Stirring shit? Bro.. I suggested a poly cover to protect the plants from the 60+ days of rain they got, and you come back with some asinine comment about humidity, which is what got this off the rails. Yeah, lets just avoid the fact that they got rained on for two months, which is totally preventable, and focus on humidity. Great call there buddy! With all the experience you say you have with greenhouses I'm surprised that you think humidity is uncontrollable.
Placing a 6x6 sheet of poly above a single plant to protect it from rain is unreasonable? Not in my mind. Sure he might get rot anyway due to the high humidity, as you are insinuating, however it will at least give him a fighting chance. Forget the greenhouse debate, it will clearly go nowhere, and as you implied is irrelevant to the OP's situation.
It's not unreasonable. But the rh in the 90% and higher most of the year in some places will still get you.
Yes, fighting botrytis in humid conditions is often a losing battle. In my mind it needs to be hit from multiple angles. Of course controlling the environment (if possible) is always the first step to any IPM strategy. Perhaps in addition to the Regalia, the use of Southern Ag GFF, and silicates might provide additional protection against molds and fungus.
Agreed, but the step before all of that is strain selection. I learned the hard way this year.
