treating pm is one animal, preventing it another

plant health is key to prevention

I actually know of some old school legends on here that use it, I think most would agree, that they are worth their salt. Thats why I went ahead and ordered it. Knowing that spores are in the millions in my house, I know that I can't remove every single one. I did try on the last run to use other methods - reducing lights off humidity,extreme defoliatiion and lollipopping , got 2 wall mount hurricane fans to move air, milk spray, hydrogen peroxide spray, every 7 days, high intensity light per plant. I kept it at bay but all those treatments really turned my plants to shit and stressed them out. Ive never taken in clones or cuttings, everything is from seed. I got PM this winter, while it is -30C deep freeze outside. So its not something that was carried in recently. I think it was the high humidity in my home during the night. I recirculate my exhaust air through my home, I have no way to cut holes into the walls and roof to exhaust outside. Altough I think the solution is for me to vent into the bathroom and use the bathroom exhaust to vent that outside.

All of this was very taxing on me as I have a disability, and its hard for me to walk for more than a couple hours. All of my hard work was turning to dust in front of my eyes. Thats why I decided after seeing some members on here use it, to use it responsibly with 9 Weeks time between application and harvest.

Whether or not eagle20 is the correct treatment practice, I wanted to have a conversation at this time with other users and sharing our experiences. This can only help to determine if another path will be chosen in the future.




Good to know that you used 7.5 ml per gallon and it came back still.
I find that it usually shows up in bloom around week 3/4. I will add that it is not full blown pm, and not as bad as previous, so maybe the eagle20 if not 100% removing it, is minimizing it.I did spot it on a few small leaves only. This could also just be that the humidity isn't as high during lights of as in the past. I think that is the common theme for me so far. I have now dunked all 16 Scotts OG plants in greencure to help bring them to harvest. at 1 TBSP / per gallon, it did brown my pistils unfortunately.



Yeah I did use peroxide and baking soda last run, then got greencure for the end of the run, it seemed to work a lot better than baking soda. The thing with all of these dunks and sprays is these 4 Foot dangly OGs are hard to turn upside down and dunk or carry into the bath tub and spray, I have many branches snap and bend and colas break off during the process and it does make the buds not nice looking or smelling. and with 16 per light X 3 lights thats 48 plants to dunk every week. Its a lot of lot of work. I liked the idea of dunking once when plants are smaller before bloom and then youre good.

There are different strains of pm, and I think mine just rears its head when humididy goes up during lights off, so I think that is my solution to work on.



I was deciding between sulfur and eagle20 before I went this route. Reason is I have perpetual grow cycle, so every week new plants go into room. and the veg room has 10 cycles in various stages vegging (with Pm spores abound - not blooming but I know its on them).

so sulfur burning would not be effective I think.

Not legends if their recommendations are eagle20

Get the hint that members are trying to steer you away from it cause they know how bad it is an can’t in good conscience recommend using it at any rate. Hope you find a safer route

Good advise on above quote!

Myclobutanil

Myclobutanil is an active ingredient in the Eagle 20 pesticide brand, which prevents brown patch and dollar spot in established turf, ornamental plants, and certain fruits. This fungicide is considered “slightly hazardous” by the World Health Organization, due to its potential for nervous system problems and toxic fumes.

Exposure to Myclobutanil can result in symptoms like allergic dermatitis, vomiting, itchiness, nausea, headache, skin rash, nosebleed, and eye irritation. A two-generation study on rats found that Myclobutanil decreased pup weight gain, and increased incidence of stillborn.

How to Make Solutions Out Potassium Bicarbonate for Powdery Mildew

Are you wondering on how you can organically get rid of powdery mildew? Have you heard about using potassium bicarbonate for powdery mildew?

i find it takes 2-3 applications to work 100%

This is exactly why I don't smoke others cannabis unless I KNOW, KNOW, KNOW them.

Hacks out there spraying crap down with ornamental poisons. Collectively, science has very little understanding of how even safe levels of "non-toxic" "organic approved" pesticides react when burned and turned to vapor and enter the tissues in the lungs...

Spraying a cannabis plant with anything at ALL is a huge risk!!!

Every issue can be prevented through environmental controls and layering your defenses against contamination by following pharmaceutical clean room standards outlined in the code of federal regulations.

I am amazed that 10 years later and many threads later where we are and the best part is the conversations where shallow compared to the scope of effects

what other microbiology that helps the plant prevent PM is destroyed by eagle20?

use of these fungicides can force production of fungicide resistant molds and mildews where in there are methods for which there is no adaptation so use only makes the problem in a long term scenario worse

Run a perpetual to supply myself. I found it on my plants a few years ago. Scrubbed and cleaned the grow area and installed hepa grade filtration. Used alternating sprays of potassium bicarbonate and apple cider vinegar and that seemed to have worked for me.
Should I see it come back, I will try the milk.
