chloroplast Posted June 3, 2009 Report Share Posted June 3, 2009 I have a Cephalotus suffering from a chronic powdery mildew infection that seems resistant to my fungicide of choice, tebuconazole. I have heard anecdotal reports on the efficacy and safety of baking soda spray for the prevention and/or eradication of powdery mildew on common houseplants, but I've never tried it on Cephalotus or other CPs. Does anyone have experience with this on CPs? I found a nice site that summarizes some studies on the subject: http://attra.ncat.org/attra-pub/bakingsoda.html Thanks, Ken PS: Other recommendations on safe/effective fungicides for powdery mildew on CPs would also be appreciated.

Alexis Posted June 3, 2009 Report Share Posted June 3, 2009 I wouldn't put anything highly alkaline anywhere near most CPs. Quote Link to comment Share on other sites More sharing options...
rsivertsen Posted June 4, 2009 Report Share Posted June 4, 2009 Sodium ions are harmful to most CPs, baking soda is sodium bicarbonate. You could just dry it out a little, as Cephalotus can handle a little drying. Maybe it's just too wet. - Rich Quote Link to comment Share on other sites More sharing options...
chloroplast Posted June 6, 2009 Author Report Share Posted June 6, 2009 Thanks for the replies. I agree with the both of you that sodium bicarbonate is probably not a good thing to spray on a CP. That's what my intuition suggested, but I posed the question anyway as my intuition isn't always correct! Quote Link to comment Share on other sites More sharing options...
