Anyone use Garden Safe Fungicide 3 for BS?
My husband has been spraying our 75 roses with chemical sprays like BannerMax and mancozeb for blackspot for years. I have a bottle of Garden Safe Fungicide 3 concentrate that I bought mainly to help with aphids...
It supposedly is a fungicide/insecticide and miticide.
Its ingredients are:
70% clarified hydrophobic extract of Neem oil
30% inert ingredients
Does anyone here use this product? Does it prevent blackspot, and how well? I doubt it could KILL blackspot spores already existing on the plant or in the soil, right?
Thanks for your help.
