Tom from Blountstown, Fl writes

What time of year do you spray pear trees for the spotted leaves using Southern AG Liquid Copper Fungicide?

Answer:

Southern AG Liquid Copper Fungicide is best applied to prevent diseases. This is usually on new growth before heat and humidity favor disease development. It should not be used in temperatures over 85 degrees. We usually recommend to spray early in the morning or in the evening when the temperatures are usually cooler. Spraying in the heat of the day will cause the foliage to burn.
