cedar apple rust
Hello, three years ago we planted two varieties of apple trees which we thought were resistant to most diseases - Liberty and I think Goldrush. Well we finally have apples...but they and the leaves have cedar apple rust! Is there anything we can do NOW to save the leaves and this crop of apples? I understand that in future years we should apply a dormant oil in early spring.
Those apples are scab-resistant, not totally "disease" resistant. I suspect the Goldrush has more rust. Nothing you can do now, you need to spray fungicides next spring and/or remove the alternate juniper host. For more information, please see:
