Of SurfACe TemPerATure SPrAy OPerATiOnS in cooling night conditions airborne pesticides can concentrate near the surface and unpredictable winds can move droplets away from the target... During surface temperature inversions, air near the ground lacks turbulence... SOurCe GrAeme TePPer under a surface temperature inversion: air movement is much less turbulent so the air does not mix in the same way as during the day; airborne droplets can remain concentrated in the inversion layer for long periods of time; the direction and distance pesticides movement is very hard to predict; the movement of airborne droplets will vary depending on the landscape; and droplets or their remnants can move in different ways (figure 3)...

GRDC is supporting research to better understand inversion conditions and to provide resources to anticipate and recognize inversion conditions... Temperature inversions suppress vertical motion of the atmosphere and thereby cause concentration rather than dispersion of pesticide droplets, vapour or particulate matter that remain airborne after application... The risk of spraying when inversions exist There is real potential for small droplets, vapour and particulate matter to drift for long distances at high enough concentrations to contaminate and damage sensitive crops and the environment...
