Where would I obtain the knot weed extract and what ratio should be used for concentrate and water? I'm finding it online, but mainly in powder form for human botanical medicine, is that the right stuff? All else I can find is in tincture form. Just to be sure I'm not misunderstanding your wording, this is for foliage spraying right?Something we did on our farm to try to prevent fungal pathogens like botrytis and powdery mildew was to apply an extract of Knot Weed concentrated watery extract once or twice during peak times for fungal activity.
Thanks for your time, I'm here in the pnw, and new pm remedies are nice to know.
