[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

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!).

See Dr. Nina, I *have* been listening to you!

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.
My juniper survived. but I had to get rid of the Haw thorns they were reeking havoc on my juniper

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.
