Best fungicide for cedar apple rust?

Hi all,

I’ve got some cedar apple rust on an eastern red cedar and I was about to buy some mancozeb but I wanted to ask y’all what you think about different brands, etc.

What have y’all found to be the best brand, treatment, etc.? Thanks!

That is what I used last year when I had it pop up. I had no additional issues after treatment. I still had some leaf spotting on affected leaves, but no more leaves developed spots.
