Guerrilla grower's nightmare Leaf spot disease

Good to hear 1BMM, yea ima keep this thread bumped, cause i read on here 10x but if your growing outside in the brush a week people wondering why there leaves are falling off and dying. And they always get the same answer from people, check your ph or give more N. Which may be the case but if your growing outside or even in the corner of your yard odd's are your dealing with this bitch of a disease. But the liquid copper will keep her at bay and works great as a preventive.

Seen sannie's herijuana strain. It looks alot like the medijuana strain from amsterdam seeds

I'm happy with what i've gotten from Sannie. The only thing is that there all so similar. The buds on my outdoor plants smell and look better than my indoor ones did. The trichomes on everything outside is much whiter. Hoping that means stronger Also, the strains that produced bananas indoors doesn't seem to be doing it outside. I love growing um under the sun!

good to hear tennis.

The later stage of this dreaded fungal infection. This is on a blueberry plant from bagseed.

This isn't new news for RUI. I had this happen last year and found somebody here advocating the copper spray and the whole bit. He was quite adamant that everybody hear about it, and was probably getting the same "it's N def" replies, which was why he was so strident and all.

But I didn't do anything about it last year, though considered using copper spray, but they were flowering so I didn't. And actually, the fungus seemed to go away after an alarming few weeks of leaf yellowing and loss. Everything in the bush also showed signs of it.

This year, nothing. Last year's strain was Arjan Haze 3 (bad idea for my grow zone), and this year its Querkle. For what it's worth.

There is no doubt that introducing anything new into an ecosystem can have unintended consiquences. The thing is about animal testing etc. (which I
am vehamently against) they are exposed to exessive amounts of the product tested. Let's face it, we are exposed to cancer causing chemicals constantly.
Take a look at the back of your toothpaste sometime. If a child decides to swallow the toothpaste he/she is using poison control should be called immediately.
Flouride is a cancer causing agent when a person uses more than is recomended. Let's face it, we risk death walking out the door in the morning. Doesn't
mean I don't look out the door before I go but I don't want to stay in my house all the time. It's important for good folks like you to keep people aware of things
like this though because most people wouldn't think twice about using a product to protect their crop.

I *think* you are agreeing with me there, not sure tho......either way my whole point about all of this is that we need to have an accurate understanding of what the dangers are about anything we do. I am definitely not shouting that the sky is falling, but we have to be open to hear the things we don't want to hear, if we are actually going to have a true grasp of the dangers of anything. I think people are so often so eager to have someone say "just use this one product, and all your worries are gone" that they start looking to poke holes in the statements of anybody that threatens their belief that the magic product is less than the ideal thing they think it is.

Another way to state my stance on the Eagle 20/Exel LG thing is that it is a shortcut, and for the price of more toxicity, you get a potential for an easier way out of a particular issue. It is undeniabley more toxic, and to me, unacceptably so.

btw, I know EXACTLY what is in EVERY thing I put in or on my body.. I had a major wake up call in my life. It's actually related to the reason I ended up on these boards.

Foilar spray, and than I also spray the surrounding vegetation and the surface soil, but I do not drench as I am not sure what the copper would do if concentrated in the soil from a drench.

Remember, dont be afraid to be liberal in your application. I have soaked my plants with 2-3 ounces per gallon of this stuff and the plants were fine, although I since most of stuff will done in three weeks I wont be doing any more spraying.

I just checked the LG label right before I sprayed (btw my 40 oz hydrofarm pressure sprayer is the fuckin bomb, link).

Anyway, I found out that theres no copper in LG. Not sure if that would affect your decision to drench or not... I ask because I am considering using it for a drench, but don't know if it will kill all my beneficial microbeasties.

I could not agree more about starting all treatments early. For all intents and purposes, all my questions and shit are so I can be really ready for next year, adn I want to have a plan in place before I go out.

As far as using it as a foliar, your comment regarding copper makes me wonder if I could add copper spray concentrate to the LG to increase it's effectiveness.

