What is this and how do i stop it?

I have lost many cherished plants to Erwinia through the years, despite using many different things to treat it. I can tell you that Phyton is an absolute game changer. The gold standard. I don’t spray it on flowers or on Dendrobiums, as it could harm them. I also do everything I can culture-wise to grow healthy and disease resistant plants. Do not fear Phyton. It works. Period.

100% isopropal alcohol between each cut!

100% isopropyl won’t kill orchid virus. But for bacteria/fungal probably ok, on same plant.

I’ll second that. Others swear by BanRot but I’ve never used it. I do have it, though.
