Subdue maxx (fungicide)

[orchidsamore]

Banrot is a wettable powder and unless you have commercial sprayers with internal mixing the results can be poor. Wettable powders are not recommended for hand sprayers.

Thiophanate methyl has been recommended for so long to treat Thai Crud that almost all the variates that come in now are immune to it. I find the Vanda just outgrow the disease if given good air circulation and removal of the worst leaves. All the new growth is clean for me.

I also found Subdue is only minimally effective as a cure for Pythium. It is mostly used as a means to control spread of the disease. A pair of scissors cutting the bad leaf is still the best cure. You can usually find the generic in farm supply stores for under $100 a quart, but keep in mind it is not recommended for home use and actually illegal for the dealer to sell it to you.

Subdue does not work on Thai Crud.
