Silica/Silicate as a material to control diseases in greenhouse
crops can be found the ag journals. In Canada, I'm pretty sure it has become a regular greenhouse industry practice to use something like potassium silicate. It is good for pythium and mildews on crops like greenhouse cucumbers. Quarles, W. 1995. The truth about horsetails or natural

So far, I'm turning the cuttings, etc into compost, trying to phase out vermiculite for the (locally available) cinder, brewing compost tea, etc. I've heard, mostly through anecdotes and biodynamics texts, that silica is an effective remedy for mildew & fungus diseases. Currently, the nursery is using some sorta biocide spray for this (we're on the wet side of the island). When the ironwood discussion came up, Robyn posted a quick and simply ironwood tea recipe for fungal spray. This would be cool, cheap, local, etc but I need some sorta reference to back up these claims. Does anyone know of any studies, reports, books, etc to that effect? |
