Recommended duty limits for LU, AD and
ID/IDTA/IDK/IDKN/IDKT flat fan nozzles as a
function of wind speed:
Rule of thumb:
The higher the wind speed, the larger the nozzle size
in combination with minimal pressure is
recommended. The day curve of wind speeds should
be considered when spray application is planned.
Typically, the lowest wind can be expected in the
evening, overnight and early in the morning.
Delta T
Delta T is becoming one of the most important
standard indicators for acceptable spray conditions
referring to evaporation rate and droplet lifetime. It is
the agricultural term for wet bulb depression and
combines temperature and relative humidity. When
delta T is high, the evaporative potential is high and
droplet survival is lowered for smaller droplets. When
applying pesticides, Delta T should ideally be between
2 and 8 and not greater than 10 for coarse droplet
spray applications such as with ID/IDTA and
IDK/IDKN/IDKT nozzles.
