Oh my.. I have been trying to fight this same blight with lemongrass extract for the last two weeks. It hasn't worked. I have also noticed it on other plants.
Crazy to see so many affected by this. My Blueberry caught it one night after humid/stagnant air, then I noticed it on some ?Skunk Red Hair?, luckily this strain seems a LOT more resistant to it.
The blueberry seems a lot more susceptible but it has also had low pH problems, causing stress.
I am going to try Eagle 20 - but fungicides can be very toxic to humans, so I have to do some more research on the molecule and its effects before I go spraying it everywhere.

Looks alot the pics in the thread if they are outside i'd guess yes, couldn't hurt to treat them. Remove all infected material first

Eagle 20 is good stuff, works against Powdery Mildew, Botrytis (gray mold), and all sorts of other fungal diseases. It works with one application as a systemic fungicide that does not need reapplication constantly. That being said, it's truly safe for use in veg and not while flowering is occurring. Although if you still had 6 weeks to go, I wouldn't stress a light dose. Also, it's no joke. Wear gloves and cover every damn hole on your body while spraying it. Price wise, probably the best option all-around. One bottle purchased off Ebay for around $54 will last you until approximately two years after hell freezes over since you use so little per gallon or five.

So next year this would be the way to go. You have used it i was reading did it work alot better then LC, just helping against botrytis makes it worth my money. Thanks OG..+rep

That Eagle 20 is scary shit :

Exel LG is systemic, too, but much much safer

^^^^^^^ Yeah, I looked at the MSDS and it doesn't look any different that most other fungicides or pesticides...... or very much different than Exel LG either for that matter. The Eagle 20 says that skin contact merely causes irritation same as Exel LG. And that prolonged exposure is unlikely to cause absorption of anything harmful. It has low toxicity if swallowed even. That being said, it contains small amounts of Napthalene which has been labeled by the International Agency for Research on Cancer as a "possible carcinogenic substance" . The U.S. EPA has placed naphthalene in Group D: NOT classifiable as a carcinogen (U.S. EPA, 1994a). The International Agency for Research on Cancer has NOT classified naphthalene for its carcinogenicity (IARC, 1987a).
At worst, in some cases LARGE AMOUNTS of VERY PROLONGED EXPOSURE of a single trace ingredient (OVER 2 STRAIGHT YEARS OF NEARLY NON-STOP VAPOR EXPOSURE) caused SOME rats to exhibit evidence of carcinogenic activity. And we're talking pure Napthalene. Besides this, once in the atmosphere, naphthalene rapidly photodegrades (half-life 3-8 hr). And AGAIN, we're talking direct application of this chemical which Eagle 20 contains trace amounts of...... which cigarette smoke also contains.
Point being, you can get the stuff on your skin and in your eyes with mild irritation, you can drink the shit and not get ill..... just don't distill the napthalene out....... become a 3 ounce rat and huff it and bathe in it for two years.... or you could possibly get sick, lol. Point is, the stuff is perfectly acceptable to use in the vegetative plant state and probably in the first few weeks of flowering for that matter. Anything in it that could possibly be harmful is perfectly safe in trace amounts and perfectly safe since it rapidly breaks down as well. I can't say what works or not if I haven't tried it, but if you have fungal problems Eagle 20 can and will cure it with no messing around.

i'm 100% on my end past three year's in my area my harvest was cut by 50-60% of what it coulda been. I'm not trying to convince you though, maybe you didn't have it. Because believe me if you did you would know. I'm sure we can't the only people to have had leaf spot disease, i have seen it on alot plant's people have posted this year. It's mainly affecting the guerrilla grower which around here on RIU aren't that many.

are you not treating it.I can't seem to stop this disease!I tried picking the dead leaves off. I've given up on that, it seems they just fall off faster when I do. Time to let nature take its course. It's been a wet summer where i'm at. Ahhhhhhhhhhh

Well good luck man, hope it works out for ya. Was you treating before the disease appeared or afterwards.

I think the best to beat this disease is prevention from i have read. Are buddy OG is having great results with Eagle 20 this year. I have saved my year with the liquid copper i just wish i coulda found it before i lost so many. Strain selection may help but i hate for a disease to decide what strains i grow. And from what i have read it effect's everything, a guy i know had great luck with sensi star one year seemed resistant though he still treated for it. Following year sensi star was devastated by it so go figure, i'm going to try to get this up as a sticky for people to learn from. To many people are disregarding leaf spot and claiming def. of some sort or another. Maybe but it's to easy to treat for it rather then keep boosting your Nitrogen while your plant wither's away.
Personally, i will be using Eagle 20 next year around beginning of june and back off of it at the end of july and switch to liquid copper on my infected plants. Im waiting to see OG's report on if the eagle 20 help's with bud rot. But if im not mistaken he told me he's never had this problem.
