What's going on with my Dens?

This "ring" showed up again on one of the new growths on my den. microchip.
I cut off that leaf. don't want to see it again!!!!

Try spraying the plant with alcohol. I still have not seen a reoccurrence of this problem since I sprayed my plants with alcohol. I bunched some plastic wrap over the roots to protect them and sprayed down the leaves and canes for a few days and the disease has not progressed since then.

That is not an option because the plant is loaded with flowers. Alcohol will kill off the bloom.

There was a few months break between last break out and this one. so I thought it was gone, but it is back!

I have wiped plants down with alcohol on a tissue and it did not affect the blooms.

Agree, wiping should work. I have stopped spraying because my microchip is in spike. I just wipe the leaves in the mornings.
