Powdery Mildew and Eagle 20

Let me start by saying I have been growing for many years and this is the first time I have got PM. I tried to attack it early with organic solutions, but the problem persisted. I am an organic grower, and I oppose using toxic chemicals, but this was the last weapon in my arsenal besides cutting down the plants. I have spent too much time and money so that wasn't an option. The half life is 30 days, so it should be removed long before my outdoor plants finish. I will also be getting the buds tested at a facility to make sure all traces are removed. This year I changed some things up and my greenhouse exploded in growth, I think the extra plant mass is what increased the humidity and caused the PM. I have since defoliated and added more air circulation.

I applied the Eagle 20 2 weeks ago, with full safety equipment at 2ml a gallon. A lot of the PM is gone, which I removed myself, but I am still finding some spots here and there. Maybe a few leaves on some plants. I have looked all over the web and I can't figure out if the PM should disappear or if the eagle 20 just prevents the PM from expanding its reach to new growth. From the information I gathered, eagle 20 is systemic and people claimed it is the end all, so I am confused why I am still seeing some spots. If anyone has used this product before, can you please comment and share what happened after you sprayed it. Also worth noting that I sprayed in the day, all over the plant, and mixed it with well water. Not sure if hard water or sunlight could cancel the effects?

Again, I am aware of the potential dangers, I am an organic grower, so please don't preach to the choir with studies about how dangerous eagle 20 is. I am just looking for feedback. if the eagle 20 is not 100% effective, I am considering moving forward with a weekly spray of greencure to keep it at bay.

Thank you!

did you try neem oil ? and yes give them a hard wash with the hose and neem oil them and sun light will help .

Yes I tried neem oil first with SM90, it was effective but only temporarily, roughly a week.

Only way to completely remove it is with a surfer burner. I've read a lot of people swear by green cure if pm rears its ugly head. But it won't kill pm completely.

The shitty thing is now all your clones if you take any will not be infested with pm. It's just a guessing game when or if the pm will show on your next run.

No only way to kill powdery mildew 100% is eagle 20. That's it tho pm is systemic even if you don't see it it's there. I use eagle 20 but only on veg. It has a 30 day life cycle in the plants and I do 63 day flower so well out of the system by crop.

Bro.. that's what I'm saying.. I sprayed with eagle 20 two weeks ago and I still see some PM. Does the eagle 20 remove the PM, or just stop it from spreading? I was under the impression it was the "end all" as well so I'm not sure why I still see PM..

It kills it for 30 days if you didn't directly wash it off it'll normally die in a couple days/weeks. What was your dosage?

I heard that sulfur is another band aid solution and the only way to completely remove it is a systemic like eagle 20, but apparently that's not true either.

I applied at 1ml per gallon, then again a week later at 2ml a gallon. I hit every spot I could and I don't think I missed any, but these plants are huge so that can be difficult and if eagle 20 is a systemic it shouldn't matter..?

Ya that's a low dosage like the real low end. I know people who do 15-20 I personally use 5ml per gal with great results

Good to know

I saw people saying 5ml is on the high end, like the max. But since this isn't working I might give that a shot. I'm trying to make sure the problem is removed for good before flowering starts.

Ya man I mean honestly I know people who have done 45ml a gallon lol they never have anything but I also don't smoke their shit and tell them all the time they over doing shit lol

Lol bro that's crazy I can't believe they are giving that to people but thanks for the advice I'll definitely give them a spray with the 5ml dose

I mean they spray in veg and it's supposed to be in system for 30 days. Probably longer with such a high dose but then again maybe not. Higher dose doesn't increase the length of time it's supposed to work. Or atleast it shouldn't

Yea that's a good point man. That's the only reason I agreed to use it, because I am a strictly organic grower but when you are backed in a corner sometimes you have to bring out the big guns.

Agree I don't like it but if it stops pm and it's life cycle is only 30 days it only makes sense spray in veg only. I wish their was a better option

Green Cure works. Its natural,effective and can be used up to an hour before harvest according to the label (though I wouldn't recommend it). I used it in the second week of flower and the PM was gone the next day and never came back during flower. I did however use it at a full strength dose as the directions suggest. I would advise going 1/2 strength since it burned the tips of my leaves and turned the white hairs on my buds orange prematurely but they recovered quickly.

Used green cure once a week in a commercial setting. It washes it off thats it pm is systemic

Yea most people I have talked to have said green cure is a bandaid, but I have seen some people claim it worked for them. If PM is really systemic, green cure is not a "cure".

the label says 1-2tbsp per gallon, so did you use half a tbsp or a full? Also I don't mind if the pistils are burned a little, but did they still recover and end up producing nice buds? Thanks for the feedback.

It's burns em and I always did 1tbsp per gallon. Anything more seemed to burn too much. Might work for some people don't know how tho lol
