Spraying - Gloria 172 RTG Mode D'emploi

Sample computation for checking
and determining dosage of spray
compound
Bases:
Spraying pressure 1.5 bar
Nozzle
Spraying height
Dosage
This means:
Quantity required
Spraying width
Angle of spray
Quantity of spray compound
per m 2 0.06 l = 600 l/ha
(see pesticide manufac-
turer's instructions)
To mix 1 l spray compound:
1l water + 5 ml compound
(5 ml = 0.5% of 1 litre)
With a spraying width of 50 cm, a length
of 2 m equals a sprayed area of 1 m
Speed of spraying:

The figures on which this sample com-
putation of the dosage and the quantity
of spray compound required per m
based have been assumed for that pur-
pose.
When using the sample computation,
the figures given by the manufacturer of
the respective spray compound must be
used.
If other nozzles are used, the appropriate
technical data must be taken from the
separate sheet 974 717**
(Optional Accessories and Nozzle
Table) and used in the computation.

Spraying

G To obtain as even a spray pressure
and as long a spray cycle as possi-
ble, set the pressure regulator on the
quick close valve at the minimum
permissible pressure (e.g. 1.5 bar for
nozzle GH 49-55).
G To start the spraying process push
the operating lever on the quick
close valve down. Releasing the op-
erating lever will stop the spraying
process immediately.
G If the pressure in the tank falls below
the minimum permissible pressure,
work the pump a little to ensure an
even spray. The optimum spraying
