The Mesonet Spray Tool reports live weather conditions for pesticide applicators.
Inversions and high winds are the most important weather conditions to assess when 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. An email can be sent for recordkeeping.
The Mesonet Spray Tool is supported by the South Dakota Soybean Research & Promotion Council.
