[nafex] My poor young quince--more options

I have seen rust on Chaenomeles - but not here at the house.
Saw a particularly ugly infestation on a single pear tree, years ago when I
was visiting the old Dr. Alexander Nunn orchard at Lochapoka AL... needless
to say, I didn't bring any budwood from that one...
I'm not certain which strains of the rust fungus I have here.  Certainly
cedar-apple, as I see the lesions on some apples (Gold Rush) and native
crabs.   Last couple of years, I've lost virtually my entire mayhaw crop to
rust infestation - mostly just hits the developing fruits, but I do have
one grafted selection (I've lost the IDs) that develops some ugly stem
lesions that necessitate pruning out.   Have not experienced rust on the
serviceberries here, but some we planted at the elementary school my kids
attended, about 2 miles away, get hit pretty hard most years.

Plenty of J.virginiana around.  Barring some blight that selectively took
them out, cedar-something rust is always going to be a factor.
