It's like Perranah by AN and that stuff can really hepl if you have mold or fungus, I had some blueberry clones mailed to me that had "some type" of fungus.. damping off... and that stuff brought them back from the brink...
Outdoor growers are using it on there buds to prvent mold... it uses up the food source (takes the place say the dreaded gray mold) good stuff for emergancys!!
