Bactericide / Fungicide

[kmccormic]

Hi Guys!

I've lots of experience with the practicals of chemical bug controls, but I've never worked with bactericides or fungicides other than a quick root dunk in Physan when trimming roots during repotting. It's winter with temperatures dropping and problems may come up no matter how careful I try to be about watering frequency. I'm trying to determine the best ways and strengths to use them. Are they media drenches only, usually? Do you spray the foliage with them (and if there's a difference in usage, how could you tell?) If plants are mounted, can you dip the entire plant in them and leave for 10 minutes or so?

I've read some online, and trying to determine the indications of fungal or bacterial problems is intimidating to me. Learning experiences! Most of the online references state "apply a bactericide" without listing specific brands.

Is Physan20 really a bactericide and a fungicide? I'd read somewhere that it really isn't both, despite the bottle labels.

I have Physan20 and just added Thiomyl and Phyton 27, and I've never used them before. Are there any other products you might recommend adding to my product index? And recommendations about using the ones I've listed? Or other advice in general?

Thanks for your patience and help with these questions!

Regards,
Kara
