I like the concept, but I can not find any substantiating data. I think the only way to find out, is to find folks that have had a seed borne disease, did not use all their seeds, do a seed treatment with it and regrow some. It may not be conclusive data, but at least a step in that direction. It may help with only a few diseases but not all. TSP seed treatment, does anyone know if that was published before TSP became phosphate free ? Byron
