Has anyone here defeated powdery mildew?

@Jetdro, it sure seems systemic but every academic/scientific source I’ve ever seen says it’s ‘opportunist’ meaning the spores are everywhere (which they are) and just grow when they find the right conditions. The one guy had even studied the DNA of it and said he found nothing to make him believe it’s systemic…who knows lol

Also like I said I’m just certain if I kill everything and start again I’ll just end up in this same place a few months down the road. If I’m gonna be screwed anyways I’d rather just know now! I’ll check out that spray I haven’t come across that one before, thanks

@Buzzer777 that’s another product i haven’t seen before. I’ll look into that as well. The problem is alot of this stuff often isn’t available in Canada or is like 10x the price here. It’s nice of them to list the ingredients so I can try to copy it lol

@Foreigner yes this potassium bicarbonate is essentially baking soda and seems to work the best so far but still sucks lol… I’m using it with vegetable oil and dish soap as wetting agents

I did try milk once it came back fast and I wasn’t too keen on using something that can potentially rot like that in my garden anyways

Thanks all, some great info here! Hopefully this thread can help others going forward as well :+1:
