4.5.6 EFFECTIVENESS AND NOZZLE ORIENTATION

Always guarantee the presence of nozzles on the machine able to produce a fine spray
and homogeneous if kept in the best conditions.
The orientation of the flow of the mixture inside of the air flow is achieved by rotating the
nozzle to get always a complete penetration of liquid in the canopy (see section 4.3.1).
4.5.7 EFFECTIVENESS AND AIR VOLUME ORIENTATION
The machine must have an air flow delivered on the area to be treated.
It is also necessary that the air goes through the canopy without removing the product
already settled.
It is suggested to sway the leaves of the outside furthest of the canopy. If the leaves are
closed, the air flow is insufficient, if the leaves are arranged in a flag, the air flow is too
high and there is too much chemical dispersion.

MIXING

The mixing of the active ingredient can be made using a shakers before and during
treatment. A good mixing and agitation mean successful delivery on culture. It is
recommended the use of premixer for powders and liquids.
Caution: wear gloves and protection mask!
The mixing can be done with:
LID's Premixer (optional):
Open the lid and put the chemical powder in the filter bag, close the lid and
turn the knob counterclockwise until the total dust disposal.
Feed the stirrer for 15 minutes at maximum pressure (for 30 to 50 Bar) or
operate the pump at 500 rpm with the pressure regulator on exhaust position
for at least 10 minutes (for small capacity machines).
Premixer for powders and liquids with washing -jars (optional):
Remove cover
Open the faucet with a pressure not exceeding 3-4 Bars
Enter the jar into the hopper and washing tube inside the jar.
Press the same jar on the tube until thoroughly washing
If the washing -jars is not supplied with clean water, it requires an additional
rinsing with clean water. (Rinsing liquids must be filled in the tank to be
delivered in the field).
In case of momentary interruptions of spray work do not interrupt the agitation of the
mixture until the restart of spray work
Check the intake filter cartridge and shake the mixture remained in the tank for at least 10
minutes in the case of prolonged interruption of treatment.
