Faced the prospect of adding commercial fungicides to 36 raised beds here at my research medicinal plant garden (as well as adding it to all the potting soil needed for over 300 pots for transplants and all the germination flats), I am appealing to y'all for help:
 
We are infected with Sclerotium rolfsii.
Is there any less toxic, and/or more biological fungicide that works as a preventative soil amendment (as opposed to using once plants are attacked)
 
Last summer, we tried beneficial nemotodes in all the beds where we were already noting plant death due to Sclerotium rolfsii. For whatever reasons, with repeated checkings through the summer, we could find NO evidence of any colonization of these nemotodes, so the botanist in charge is reluctant to go that route again.
 
There may be other non-beneficial fungi present, but this is the only one we have positively identified. It has been a problem on and off in the garden for years.
 
Though we buy new potting soil each year, the botanist also figures that it will become contaminated just from air borne spores, etc. so wants to treat that as well as all the outdoor garden beds. 
 
ANYTHING less toxic, even if still "chemical" is welcome, as we are not certified organic and do not go by OMRI standards, but nevertheless wish to lend as little support to Monsanto and its ilk as possible!!!  
 
thanks, nan in north mississippi
