One of my figs has a pretty good case of rust going. If I don’t do something I may end up losing it. So… while out looking for something as minimally toxic as possible I ran across Serenade. It’s active ingredient is Bacillus subtilis, a soil critter related to the critter responsible for the Bt insecticide. According to the label it is effective on ornamentals as well as fruits and veggies against all manner of nasties including rust and powdery mildew. I did a minimal amount of research just now and it may or may not be as affective against powdery mildew as it states according to several researchers out there. I may have a chance to try it out as one of my lilacs usually gets it pretty bad. One Arizona study had good results using it against a disease in lettuce that I can’t seem to remember right at the moment. I’ll give it a shot and report back. Anybody else ever use this one? Opinions?
