Tis the season to see Fungi, fa la la la la....

I enjoy your threads David, very educational and well documented.

 

Has anyone ever tried mitigating fungal growth/reproduction above ground using artificial UV lighting during the night time hours?

 

May seem like a dumb question, but I'm thinking of trying it on Phoenix canariensis date palms infected with fusarium wilt in their heads by placing the UV lights in close proximity to the infected areas. About six feet, and only giving the tree a few hours of true darkness.

 

Your opinion on this dumb idea would be appreciated.

Found this today any ideas,The trees owner is worried as its on a main road over a bus stop used by loads of school kids.its about 6m up the stem.

Looks like Ganoderma australe from where I'm sitting. Bit of a concern up near crown break and with what looks like a recent and sizable branch failure.

I'm not familiar with that type of application jomoco, haven't read anything about it.

 

 

But I think uv has been used against the spore of mold in buildings etc.....

Thanks Sloth the branch failure happened in high winds its about 14 inches across,the rot is soft and pulpy.Its in conservation area so we will get the county arborist to have a look but my gut feeling is "chainsaws at dawn" cheers

I am curious to know what this is. The smell of almonds is bezaldehyde. I think many fungi (and plants, notably Prunus) produce it as an insecticide. But both benzaldehyde and hydrogen cyanide are bi-products of the fermentation or breakdown of phenylalanine, a common plant and fungus protein. The smell could be from concentrations of these in the fungus but with the original source being the tree.

 

I could be talking mince, though. I would have been tempted to take the bracket in context to be Perenniporia fraxinea.

 

good shout that, Perenniporia I mean.

I think you might get some interesting results, there was a guy who did a talk at a BMSmeeting about three meetings (annual) ago who spoke of the effects of light and other stimuli effecting the growth and morphology of fungi.

 

I cant remember his name now but im sure a little research could dig him out:thumbup1:

Interesting hypothesis Jules

 

.

 

I knew I'd seen it somewhere!

 

Conversion of Phenylalanine to Benzaldehyde Initiated by an Aminotransferase in Lactobacillus plantarum

 

Concentration of benzaldehyde in the fungus seems to me more likely than production of it by the fungus.

Havent looked it up yet but at a guess

 

Oyster
