Fig. 22
The nozzles used have the following positions:
-90 degrees / straight down
Stop
0 degrees / horizontal
for spraying before blossoming
15 degrees / upward
not used
20 degrees / upward
for spraying after blossoming
90 degrees / straight up
Stop
The correct setting of the nozzles is facilitated by a noticeable
click when turning.
For all spraying, make sure that the center of the fan units is
aligned to the center of the plants, so that the distances between
the nozzles and the plants are the same.
For bud burst spraying, a narrow fan unit can be used, which has
a positive effect on the return quantity.
The spray cones should overlap on the foliage wall in order to
achieve optimum distribution.
If the fan unit wall is too close to the foliage wall, the spray cones
may no longer overlap and there will be areas in the foliage wall
that receive no spray.
