Milk spray works about 4 or 5 days, Green cure about 10 or 11 days listen lots of us get PM and we all know what will happen. You aren't linking us to any new cutting edge discoveries!!! Listen to the California boy here, I have PM on my roses out front.
Wish there was a cure for PM but once a plant is infected with it, it is kind of like herpies for the plant you can control it but not cure it. I am putting some through flower right now I know have PM, of course I skewered the environment to disfavor colonization so it doesn't occur in my op, but it pisses me off I made this Strawberry Cough strain I have with a male plant specifically and then I got it infected with PM. Anyone does find a new space age CURE please do post that right on up here.
