So it is that time of year where I live that this starts to become a problem.  Living close to a lake and hurricane season pushes warm air and fog into my area. Tomorrow I am back at pruning for better air flow etc ... and have some potassium bicarbonate on order. Any tips for fending off this garden killer?  My best options here are resistant genetics and air flow.  However I am testing different strains this season and some are more prone to this problem.

Apparently Milk is good for treating them...40% Milk to 60% water and spray weekly, also Neem oil helps keep it at bay...The spores are in the soil and bad weather sweeps them up onto the plants, can you protect the bottom of the plants in some way to avoid this ?

No experience of PM personally

I`ve used Neem oil in the past and it does work very well for pest control.  But from articles I`m reading now it might cause vomiting in people that are considered heavy smokers.   Quite a few of my fellow growers in the area are now experiencing PM this past week, so it is only a matter of time.

i got this as a sample for preventative and treatment of pm. It’s comparable to zero tolerance by Ed Rosenthal, essential oils for ingredients. I don’t have pm but I tried on my zucchini so I’ll know if it works in a few days.  I’ve heard nothing but great talk about zero tolerance so try that if u can find.
