Hydrogen peroxide and cinnamon are good remedies for leaf problems like bacterial rot or crown rot. Hydrogen peroxide can be poured directly into the crown of infected plants or it can also be dabbed onto leaves (that have an obvious wet spot) with a disposable cotton swab. And cinnamon can be dusted onto wet bacterial rot on leaves or into the crown.

Using Peroxide:
So, if you're suspecting crown rot, one way to prevent it is to pour about a teaspoon full of Hydrogen peroxide on the crown of the plant once per week. Peroxide works very well because it is such a good oxidizer. Being a good oxidizer allows the rupturing of cells of both bacteria and fungi which in turn, kill the organisms. I suggest only using the 1 teaspoon per week. Using more, especially if you think a plant is really bad and probably needs more, will do more harm than good. Completely washing/flushing your orchid with it will harm the chlorophyll molecules in your plant. These molecules are necessary for your plantshealth and survival.

Or if you wanted to try something else, some people buy Kocide 101 and make a paste with it, then they use a q-tip and paint the inside of the crown with the paste. Some swear by this and say that they never got crown rot after using it. (the only downside is that I read it was like $54 for just an 8 oz bottle)

Physan 20 is something else that can be used, but it would probably only be helpful mainly as a preventative of crown rot and less as an overall treatment and it is only a fungicide, not a bacteriocide.

Phyton 27, is a preventative also, and unlike physan 20, it not only helps treat bacterial infections but also fungus.


***if you want my opinion, i think trying the peroxide is your best bet. It is accessable at pratically any store, it is cheap, and has been known to really help and be successful at it.

Hope this helps some.
