That is not what Frits was getting at. He wants to induce resistance to
pathogenic strains of mildew by spraying with nonpathogenic strains. That
is a neat idea, maybe it can work. There are chemicals that induce systemic
resistance when sprayed on plants. This is a hot topic in the ag chemical
industry, and we are trying out an inducer to control rust and other
diseases in corn seed production. Jasmonate and salicylic acid are
inducers, and I have heard (but not tried) that aspirin does interesting
things on plants (including killing at sufficient dose).
