overlap and complete cover-
age of the surface being
sprayed. For eighty degree
flat fan spray tips eighteen
inches from boom to ground
surface will give good cover-
age. ,
You can also measure the
wet area under one nozzle.
The wet area should be fifty
-per cent widerthan the
distance between the nozzles
on the boom.
The boomshould remain
parallel to the ground and
held rigid: to minimize bounc-
ing and improper coverage of
the soil.
Nozzle delivery can be
checked with a calibration
bottle. Run the sprayer at
operating pressure and col-
lect the material from one
nozzle. Record the number of
seconds .to partially fill 'a
bottle. Record the amount
from each nozzle if the
amount varies more than five
per cent. Calibration bottles
are . available from dealers
and .givethe rate in litres/
hectare . and gallons/acre.'
With all pesticide recom-
mendations now made in
metric it is important to know
how many ' litres/hectare
yourequipment sprays.
Dietz discussed the pro-
cedure which should •be
followed for agood incorpor-
ating job. Tandem discs can
be used, cutting four to six
inches deep at four., to six
Miles per hour.
Power driven equipm.entat
a depth of two to three inches
can also be used. A danish-
type cultivator with tires on
six to eight inch centres set
four inches deep in the soil
will incorporate well•if driven
at six to eight miles per hour,
In all of these methods the
equipment being- used
should be fitted with a
levelling device.
A question was asked as to
whether land should be
worked before incorporation.
Dietz felt that land shouldbe
worked once before incorpor-
ation to break up lumpsand
get better incorporation ` of
herbicide. "You don't want
to incorporate herbicides too
deep," said Dietz, "or they
won't be effective."'
After spraying mainten-
ance is important for proper
functioning of the sprayer in
the next season. Drain the
sprayer completely and flush
the tank. Clean all . equip-
ment with household am-
monia and. rinseseveral
times with water.
Make sure . the pump,
control valves and lines are
completely drained of fluid.
Blow .out, clean, and dry
all orfices including the tips.
Mo not use :a metal brush. If
tips are plugged use a fine
soft brush or tooth pick to
clean them. ,Water rinse all
parts and dry tips before
storing.
Pour lubricating fluid or
antifreeze in the pump or
remove and store in a dry
place., Turn the , pump over
several times in storing with.
light oil or antifreeze in the
chamber. Seal the sprayer
and all hose bearings to
prevent entry of dirt or
rodents.
Relieve all pressure on
gauges and pressure regulat-
ors. Grease and oil (chains if
any) and prevent rust.
' Touch up scratch marks or
chemical damage with paint.
Store the sprayer inside and •
make sure that you do not
store or place anything on
the tank as you may distort
the shape.
If you are storing leftover
spray fluid or . chemicals,
make sure it is notaccessible
to children, livestock or pets.
To do an effective job of
spraying Dietz recommended
not to spray while . turning
corners: The inside nozzles
overlap and the outside noz-
zles go too fast, failing to
deliver the proper amoung of
chemical on the corner.
Make square corners,"
he said, '"by , stopping the
boom distance away from the
.fence. Take the time to back
into corners and make sure
that all nozzles zzles are working -
then spry."
This spring consider call-
brating your sprayer to de-
termine the litres per hectare
that it sprays. You can then
determine how much pesti-
cide
esti cide to add to a tank full of
water to achieve the proper
amount. of chemical peOect-
are which you require to
control a pest onyour farm..
