What about the issue of resistance being caused by overuse and misuse of Eagle 20? Let's let go of the environmental issues outside of creating resistance for a minute, let's go ahead and let go (amazing concept considering this might also be considered a MMJ site, but hey, there it is) of the facts regarding environmental and other effects.

Eagle 20 is known to cause resistance in PM fungi. And you don't have to use Google, all you have to do is read the label on your bottle of Eagle 20.

So, considering how lax the vast majority of cannabis growers are about damn near everything, including reading labels, how soon do folks think we'll be experiencing what apple growers, for instance, are experiencing? Nothing like those Floramite-resistant mites, either, eh?

And can anyone elaborate on the Immunox that is available at Home Depot for like $15? If it has the same ingredient but is way cheaper then wouldn't it obviously be the better choice instead of Eagle-20??

How many ML per gallon are people using of the Immunox?

Executive summary, use 1tsp of Spectracide Immunox® Multi-Purpose Fungicide Spray Concentrate per 25 floz sprayer bottle, or 5tsp/gal, plus a drop or two of soap. Maximum 1 3/4 tsp per 25oz spray bottle or 9tsp(3tbsp)/gal(according to dow application rates). Complete coverage is important. Apply again in 10 - 14 days as required.

I have used this at 1 tsp per 25oz spray bottle and it rules.

As stated by someone earlier, Myclobutanil is Myclobutanil is Myclobutanil... so only dosage matters.

Pardon the insignificant figures and not doing a proper w/w conversion. Round as you like. My computer loves big numbers. I round at the end. This is close enough.

Eagle 20EW = Myclobutanil 19.7%

From Dow, "Apply to vigorously growing plants on a 10- to 14-day application schedule at a rate of 6.0 to 12.0 fluid ounces per 100 gallons (dilute spray)"

12 US fluid ounces = 354.882355 ml

354.882355 ml / 100 gallons = 3.54882355 ml per gallon

or 1.774411775(min) to 3.54882355(max) mL/gal (suggested 2mL/gal mix in this thread)

Spectracide Immunox Multi-Purpose Fungicide Spray Concentrate = Myclobutanil 1.55%

19.7 / 1.55 = 12.70967741935484

1.774411775mL(min) * 12.70967741935484 = 22.55220126935484mL/gal = 0.762580646 floz/gal = 4.57548387 tsp/gal = 1.52516129 tbsp/gal

2(recommended dose) * 12.70967741935484 = 25.41935483870968mL/gal = 0.859530642 floz/gal = 5.15718385 tsp/gal = 1.71906128 tbsp/gal

3.54882355(max) * 12.70967741935484 = 45.10440253870968mL/gal = 1.52516129 floz/gal = 9.15096775 tsp/gal = 3.05032258 tbsp/gal

25 US fluid ounces = 0.1953125 US gallons

5.15718385 tsp * 0.1953125 = 1.007262470703125 tsp = 1tsp per 25 floz sprayer

9.15096775 tsp * 0.1953125 = 1.787298388671875tsp = 1 3/4tsp max per 25 floz sprayer(maximum dose)

This is verified by being similar to the Spectracide Immunox application rates. Spectracide includes a nice bunch of instructions for many different crops but above is the 2mL/gal Eagle equivalent.

First post! w00t! w00t!

Hello all..I would like to thank Krunch and everyone who positivly contrubited to this tread savin my ASS..Those were not trichomes frostin up my gurls...$$$$ was at -0 so I used every trick in this thread while waitin to get Eagle 20..BTW I run Perpetual Hydro..

In this process I tried a product from organic labs makers of organiside(the fishy stuff)..At the time it was called Excell LG,now the name is 'Plant Doctor'...gets two thumbs up....does not kill PM per se...it triggers the plants natural defences.it it a phosphite (PO3) not a phosphate (PO4)...can be used in a rez and sprayed.. since it has 1.0% soluable silica one of the beneficial side effects are large buds with more trichs in less time.

I hav recieved a couple more products from these folks, Resin8,and Invigo8. My plan is to do a side by side with some GrindHouse Gurls and see if I can stack even more firei goodness in these babies...

Again Krunch and to many to name Thank You...I found this post a fuckin Life saver..never had PM before going all out....TY TY TY TY TY....pal

2 oz. per gallon from the label
I use it in veg 1-3 times and pm is gone until you bring in infected plants. I haven't had to use it in over a year. it won't burn they seem to like it. I dont go back in till its dry.
pm wont be an issue, this shit works!

Eagle 20 is known to cause resistance in PM fungi. And you don't have to use Google, all you have to do is read the label on your bottle of Eagle 20.

So, considering how lax the vast majority of cannabis growers are about damn near everything...

It is intelligent to use a variety of treatments for all things regardless of it a fungal infection or a garden pest. This should be common and standard practice and is a good point to make. However, this type of resistance is only going to occur in a situation in which the grower never actually gets his conditions in check and allows the root problem to remain. The purpose is to not prevent it time and time again, but to CURE it in the first place. Something can not become resistant if it is no longer in existence. If you treat the plants AND take the steps to bleach/peroxide every surface and then treat with a commercial mold/mildew preventative...you have INSURED nothing remains. The continued treatments while in vegetative growth, will only act as a permanent barrier that will prevent PM from ever even getting a foot hold in the garden again...

