Chemistry 101

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.

Here, I'll do it. 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.
