i desperately would like to understand powdery mildew from a biodynamic perspective. all of the information on the internet seems geared at what fungicide to use, and differing opinions on how PM lives and works. of coarse all from a materialistic view.
i for the first time am dealing with PM on my indoor containers this winter. no, i never got around to applying BD508 before the problem, and using 508 now seems to do nothing as far as keeping the PM from spreading. so far i have only used fresh 508 as foliar spray, i have some fermenting now and should be ready (stinky) any day now to spray on soil. JPI told me that the fermented 508 should work as far as spread prevention but i am curious if it will totally eliminate further outbreaks. i have tried other natural remedy's but nothing seems to touch it. it is amazing how hard it is to get rid of.
i am wondering if it is possible to totally eliminate the PM from an infected plant. i guess i should have said that i am growing annuals not perennials?
if anyone reading this has some good info on PM PLEASE feel free to contribute.