Keeping in mind, PM is a spore and can even be carried into the garden via your air conditioning or on your clothing. It is important that once you have a secure location, you treat the entire PROPERTY for all and any signed of PM. This could also mean removing certain kinds of plants that are known to encourage or harbor PM and other such fungal spores....

The point being, Eagle 20ew is an excellent tool in the battle against PM....MOSTLY, because it defeats the problem from a systemic approach, which is important in ways I only recently began to understand. I did all the above measures and never used Eagle 20ew, and PM kept coming back...even in the most UNFAVORABLE conditions. This was because the plants themselves had the fungi contained in their cells and was being passed from cut to cut to cut....cycle after cycle. If you do not defeat PM systemically, NOTHING you do will EVER rid you of it. You might be able to keep all VISIBLE signs at bay, but the scary part is it is STILL in the buds, still being consumed...unless you treat it systemically. EAGLE 20ew WORKS. Just use your brain when using it.

On a side note:

Your second comment, though, is what I find to be borderline offensive. I am not nor have I ever been "lax" in ANYTHING I do...I am a perfectionist if anything and DEMAND the very best of myself. Thus the reason I grow...because I DO DO IT better than "the next guy". I think that is a MUCH more accurate assumption of the growing population here at ICmag. We throw down the gauntlet every time and push each other to better and higher standards daily. This community is NOT one of stagnation and laziness. It is the pinnacle. I think such a character trait (lax) is more specific to an individual person, NOT the generic group you addressed.

If you feel this trait is fair to be broadcast upon ALL us cannabis growers and users, PERHAPS it would be wise for you to re-examine the type of people you have surrounding you in your life...

Just saying.

Although this is not my thread, I addressed this some 500 posts ago. Anyway, a good rule of thumb is to rotate your fungicides (active ingredients). We do as a rule in farming as table grapes are a crop prone to PM.

Also, if I were clean with no infection, I wouldn't spray any fungicide at all. I haven't used any on this crop for almost 2 years. but it's sitting on the shelf in case I ever see PM.

Is Spectracide Immunox Plus Insect & Disease Control multi-purpose concentrate just as effective?

It is only 0.78% of Myclobutanil, not 1.55% like the fungicide concentrate. Being half as concentrated, probably 2x would do it as far as the Myclobutanil dose is concerned. The problem is it also contains pesticide that you would be applying.

Reading the label shows you that the "plus" is recommended for ornamentals only. Myclobutanil and Permethrin are both used on food crops so they are probably just saving themselves the lawsuits.

You might want to research the application rate of Permethrin on food crops and report back.

Cats and fish are sensitive to Permethrin, FWIW. Don't want to go killing Mr. Cuddles taking out the PM.

That they can afford to keep up with labeling requirements?

You do know that this document is almost 20 years old don't you?

The product is still being sold. What does that tell you? Anything? Anyone?


Umm .. seems like it would mean that it's a safe product to use if they reviewed it and decided to license it stating that it had low risk and toxicity, and 20 years later no new information has caused that decision to be changed.

Where were you going with that?

Yeah, I read it and it seems like it is supporting our view that if used when needed and as recommended, it is safe. Those animal studies are on Dow's website.

A good part is the mention of exactly how non toxic the stuff is. The exposure rates are set with a 1000 times margin. Try taking 100 times too much the max recommended dose of "safe" aspirin or tylenol and see how well you are doing. You won't get to try 1000x.

The troubling part to me is that people are going to overuse this product as a preventative measure. If you are indoors and not experiencing problems, don't use it. If you are bringing in dirty whores from your local co-op, spray and isolate them, not your whole grow. Bug blast the sluts while you are at it.

Also notice the stability of this product. This shit never goes away. Please only use what you need. The earth has fungus that we need and this stuff kills everything.

As grapeman has said over and over, the smart farmer rotates products.

As many people here have said over and over, a smart farmer avoids lots of these problems by operating a clean and dialed in room.

I really hate PM and love chemicals, but the best fix is to not let it in and establish itself.

How about outdoor growers? How do we operate a clean and dialed in room?

SeaMaiden, yeah, that's a tough one. Probably the reason our rivers are toxic messes, our oceans have dead zones and pesticides are in polar ice.

There have been great advances in integrated pest management. ATTRA has lots of good free info.

Mother Earth News, too.

I have tripped out imagining our future farm's macro and micro herds vibrating together in a moving fractal quasicrystal proof of the innate goodness and ordered nature of things... knowing inside that if we stop forcing the game, we allow the cosmic machine to turn as it should... perfect being as the sparkplug between dimensions... realizing our potential in an explosion of consciousness...

Perhaps you can brake the code and help us all out?

Member of ATTRA, MEN is a start but they pick and choose what information they publish.

I simply rotate physical controls. I use stylet oil and OxiDate most often because they're easily available in large volumes. I used E20 once on some plants that had it vectored by root aphids and that was the one time that I could not get it under control. But when I read the label that stated it causes resistance I started looking into it more deeply, and decided it's just not the product for me.

Oh, and watch out for Brownian motion.

lol, ok. I wasn't sure if you were trying to lead in the other direction or what.

also, fwiw, my PM had an incredible resurgence. Really nasty. But I think my trouble may have something to do with a root aphid infestation I've recently discovered. I've dealt with them and am going back to clones only and re-treating with Eagle 20 one more time.
