What fungicide would be safe to use on a Cox's Orange Pippin apple tree? Cheers

I can't recommend a clean up spray on your apple tree in winter as Lime Sulfur is not suitable for spraying Cox's Orange Pippin apples. However Leaf Curl Copper Fungicide can be used to control black spot and bitter rot on apples while Liquid Copper is registered to control black spot on apples. These sprays are applied at green tip stage. Follow the directions on the label for dilution rates.
