Special hints for spraying operation
Important!
x Check your field sprayer by carrying out a calibration
x before the beginning of any seasonal operation.
x
in case of deviations between the actual spray pressure
and the spray pressure required according to the spray
rate chart.
x Before commencing the spraying operation accurately de-
termine the required spray rate following the instructions of
the plant protective agent manufacturer (please refer to
chapter "Preparing the spray mixture", page 165).
x Before starting the spraying
operation, please enter the
necessary spray rate (required rate) into
.
The
gives a fault message and an
audible alarm signal if the necessary spray rate is not
maintained during the spraying operation.
x Accurately maintain necessary spray rate [l/ha] during the
spraying operation,
x in order to achieve the optimum success of your plant
protective measures.
x in order to avoid unnecessary harm to the environment.
x Prior to the spraying operation choose the required nozzle
type from the spray rate chart - considering
x the intended operational speed,
x the required spray rate and
x the required spraying characteristics (fine, medium or
coarse droplets) for the crop protection agent used for
the plant protective measure used.
Please refer to chapter "Spray rate charts for flat fan-,
anti drift-, injector- and airmix-nozzles", page 218.
x Prior to the spraying operation choose the necessary
size from the spray rate chart – considering
x the intended operational speed,
x the required spray rate and
x the desired spraying pressure.
Please refer to chapter "Spray rate charts for flat fan-,
anti drift-, injector- and airmix-nozzles", page 220.
x Choose a slow forward speed and a low spray pressure to
avoid drifting loss.
Please refer to chapter "Spray rate charts for flat fan-, anti
drift-, injector- and airmix-nozzles", page 220.
x Take additional measures for drift reduction at wind speeds
of 3 m/s (please refer to chapter "Measures for drifting
reduction", page 195)!
x An even lateral distribution will only be achieved with the
swing compensation unlocked.
x Discontinue the spraying operation at average wind speeds
of above 5 m/sec. (leaves and thin branches are moving).
