Cedar-Apple Rust (Juniper Rusts)

- čas přidán 8. 07. 2024
- The cedar rust diseases (Juniper spp.) stand out due to their conspicuous nature, and the fact the fungi that cause them complete their life cycles on two plant hosts - the juniper (cedar) and the apple (although pear, hawthorn, quince, serviceberry, and crabapple are other hosts). All potential host plants are commonly planted in the urban landscape, or are native to the Midwest. In Indiana, there are three common juniper rust diseases, Cedar-Apple Rust, Cedar-Hawthorn Rust, and Cedar-Quince Rust.
Regardless of the disease, these rust fungi have similar life cycles and cause similar symptoms in their hosts. In the spring, orange gelatinous horns develop from gray to brown colored fungal galls on the branches of infected junipers. These horns produce wind-blown spores that can infect apple and crabapple trees.

That is a great video on juniper rusts. Thank you!
Thank you
Very helpful. Thank you.
How intricate nature is. Thanks for the video and explanation
Thanks you for sharing your knowledge my friend it’s really amazing, unbelievable.
Haha lol had me rolling
Thanks you! This explains alot. We plan on removing the Juniper - which as been a problem for awhile. In the meantime, our ornamental pear tree pears is covered in the orange spores. Can we treat this or does the tree have to come down?
How do you eat Cedar apples
Great, I planted apple trees and my neighbors on both sides of me have a cedar tree. I’m seeing yellow spots all over all my leaves. Now what?
Go to your local garden center and tell them,they will direct you to the correct antifungal spray. Was just told all affected needs treatment every 2 weeks for a total of 3x, if left untreated it will kill the affected trees. The spores travel in the air. My juniper trees are infected (one in front yard and 8 in back) and we don't have apple trees near us. 😔 Going to be rather costly either way for us. To treat or cut down is my next decision.
I just planted apple trees a couple years back and wondered why the leaves got those spots. There are cedars everywhere. I will try spraying them
So big debate online.
Some people say removing the juniper/cedar trees will stop the cycle. Others have said that trees from "miles away" can still affect your apple trees.
QUESTION #1. Is removing the KNOWN juniper/cedars in my area going to help?
Some have said DO NOT spray rust with fungicide. Others have said it helps a great deal as long as you do it from when the trees start growing leaves in the spring.
QUESTION #2. Can fungicide help stop the process? Is there any you recommend?
I am looking for some help, I understand the cycle of the rust, and have removed the one apple tree that was here when we moved in.
Now our cedar trees are seriously covers with it and breaking branches, we need the cedars for a wind break and want to save them if possible.
Is there something other then copper spray that works cuz it doesn't. Please help 🙏
Sulfur spray.
