Air Temperature Inversions: Causes, Characteristics and Potential Effects on Pesticide Spray Drift

Pesticide spray drift always has been a costly and frustrating problem for applicators. It's particularly frustrating because some of the seemingly best weather conditions for pesticide application are often the worst. That is because those conditions are caused by air temperature inversions. Air temperature inversions provide near-perfect conditions for tiny, aerosol-size droplets to drift away from their targets.
