[IBC] Crab apple root gall
I have come across Rust on my Hawthorns and Junipers sometime back.They
appear as galls. I had to keep my Hawthorns away from all my other trees to prevent it spreading. I eventually dumped all the Hawthorns. Rusr usually affects apples, but I was lucky ************************************************** ****************************** ++++Sponsored, in part, by Ken Rutledge++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

[IBC] Crab apple root gall
Hi Steve,
I have come across Rust on my Hawthorns and Junipers sometime back.They appear as galls. Yes, and soon they'll be getting nasty slimy orange spore masses. But, those are only on the upper parts of the tree, yes? The galls people were talking about were root and crown galls, I think. I had to keep my Hawthorns away from all my other trees to prevent it spreading. Generally good sense, but actually, the only trees you had to keep it away from were junipers. Even other haws wold have been fine - those rusts have "alternate hosts". That is, the spores from the form on haws only infects junipers, and vice versa. I eventually dumped all the Hawthorns. That's one real solution, alas :/ as long as your near neighbors don't have haws in their lawns. Rusr usually affects apples, but I was lucky Lucky? Well, so far! The cedar-apple rust is a different species from the cedar-hawthorn rust, I believe. Our own Nina Shishkoff authored an excellent short article on the rusts in the ABS's journal not long ago (would be worthwhile to have that on the Web somewhere!).

Thanks all, especially Nina. I now see that my earlier diagnosis was
incorrect, definitely not crown gall, more like an aphid infestation causing root galls. I am now wondering if there's any link between these and a type of woolly aphids that appear annually on the same apple trees. These orange brown aphids with white fluff emerge from bark swellings near twig tips. They appear to have overwintered beneath the bark. I usually deal with these once a year with a Q tip and meths but they usually return the following year. Reading up on aphids has opened my eyes. Some do live in colonies inside galls. Some in exceptionally large galls. Thankfully these don't occur on apple!

I think the Hawthorn and the Apple are of the same genus or family and were affected by the same Blight. The disease was traveling back and forth from the Juniper and the Haw-thorns.

I think the Hawthorn and the Apple are of the same genus or
family and were affected by the same Blight. The disease was traveling back and forth from the Juniper and the Haw-thorns. Haws, apples, pears, peaches, plums, and several gazillion other genera are all members of the Rose family. They all share several TYPES of diseases. I THINK it is unlikely that the haw and the apple had the exact same disease (unless it was fireblight), but they each get their own kind of rust and I think junipers are the alternate host for each. I've never seen a juniper killed by the rust -- tho they can look messy.
