Powdery Mildew

11 years ago

I weeded and trellised my parents old rose bed (the bushes are probably 50 years old if not more) of climbing cecile brunners last year. They've been doing pretty good this year, lots of new growth, but are being attacked by powdery mildew.

I'm using bayer 3 in 1 care. Should I just keep applying it every 7 days till it gets under control? It actually looks worse after the first treatment, at least to me, is that normal?

OH, not the 3 in 1! Get the Bayer Advanced Disease Control. It's specifically for fungal infection like PM. The 3 in 1 has insecticide and fertilizer in it too and you don't need to add those on a weekly basis.

The one I have has insecticide but no fertilizer. It's "disease, mite, and insect" or something like that.

I'll look for advanced disease control. Does it come ready to spray?