I am also considering using Messenger link , which seems to increase the plants growth rate and activity of it's defense systems at the same time, which is a nice side benefit. Maybe I could mix all 3 together, and get them all sprayed on in one shot.

I would like to do some tests on indoor plants before the outdoor season to see how the plants react to the foliar cocktail, but am open to adding other things to it or taking them out as is appropriate...any thoughts on additions or subtractions form the cocktail?

I am also working on a soil treatment plan, too... maybe I should start a new thread to keep that whole thing clean and focused? Thoughts on that?

hey steam, it appears this issue has a lot to do with humidity levels. Do you remember if the humidity was generally higher when the problem was manifesting?

and sorry tristynhawk for hijacking your thread, man.

The worst leaf of my infected Blueberry. This plant has very little resistance to this fungus.

hey steam, it appears this issue has a lot to do with humidity levels. Do you remember if the humidity was generally higher when the problem was manifesting?

Last year was more rainy/humid than this, but where I am, this year has been the absolute perfect summer (sunny every day, and only rained in the evening or early morning), so it's hard to compare.

So last year was more humid/rainy than this, but not exceptionally so. I just kept pulling all the yellow/pitted leaves off when they appeared and it stopped.

I do fear that everybody with a yellowing, pitted leaf or two is now going to start hosing down their crop with copper spray. We can be an overly-worried bunch come flowering time, us growers. Fungus is not good, but these plants do naturally exhibit yellowing/spotting of leaves as they flower. Essentially, your plant is eating itself, and that's never pretty.

i don't really consider it my thread don't worry my man. It's a thread for the community as a whole IMO. I'd like for everyone who deals with the disease to post their treatments and outcomes is what i'd like so we could all benefit.

this disease hit's in early june and so on, plants should not be yellowing at this time of the year. It's early sept. and my plants are still a dark green i haven't had any sign of the disease in weeks, ever since i started treatments i havent had any yellow leaves at all. But yes i will be drenching my plants every year from now on starting june 1st. I see no reason not to, i don't want to wait until my plant is infected. I'm going to get a pound a plant on quite a few of my girl's and if i wouldn't of sprayed it would be significantly less.

^^^^^^^ 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.

kind of hard to us proper amount spraying your plants. double spray a branch and its dead. miss one its dead. plus your adding mosture to the buds.

Click to expand...

Ive only read half the 1st page & had to stop.

Dude you are out of control with your speculation & accusatory exclaimations that you OBVIOUSLY HAVE ZERO HANDS ON EXPERIENCE WITH.

IMO posts such as yours are the absolute worst of what happens in an advice forum,some clown comes along with his "beliefs" & at all costs must be right,then continues posting nonsense just for the sake of posting.

Let me clear up some of your misconceptions & fear mongering.

1 You= your delievering moisture to the bud.

Duh ! Water is the delievery agent that carrys microscopic copper particles to all areas,most importantly areas in the bud.

2= You,its kinda hard to use proper amounts spraying your plants.

Are you serious,a 6 year old kid understands the concept of spraying liberaly from the top down.

3 You = double spray a branch & its dead.

Complete bullshit & 100% unfounded,you could douse an entire plant in it 5 times & it wouldnt kill it,not even have one sign of distress as long as its all in the same application & not in mid day sun.

4=You Miss a spot & its dead.

Again complete jibberesh,any spot you miss simply dies off but cant transmit or exchange the virus to other leaves,HELLO !.they have been treated,explain exactly how the fungus can attach itself to a surface treated with the Copper Octanoate mixture.

You obviously have no experience with the nature of this product,how it works,how it reacts to plant matter ect so you should stop screaming danger will robinson,potentialy stopping a grower from using a product,that if used even half ass properly will save their crop.

For those of you actualy listening to this guy & are afraid to use Copper Octanoate treatments for fear of hurting the plant dont worry,Copper Octanoate is actualy a soap,it is water soluable & only stays on the plant surface,also from my experience with using copper soaps the leaves do not take in harmfull amounts of copper unless you go bezerk & treat the plant many multiple treatments,letting the copper soap build up on the plant.

Even then one light ran & it all washes off.
