Temperature inversions affect pesticide applications

by Tyler Williams, Extension Educator

Temperature inversions are a common occurrence in Nebraska and influence pesticide applications and controlled burns. A typical inversion will begin to form when the surface starts cooling, which is often 1–3 hours before sunset. Inversions below five feet above the surface — or in valleys — may occur earlier. The inversion will typically persist and strengthen overnight where maximum intensity will occur shortly after sunrise, often lasting 1–2 hours after sunrise. Evening inversions pose a greater risk for pesticide movement than morning inversions due to this overnight persistence. Learn more, read Temperature inversions affect pesticide applications.
