Although mistaken about sulfur vs. sulfa, sulfur in both elemental and ionic form is strongly anti microbial. I use a good bit of sulfur on my plants for fungus control. In the soil, I don't imagine one would find large quantities of sulfur in these forms. So although sulfur is an anti-microbial in its own right, I've never shied from applying some elemental sulfur to my blueberries.

I haven't scorn enough for someone so stupid as to confuse *sulfur* with *sulfa*, a single chemical element with a specific class of compound. If I heard an organic farmer coming out with this nonsense, I'd be very leery of his or her so-called organic produce. -- Rodger Whitlock Victoria, British Columbia, Canada Maritime Zone 8, a cool Mediterranean climate on beautiful Vancouver Island _______________________________________________ pbs mailing list pbs@lists.ibiblio.org http://www.pacificbulbsociety.org/list.php
