The Mesonet Spray Tool reports live weather conditions for pesticide applicators. It delivers live reports of actual measurements, not estimates or interpolations.
Inversions, high winds and low winds are the most important weather conditions to assess prior to spraying; their icons are stoplight color-coded () on the Spray Tool. Though not found in label requirements, Delta T is used by some applicators for nozzle selection and for drift and volatility avoidance.
The Mesonet Spray Tool is made possible in part by the South Dakota Soybean Research & Promotion Council
