Can anyone tell me how to control cedar apple rust on my trees?
And also, does it affect just the fruit? Or also the tree? :confused:
Thanks a bundle!

Cedar trees are hosts to the cedar apple rust. You can spot it in the spring as small masses of orange stuff hanging here and there. You didn't say what kind of trees you are having trouble with but apples are the main one. The spring is when the rust is most active - in damp, cool weather. I know of no real effective control (short of cutting down all the cedars within infection distance), except that some apple trees are more rust resistant than others. Liberty is one of those. Stark Bro. nursery in Missouri stocks some of the rust resistant varieties and perhaps other nursery's as well.

Just how far IS infection distance? Seems to me I've seen the orange fungus in my area (Missouri Ozarks) Are there non-dangerous look-alikes? I was planning to plant apple trees next spring...

Cedar-apple rust infection distance can be from 1/2 to 2 miles, depending upon the terrain and prevailing wind direction in the spring. Apple orchardists seek to eradicate the host plants, mainly juniper, or red cedars, within as many miles as they can. Fungicides are available to help control the rust on apple trees but must be sprayed on frequently, and are rather expensive, not to mention unhealthy to humans. The best bet is irradication, if that is an option, which usually it isn't because one cannot simply cut down a neighbor's cedar tree. Next best bet is to plant rust resistant types. You can read all about cedar-apple rust by using your search engine, type in cedar-apple rust. I know the university of Ohio has a good, informative site on this subject, with color pictures, etc.

I know this is an old thread, but I have this same problem on my mayhaw trees. From the research I've done this is the same as Quince Rust. My mayhaw trees are usually loaded with fruit, but so discussing looking when ripe from being so distorted. This year as bad as I hate to use chemicals on them I am going to use Daconil (xxxx) (some numbers behind the name I can't recall right now) as recommeded when the blooms just start to open up, as recommended. I know the research says to remove/cut down all cedar trees within a mile radius, which would be impossible for me to do. Neighbors could get a ill about that. lol. If I don't see any results this time around, then I'll probably remove my trees and plant something less aggravating. I have dealt with this problem for a few years now. Enough is enough. trudyjean

This is an old thread, but for anyone who is interested, we grow only apples that are resistant... Liberty, winesap, Arkansas Black, and Startkrimson Delicious. Last I heard there were no yellow apples that were resistant.
