Interesting. Has anybody used Vegard in the field? Is it available?

RE: research paper biofungicide against poserdy mildew

The authors say that Vegard is a biofungicide developed by the Chinese that works almost exactly as well on powdery mildew as Benomyl but they don't say what it is or if it is available. I googled Vegard and there was nothing.

RE: research paper biofungicide against poserdy mildew

I didn't think anybody used Benomyl anymore. I am told that many years ago there was something in it that killed a lot of roses. The company never took responsibility. Anyway, I wish the researchers had tested Vegard against what people use now. I've never had powdery mildew so I don't know what they use now... but one needs to know what is available just in case.

Green Cure is an organic pesticide that works very well against PM, its active ingredient is potassium bicarbonate which is a food additive that has a GRAS designation. It is also labeled for black spot & some other problems but most rose people find that it only works well on PM.
