I followed Howard Sterns advice...kill it with heat.....had rooms at 108 for a couple hrs. Still see under scope...how to tell if it's dead? MY HUMIDITY/TEMP are perfect....air movement etc. Seems to be predominantly one plant...all chocolope .By the way, plants...no signs of stress. I guess if it spreads,duh, its living....l`'ll keep checking.

There are several threads here talking about PM and treatments....One of the best products I found, l IMO, and all certified organic is Regalia CG.

I've heard of that stuff from Annie, sounds great. I just looked it up on Amazon, and it seems hella pricey. I use Immunox by Spectracide, best stuff I've tried. My moms are in a tiny DYI tent, and they are jammed in there pretty tight. Before this product, they were constantly getting a variety of fungal infections (black spot, rust, pm, etc.) Now I just spray them every two weeks (just after taking clones) before I put them back in the tent. No infections at all anymore (it is systemic). It is super concentrated, one $15 bottle lasts me over 3 years. Just a cheaper alternative.

That stuff works (same stuff that's in Eagle20), but it's a nasty systemic pesticide, which stays in your plants for a long time, as it has a half-life of 64 days. I wouldn't use it on consumable crops.

I didn't know it was a pesticide, I just use it to prevent fungus. It states that it is safe for consumables, it lists fruits and nuts at the top of the packaging, and fruits on the picture. Most reviewers use it on grapes and tomatoes. In any case, I only use it on the moms, so the plants are harvested about 90 days after the application. I feel that it is fine, unless there are credible studies that show that it is not. Only about half of my customers die, but I can't be sure those deaths are linked to this product.

Yikes, that doesn't sound good. Thanks for the info. Luckily, we have a resident professional chemist in our midst. @cannabineer , what do you think? Should I stop using the Immunox the way I do?
I would. Consumption is not the same as combustion, and combustion assures you’ll get fragments of myclobutanil in the smoke, and I’m betting against their safety. Regalia is pricy, but it makes for weed that is safe to smoke.

The problem is many "organic" sprays do not reveal total composition....can only speculate on volatiles if combusted.......We breathe these spores constantly.....I rather smoke herb with a little PM than risk combustion of foilar spray residue. A group in Cali., AIRC is deep into these matters.

It's safe for consumables but not really safe for combustion in my estimation. I'm sure the tobacco lobby differs. Cannabineer can talk more knowledgeably than I about its combustion profile but Hydrogen Cyanide is one of them and I'd rather not smoke that.

I also believe Myclobutanil is a known reproductive inhibitor as well, and causes birth defects in rodents when they are exposed to it.

I sprayed Eagle 20 one time, then, 2 hours later, trashed the entire room, tore all the plastic sheeting off the walls, and trashed everything. Sprayed bleach water through my inline fans and everything. I had a little freak out to say the least.

I would not do that. Combustion doesn't necessarily kill the spores and they will reside in your lungs for years. If you are against Regalia I would strongly suggest killing anything with PM.

Here's a cheaper place to buy Regalia CG, $59 a quart no tax, free ship in USA. My favorite grow store. A quart will last you a year+


Then, IMO, you should also add their product for bugs, also certified organic, Venerate. Same price but I just got a quart last week on sale there for $40


Between the 2 you have a mighty good, all organic IPM, for less than a few dollars a week.

Check out their "Dank Deals"....Some great deals on all kinds of stuff we need at great prices, often with free shipping. I have gotten some incredible deals the past month.

You can even see on the bottle of fungicide above....myclobutanil ........this chemical upon combustion produces toxins....no good dude.
