I've been having problems with PM so the other day I bought some Serenade. The company says this about it:
SERENADE Garden is made from a unique, patented strain (QST 713) of Bacillus subtilis. Bacillus subtilis strain QST 713 penetrates and destroys the disease pathogen, but does not harm beneficial insects or wildlife.
So I thought I would give it a try. The leaves on Pitbull were looking like this with PM.
This isn't the same leaf but it had PM all over it. I sprayed on the Serenade and now it looks like this.
It seems to wash off the PM and the leaf appears reasonably clean. I don't know now long it works but I sprayed my teenagers with it. Warning: this stuff stinks.
