Not true. I have successfully eradicated pm not this late in flower but pretty late (around 34 days)
Green cure, 2 days later a mild solution of h202 sprayed just before lights on.
Get 100 percent coverage. Lots of air flow!!! get as many fans as you can in there. under and over the canopy.
Heres the problem, youll be spraying which is going to raise humidity. You need some way of ventilation or dehumidifier from here on out if you want any chance of saving them. If you can't figure that out, youll be wasting your time.
Not that anyone would want to, but jorge cervantes has a video on how to wash your pm buds in a h202 peroxide mix during harvest which he claims washes the pm away saving your buds.

Either way, spend the 10 bucks on green cure and some h202, pick up a few extra fans and do what you can with what you have.
a day or two after spraying green cure, spray the mild h202 solution with full coverage. Go ahead and spray your equipment, walls, potters and everything else. Then turn it into a hurricane in there with as many fans as you can.

The problem with this is, PM is in the plant, not just on the leaf surface which we see. Some fungi also release toxins and those cannot be washed off. When you find a moldy strawberry what do you do? Throw it out right?

I'd smoke it.
But it's marketability might be dented a little.

Read this discussion I had about using milk to treat PM on plants in flower (it is fairly short thread)--as well as other PM alternatives.

Baking soda and water. Two teaspoons baking soda to a gallon of water. Spray before lights off. Will kill the PM and stop the spread.
I have never done this at that stage of flower with cannabis. Vegetables get the spray all the time.
Worth a shot.

Oh yeah, I have used the milk routine before--and sprayed as late as a few days before harvest. I recall that particular batch (doubt I would never forget those days...lol) was sprayed every few days during the last 4-5 weeks in flower and definitely were not beauty contest winners. But I got across the finish line with a product that tested zero PM (that dispensary tested everything back in those days) and it smoked a few notches above mediocre. Seriously.

Similar situation. Grow rooms in a basement. It's damp and cold. Perpetual PM threat.
Spectracide immunox can be used to treat mothers in veg, to at least stop it there. It's active ingredient is myclobutanil, which is a systemic fungicide. This is the same active ingredient in the somewhat controversial Eagle 20. Myclobutanil is commonly used in commercial crops. I think the danger lies in combusting it (IE smoking something that has residual myclobutanil.) But, if you do spray it in Veg, hopefully you've got nothing but fan leaves - no developing buds. So nothing you're ultimately going to smoke should be present on the mother plants.
Anyways... That's what I do in the mother/veg room.
That stuff will keep PM away for a few weeks before it wears off. In flower, though, I kept getting it after week ~4.
Tried all the home remedies. Baking soda/greencure/etc, trying to use a spray to raise leaf pH. I've only got 4 trays, but still couldnt keep up with it.
Enter a sulfur burner. I now do a 2 hour burn every 3 weeks or so, and haven't had PM since. It will coat every surface in your room and affect surface pH. Wasn't ever able to be this diligent with a hand sprayer.
It'll stop PM. Bud rot/botrytis can still be an issue if you've got a high RH. Remedied that by cutting giant cola strains out of my rotation.
TLDR: consider a sulfur burner.

PM preventative/ treatment
PM preventative/ treatment
I run a dehumidifier every night. During the day the humidity is fine but at night with lights out- i need it. It has made it so I don't have to worry about it but I use a product as a preventative. Its great to prevent PM and pests. Its called Organic Cold Pressed Neem Oil Wash and its made by Potent Growth. Here's a pic and if you mix by the directions it comes out perfect and doesn't burn up the plants even when lights are on. I stop using it 3 weeks before harvest. Awesome product!
