Air temps at 36F and Enviroweather dew point at 37F. Could I have sprayed a fungicide without fear of causing frost damage? Would this small amout of water caused a drop in temperatures similar to what would happen if I turned on frost protection sprinklers?
Yes the spray would have dropped the temperature but not enough to cause injury.
The temperature drop from 30-50 gallons of water evaporating would not have been enough to drop the temperature in the field 8 degrees
