Spots on culms
Anyone care to venture what this is? It's becoming quite prevalent on the older culms of my B. Dissemulator
Someday maybe I'll find a bamboo my wife likes...in the meantime I'll keep planting more!

Re: Spots on culms
It might be some sort of fungus judging from the trace of white inside what appears to be a burn spot. Very weird looking.

The legal issues that will arise when the undead walk the earth are legion, and addressing them all is well beyond what could reasonably be accomplished in this brief Essay. Indeed, a complete treatment of the tax issues alone would require several volumes.

Could be sunburn. I haven't had it happen, but I have received plants that the culms were black.

Re: Spots on culms
I've got lots of that on many different plants. The ones with the spots are in full sun. I agree w/ mantis, it's sunburn.

Re: Spots on culms
I'm going with insect borne virus. The insect carries the virus nibbles on the culm, and bingo infected. It appears that all of the lesions have a central point and an outward spread. Whatever it is starts in the middle, and then spreads equally toward the borders.

Re: Spots on culms
I have to disagree about the sunburn. These are all on the older culms on the inside of the clump, that majority of which does not get much sun at all. It's at various parts of the culms, even in locations that face the fence and I know for fact this part gets no direct sunlight. This same spotting is on some of the branching as well. Here's a wide angle pic showing the location of the bamboo with the problems....
Clump 1
Clump 2
I circled some of the spots facing the camera in the second pic, but again, these spots are in spots that get very little direct sunlight.

Re: Spots on culms
Can you examine the spots under a microscope?

Re: Spots on culms
Thanks Tony, but I think this might be a little different than black spot fungus found on the leafs of plants. I was hoping that maybe someone else here on the forum has seen this on their bamboo and would know exactly what it is. Certainly I am not the first one to come across this.bambootony wrote:Hello webgator,

Re: Spots on culms
I vote mold, take a cutting to your local university biology department. Perhaps they will look at with tools and knowledge we don't have available.

Re: Spots on culms
If it ever stops raining I'll try some fungicide. At the extreme I might thin out all the older, smaller culms and dispose of them before any treatment.
My wonderment though is out of the 15 bamboos in my yard, this bamboo is the only with these spots.
