This is a chineese noodle bean, and it is not happy. I have a row of Blue
Lake pole beans 2 feet away that are growing fine. All of the noodle beans
look like this. I don't believe it's insect damage. The weather has been in
upper 70s, lower 80s. Water is about an inch a week. Soil is well drained,
moderately rich loam. Growth is slow, and leavs are discolored and tend to
curl at the edges. All of them seem to do it. Once the get past a certain
size, the plants grow well, it only seems to happen when they are young.
Does anyone recognize this, or have any suggestions?
I have on plant that is developing discolored curling leaves:
The closest match is Alternaria Canker. It doesn't really tell you much
about it. I looked around for more information, but most web sites seem to
just copy each other. I gotta wonder how this one plant got it? It's in the
middle of the row, and everyone else around it is happy. I think I'll remove
the plant, and treat it's neighbors with a fungicide, as that seems to be
all I can do at this time. Several documents call for an application of
Not sure. I think a copper spray, which can also control this, might be a
better choice. Chlorothalonil is a very common fungicide, used commercially
on potatoes and tomatoes, but it breaks down to toxic compounds, and is
slightly carcinogenic. No one really knows what the long term effects are as
the symptoms observed in the lab haven't been observed in nature. It's been
used since the 1960s, IIRC. There are certainly worse things I can use, but
I still prefer something a little safer, hence my preference for copper.
Anyone recognize the bean symptom? It almost looks like a disease except the
plants usually outgrow it. My first guess would be that they just don't like
the climate/soil. The seeds come from China, and I have no idea what kind of
environment they are raised in.
I've found that often what we observe of disease or problems is taken
care of by the plant itself or actually causes little problem, other
than cosmetic. I had bean beetles show up and became concerned, but
they did littel damge and disappeared. Same for flea beetles on the
eggplant, which years a decimated my crop. Found three hornworms so
far is all, despite an abundance of adult sphinx working the flowers.
Maybe the cardinals are doing their job. I pay the effers enough in
Not always the case, of course.
Often time is the best cure. And of course healthy soil. Each year
that passes without my using any chemicals on my plants or soil and
continuing to build with organic matter, compost, etc, and never
tilling, I am finding fewer and fewer pests and problems.
Except for the damned cabbage looper things that love anything brassica
and wear me out handpicking catters and piss me off to no end. I've
likely done more damage by flailing away at the flying forms and
breaking plants than the worms destroy. ;-) This year I am planting
those things soon and try for a fall crop.
I raised chinese noodle beans last year, and seem to remember some
funky stuff early in their development. While interesting and a
curiosity, I couldn't get anyone here to be excited about them, other
than me. I did rather like them stirfried. I also enjoy carp, so I
guess I'll eat anything. We won't go into the culinary insect
experiments that are ongoing. ;-0

Um, yeah...my son is very much into culinary insect experiments ....
When do you plant cabbages and stuff for a fall crop? Do you direct seed
them, or start in pots/planters?
I grew the chinese noodle bean last year, but they did not do very well.
They did outgrow the deformed leaf stage when younger, but were never very
vigorous, nor did they produce much. I'm guessing they just don't like my
garden, but I'm not sure what they do like.
I have flea beetles and cucumber beetles, spotted and striped, so many that
they decimated my beans and melons, and darn near destroyed my eggplants. I
tried a few different things, but finally settled on neem oil applied every
4 days or so. They don't seem to like it, and the plants are just about big
enough that the beetle damage will no longer bother them.
