Hello, my question is regarding my newly planted apple trees.
This fall I've just bought and planted two varieties of apples, 1 Golden Delicious and 1 Arkansas Black in our front lawn. The issue is that I know from our flowering crabapple tree in our backyard that our neighborhood has cedar apple rust disease. From my research, the Arkansas appears to be fairly resistant to the disease, but the Golden Delicious appears to be vulnerable.
I've been looking at various products and spraying information regarding protection against the disease. However, I've been unable to find info on when to start spraying, as in, how old and developed should the tree be? Since I've just planted the tree, and hopefully the trees will leaf out next spring, should I hold off spraying until the tree develops enough to bloom? Or should I start protecting the trees pre-emptively? I have not been able to find a good answer to this question.
I would also like to ask whether there is a product recommended for my region with known cedar apple rust, and whether non-chemical and organic control methods are even feasible with a vulnerable variety. I hope to avoid spraying for insects unless I can detect damage from pests, and perhaps shy away from the 6 application of anti-fungal schedule recommended by the Rutgers Extension office.
Thank you very much for taking your time to read my questions, and I hope you have a pleasant day.
