| I did some searching on this site and I am pretty sure that this is CAR. I just planted 10 apple trees this year. and they have been growing great. However we had some very heavy rains for about 5 days straight and the leaves now have all of these spots on them.
Is this Cedar Apple Rust? About 10-15% of the leaves on every tree has them. If so can someone recommend an organic spray? I see Stark brothers sells a sulfur spray. Anyone use it? Any feedback? Thanks a bunch. |

| Yes this looks like CAR. There is no good organic spray and you are too late anyway. Spraying sulphur at the point of initial infection (roughly a month ago) next year will help. The primary organic cure involves a chain saw, chop down the nearby junipers. I had to remove a beautiful 50' juniper to deal with a CAR explosion. If your infection level is low it is really just a cosmetic issue. I have a few highly susceptible apples which would get totally spotted but still produced a good crop. Fruits will get it in a severe infection and at that point you have to chop down more junipers or remove apples that are not highly resistant. Scott |

| I don't even bother with it. Some apples aren't bothered by it much. I see some leaves out there on my trees with it and its no big deal. |

| Yep, that's it. It's usually more of a problem for the leaves than the fruits, which you don't have anyway this year. Just take this as a warning to do preventative spraying in the spring. |
