Fungus or Pest Residue?

Post by bayarea41 »

I have inspected multiple days and unable to find any tiny insects hiding under/inside anywhere. I'm not convinced it's Mealy Bugs, but could be.
Its not cob-web like. More like dry paint, flakes off.

Perhaps sooty mold (I read it can be white also).

I have Safer Brand 3-in-1 Spray (Insecticide, Miticide And Fungicide), but did not want to saturate the bamboo with it unnecessarily yet.
It appears to still be growing branches and leaves just fine.

I've got a heavy dose of it here and I think it is mealy bug. Pull off a culm leaf or leaf sheath and it is lousy under them.

Okay, thanks. Went ahead and sprayed it.

Pulled back a few sheath's but did not see anything. They must be really hidden.

I am living with a big crop of bamboo mites out here, I've not even tried to fight them but this looks like white paint ran down the emerging culms on many species and the closer I get to the sheathes I start to see substance and then cotton, under the sheathes it gets ugly.
