    It is important to measure variations in conditions within a field to prevent farmers from applying the same amount of fertilizer over an entire agricultural field. Weather conditions such as wind, temperature, relative humidity and precipitation have direct impact on the effectiveness of spraying applications and the influence waste potential due to run-off and drift.

    Relative Humidity and Temperature

    Know your relative humidity and temperature – avoid unnecessary and costly trips to the field.

    • Spray when temperatures are low and relative humidity is high. In general, do not spray when relative humidity is less than 40% and air temperature is above 25°C. This reduces the chance of drift due to temperature inversions or evaporation. It also increases target deposition and coverage.
    • Hot and dry conditions increase drift because droplets rapidly evaporate and become fine droplets, vapour or particles of concentrated pesticide.
    • Optimum spraying conditions are early mornings following overcast nights. However, the best time to spray to avoid disrupting bee activity is evening or at night.

    Set Your Crops Up for Success

    Weather conditions are an important factor that you should consider when making the decision to head to the field. With all the pressure to get started planting, spraying or harvesting, it is important to take the time to ensure you are setting your crop up for success.
