RE: Baking Soda/Powdery Mildew
Thanks Carlos,
I already bought this product at the end of the last season but I didn't use it so far. I'm looking forward to use it this year and to see how it works. Here in Germany it is sold under the name of "Ortiva" from Syngenta. And the best thing is that we do not need any licence here in Germany in order to buy and use it.
Does anyone know the active sustance of "Nova"?
Best wishes,
Martin
