8.5 Spraying operation
8.5.1 Special notes for spraying
operation
¾
Check the crop protection sprayer by
volu-
metric measurement
•
before the start of the season.
•
in case of deviations between the actu-
ally displayed spraying pressure and the
spraying pressure required according to
the spraying table.
¾
Before starting spraying operation exactly de-
termine the necessary
application quantity
by using the instructions for use issued by the
crop protection agent manufacturer.
¾
Enter the required application quantity (nomi-
nal quantity) into the terminal before starting
spraying operation.
¾
Strictly adhere to the required application
quantity [l/ha] when spraying,
•
to achieve an optimal treatment success
with this crop protection measure.
•
to avoid unnecessary impact on the envi-
ronment.
¾
Choose the required
nozzle type
from the
spraying table before starting spraying – un-
der due consideration
•
of the intended travel speed.
•
of the required application quantity.
•
of the required atomizing characteristic
(fine, medium or large drops) of the crop
protection agent used for the crop protection
measure to be carried out.
•
of recommended distances.
¾
See also chapter "Nozzle selection".
¾
Choose the required
nozzle size
from the
spraying table before starting spraying – un-
der due consideration
•
of the intended travel speed.
•
of the required application quantity.
•
the planned spraying pressure.
¾
See also chapter "Nozzle selection"
¾
Choose a slow travel speed and a low spray-
ing pressure to prevent losses by windward
drifting!
¾
See also chapter "Nozzle selection"
¾
Apply additional measures for windward drift
reduction at wind speeds of 3 m/s.
¾
See chapter "Measures for windward drift
reduction".
¾
Refrain from treatments at average wind
speeds in excess of 5 m/s (leaves and small
twigs are moving).
¾
Switch spraying on and off only when driving
to avoid overdosing.
¾
Avoid overdosing caused by overlapping
•
in case of inaccurate joining passes from
one spraying track to the next and/or
•
when cornering at the headland with spray-
ing boom switched on!
¾
During spraying operation keep an eye on
the actual spraying mixture consumption in
relation to the treated area. In case of discrep-
ancies between the actual and the displayed
placing quantity calibrate the flow meter.
¾
Teach procedure must be carried out by
HORSCH service staff.
¾
In case of deviations between the actual and
the displayed distance calibrate the position
sensor (pulses per 100 m). This activity should
always be executed in the field.
¾
Teach procedure must be carried out by
HORSCH service staff.
¾
In case of weather related interruptions of
spraying operation it is mandatory to clean
filters, pump, fitting and spraying lines!
