    Q
    Can I use Bonide Liquid Copper Fungicide as a systemic drench?
    After removing overgrown ornamental strawberries, I have discovered powdery mildew on the soil and remaining bark. I have removed as much of the back as possible, but wish to treat the soil before planting flowers.
    A

    Bonide Liquid Copper Fingicide Concentrate is not labeled to be used as a systemic drench. We would recommend using Agrisel BioPhos Pro Systemic Fungicide. It provides preventive and curative control of plant fungal diseases like Phytophthora, downy mildew, powdery mildew, greasy spot, late blight, and more. It is absorbed by the plants through its roots and foliage.  The residential/homeowner application instructions are below. 

    For preventative control of certain diseases in ornamentals. For soil drench, apply BIOPHOS™ PRO Fungicide at a 0.5% dilution. Mix 1/8 cup (2 tbsp) of BIOPHOS™ PRO Fungicide per gallon of water, and apply with a watering can or other device so as to wet the root zone.

    Q
    Can you use Bonide Liquid Copper Fungicide Concentrate on an ornamental cherry when the temperature is above 80?
    I have been told not to use this on my ornamental cherry for leaf spot when the temp is over 80 degrees - is this true? It now often gets near 90 degrees by the end of the day - so thought I could spray early in the day but do not want to cause problems.
    A

    Like most products, Bonide Liquid Copper Fungicide Concentrate should not be used in temperatures over 85 degrees. We usually recommend that you spray early in the morning or in the evening when the temperatures are usually cooler and the product will have time to dry before temperatures reach 85 or above. Spraying in the heat of the day will cause the foliage to burn.
