60 days after the
first spraying.

powder (not liquid or powder made
from spraying liquid on a dust), 100
gallons water, and 1 pound of Tide or

Dipping is more effective than spray
ing. When spraying use 300 to 400 P.S.I.
and cover all parts of the animal's body
so as to wet the hair coat clear through
to the hide. See Montana Extension
Circular M-221.
Dip or Spray; 1/30 of 1% mixture of
gamma isomer of either crude Benzene
Hexachloride or Lindane (1 pound of
25% gamma isoifier wettable powder
to 100 gallons of water). Use wettable
powders only.

First spraying when first flies appear
in the early summer. Repeat sprayings

Look for ear ticks in the early spring
and spray when they are found. Ex

spraying and repeat treatment when
necessary.
Spray: Vz of 1% Toxaphene either
emulsion or wettable powder. (18

powder to 100 gallons of water.)
Cover tick^nfested area with the spray.

Spraying is supplemental to good sani
tation practices, it will not replace these
practices. See USDA, BE&PQ Leaflet
No. 283.
First spraying at the start of the fly
season and repeat every 2 to 3 weeks or
as often as is needed.
HOUSE AND HORN FLIES
Spray on Inside of Dairy Barn: % of
1% Lindané (16 pounds of 25% Lindane
wettable powder to 100 gallons of wa

feed boxes, watering equipment or milk
processing equipment.
Spray: Pyrenone mixed in accordance
with directions on the label (mix 1
part of an emulsion concentrate con
taining 1% of pyrethrins and 10% of
piperonyl butoxide with 9 parts of
water).
Spraying is usually ineffective unless
fresh manure, wet straw and moist
trashy areas are eliminated. See USDA,
BE&PQ Leaflet No, 283.
First spraying when the first flies ap

materials are wettable powders,
which means that sprayers equipped
with agitators in the spray tank are
desirable to keep chemicals in sus
pension. Knapsack sprayers, if used,
should be upended from time to
time to agitate the spray mixture.
In bam spraying, all feed, man
gers, watering cups and milking
equipment should be covered to pro
tect them from insecticide deposits.
A galion of spray per 500 square feet
will treat most barn surfaces to the
point of run-off. Bams should not be
sprayed within a week after white
washing since the insecticide will
npt remain effective on top of fresh
whitewash. The amount of deposit
visible on walls from the last spray
application is no indication that the
insecticide is still active, as this may
be merely the inert ingredients in
the wettable powder.
In general, it is felt that too many
dairymen concentrate on the interior
of the barn and neglect the exterior.
Keep dairy cows comfortable at
all times.
Plane Insurance
Ruling Modified
MONTANA FLYING farmers need
not carry liability insurance to spray
or dust their own cropland. This
modification of the Montana Aero
nautics commission ruling on aircraft
operators' insurance was made re
cently at the request of the Montana
Flying Farmers and Ranchers Assn.,
according to Louis G. True, secre
tary.
