Preventing grey mold on cucumbers in greenhouse?
Cucumber None Given
I own a small greenhouse that lets me get a head start on some of my vegetables. Last year my cucumbers were afflicted by what I believe was grey mold. Once it hit, it spread quickly and I was at a loss what to do. Can anybody provide me with some advice on what to do this year to prevent it? I try to avoid chemicals but if that is the only solution then what should I use?

In the Pacific Northwest botrytis (grey mold) can be a real problem.Avoid overhead watering to keep the foliage dry, remove and destroy any infected leaves. I've had good results with Actinovate as a preventative measure.It also works on black spot and root rots too. You can use it as a soil drench or foliar spray, the soil drench colonizes the the roots. I don"t know how it affects the mychorrhizal activity, maybe someone else does.Its made by Natural Industries and many organic gardening suppliers carry it. Hope this helps. K.

From the Actinovate product sheet: "The active ingredient in Actinovate AG colonizes the root system and protects it from harmful fungi. When used as a spray, Actinovate AG effectively suppresses foliar diseases such as Powdery and Downy Mildew, Botrytis, Monilinia, Anthracnose, Greasy Spot, Sclerotinia, Alternaria, Erwinia and others."

Heard about using milk sprays to prevent and treat powdery mildew while starting grape cuttings and found many articles. This may be right up your alley to help clear up your mold.
