Influence Of Climatic Conditions; Optional Accessories For Manual Knapsack Sprayers - Jacto XP-12 Manual Del Operador

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;
• Temperature below 30 C.
These limits should be considered according to technology
application that will be used, adopting the safest class drops
within the boundaries of each situation.
