Farm Table says:

Provides some very useful visual representation of inversion.

The key takeaway points are:

  • Where surface temperature inversion conditions exist it is unsafe for spraying due to the potential for spray drift.
  • Spray applied at dawn, dusk and during the night is likely to be affected by a surface temperature inversion.
  • During surface temperature inversions, air near the ground lacks turbulence. This can lead to airborne pesticides remaining at high concentrations in the air at or near the surface.
  • The direction and distance that pesticides can move in the air close to the ground is very hard to predict when surface inversions exist.
