NOZZLE TYPES IN FARMING
19.1.1
NOZZLE TYPES WITH A FLAT JET
Figure 19.1
This kind of nozzles is principally used for spraying with
herbicides, insecticides and fungicides. The insecticide is precisely
distributed along the whole working range of the nozzle. At lower
pressure, the drops are bigger and less sensitive to wind and vice-
versa. The recommended working height is 0.5 meter above the
crop.
For reasons of correct overlapping of the jets, the nozzle adjustment is very important. The nozzles
must be offset for 5°-10°according to the equipment
.
Figure 19.2
Recommended working pressure:
•
Herbicides: 1.5-3 bar
•
Fungicides: 3 -5 bar
•
Insecticides: 3 -5 bar
19.1.2
WHIRL NOZZLES
The jet of such nozzles in formed like a rotating cone. They consist of a whirling and a spraying part.
Spraying parameter settings should be such that the overlap of jets between the two nozzles is
minimal.
The main characteristic of these nozzles are smaller drops, the insecticide distribution is worse. They
are suitable for spraying with fungicides and insecticides.

Recommended working pressure: 2 - 10 bar
