Use accurate forecast information to help plan spraying activities.

Always measure and record weather parameters at the site of the application before, during and on completion of spraying operations.

Wind direction and wind speed are critical for assessing suitable conditions and potential risks.

Temperature and humidity (or Delta T values) can assist in understanding evaporation and spray-drift risk, but can also identify potential impacts on efficacy.

Always follow the label directions for appropriate conditions for spraying, including downwind buffers or no-spray zones that are related to wind speed.

Consider what weather-monitoring equipment will best suit your enterprise.

DO NOT spray under hazardous inversion conditions. While surface temperature inversion conditions can occur at any time, they are present most nights from around 1-2 hours before sundown until about 1 hour after sunrise. To understand if an inversion is hazardous or not, advanced meteorological weather stations will be required and these must be located within reasonable proximity to, and without substantial changes in terrain between the weather station and the application location.
