Physan is a particularly effective disinfectant, but it is topical only and will not help control systemic diseases.Thanks! I think I might actually have some Daconil sitting around somewhere. I've been using Physan religiously, but it doesn't seem to address some pathogens. I'll give the Daconil a shot this week and see what happens. At recommended dosage, of course
Good info. I have been using Physan religiously to avoid bacterial issues, but I'll try discontinuing it for a while and using Daconil periodically instead. Thanks!The "whiting out"spots on your leaves looks somewhat similar to a situation I encountered with my Paphs a few years back. To prevent the chance of bacterial infections during the dark, winter days of November and December here in northern Minnesota, I tried adding a small amount of Physan 20 to my regular waterings. A month or so into this regimen, I noticed white spots occuring. I discontinued the Physan 20 and the leaves were greening up by March. This may not be your problem, but it is something to consider.
