Mark, having just obtained the electronic version of Plums of North
America, I searched its cultivar database for brown rot resistance and
found the following info. In addition there was info on many cultivars
that are very susceptible to brown rot, but I have not included it here.
Unusually free of brown rot:
Very good resistance:
Comparatively free of brown rot:
Little or no brown rot:
Few problems with brown rot:
Burbank Stoneless Plum
Brown rot has not been a problem:
Moderately susceptible to brown rot:
Golden Drop (Coe's Golden Drop): not as susceptible to brown rot as
Kaga: not as much problem with brown rot as Tonka
Morris: more resistant to brown rot than Methley
Pottawattamie: escapes brown rot more than most of its kind
French Petite: no info
Stanley: very susceptible to brown rot; must be sprayed in humid areas
Also, peaches least susceptible to brown rot (from research at
Kearneyville, West Virginia):
Babygold No. 5

Subject: [NAFEX] Plum thoughts please
One of my in-laws wants to plant some plums and needs some advice. The
situation is that the plums will be low-spray, or possibly no spray at
all. I've seen the site and believe the disease pressure will be very
low. It is in the downtown of a city of 30,000. Lots of concrete, and,
as as far as I could tell, very few fruit trees around. So I'm hopeful
he can raise some plums without too much trouble from insects. Without
looking it up, I
believe the area only gets 30-35 inches of rain per year. Zone 6.
I want to recommend some high quality cultivars, but they need to have
some resistance to disease, specifically brown rot. I know about the AU
series of plums, and have some myself (that haven't fruited yet) but
I've heard too many negative comments about quality to recommend them.
Plus I don't think he needs something immune to brown rot, just
something not hyper sensitive to it.
French Petite- I've heard Ed, Lon, and others sing praises for this
plum, does anyone raise this plum without spray?
Superior- I have this plum ordered for next spring and have it
recommended by S. Smith and Ossi. Can either of you guys comment on its
susceptiblity to brown rot?
Any other suggestions? We can go with Europeans or Jap/Amer hybrids.
He has room for about four trees.
Thanks in advance,
