Choosing Nozzle Type; Influence Of Climatic Conditions - Jacto PJ-16 Manuel D'opérateur

NOTE: For the volume in liters per bushel (L / alk), simply multiply
the value obtained in liters per hectare (L / ha) by 2.42.
WARNING!
Wear a protective clothes to do the mainte-
nance and parts replacement.

4.3. Choosing nozzle type

Seven main nozzle designs are used on knapsack sprayers. Each
nozzle design is available in a range of sizes to optimize the use
of product to be applied. The nozzle choice will be based on the
agrochemical type to be used and the droplet size recommend-
ed (table):
NOTE: This sprayer is packaged with Blue Adjustable Cone noz-
zle fitted in the lance. Other nozzles mentioned in this manual
are optional, so they do not accompany this sprayer.

4.4. Influence of climatic conditions

During application, some factors may determine the interrup-
tion of the spraying. Wind currents, for example, can drag drops
to a greater or lesser distance in terms of its size or weight. The
temperature and especially the relative humidity contribute to
the rapid evaporation of the droplets.
The ideal conditions for spraying are:
• Relative humidity: minimum 50%;
• Wind speed: 3-10 km / h;
