Looking for guerillas with leaf spot diease experience.

[D.S. Toker. MD]

Just a note.

I just got back from the first group of plants i treated and the results are clear.

1. The liquid copper is 100% effective on plants that either dont have the disease or are just getting it and have maybe 5-8 affected leaves. 1 dose seems to do it.

2. LC is 80-90% effective on plants that are actively involved with lots of yellow leaves. 2 applications are required here - a week apart. Not only does the yellowing slow dramatically, the plant looks healthier and green again.

3. LC is clearly effective, but plants that are fully involved with the disease and have many primary and secondary leaves yellowed, the disease is stopped but the ability of the plant to recover is limited to its state at the time it was sprayed. It turns green again and continues to grow, but the yeild is greatly reduced and the plant is damaged. 2 applications are needed here.

Its as clear as a bell that if i had treated the plants with Liquid Copper at the first sign of the disease, i wouldnt be in my current position, which is harvesting 5-7 fewer lbs of weed than i would have had i know about the LCopper.

I have another small group of buds im drying today to test for chemical/taste etc.

Hey guys. For what its worth, I have been harvesting autos grown outdoors since mid june. The first batch was started indoors. All the rest were direct seeded into pots and hidden amongst the weeds and flowers in my garden. I am growing tomatoes, which are the biggest blight magnets on earth, as well as all the other veggies. I have had autos in with Heliopsis, a type of yellow daisy that got PM back in June and has had it bad since. No PM on the autos. Whether it is the particular resistance of the autos, or the Serenade I have been spraying since early on, I can't say. Last year Serenade was ineffective on tomatoes. This year it seems to be working. I did shake some Rotenone/Copper on all my plants early on as well. I believe the key is early prevention. Once you have significant infection it is very difficult to overcome. This year the weather has been quite a challenge and has been a major contributor to problems. Excessive heat with low rainfall BUT high nighttime humidity was the real culprit. Then daytime rain and cloudy ultra high humidity set in. That and flowering I think has been the downfall here. In general gardening it is known that inconsistent watering leads to PM. For guerrilla gardeners it is so hard to manage water. Maybe the fast cycle of autos has outrun my disease exposure. I don't know. I don't run long season girls anymore. Good luck.

Thanks for the input its great to see something that works. I will have to get some Liquid Copper I need to know if it will control the leaf spot variety I have. As far as the serenade I have my doubts because of what Dorje said below and the fact Serenade is a systemic fungicide also.

Also... we used Eagle 20, a systemic fungicide used for PM, so that's another fungicide that doesn't seem to do anything.

The weather has become dry and the dew points are low so I really think that’s what’s slowed it down in my crop. I will not be able to give any feedback on Serenade for a couple of weeks. I used this before I don’t think it can cause burning like Green Cure can in a heavy dosage because all the flowers got heavily sprayed and I mean heavily.


I want to personally thank everyone who participated in this thread we all need to stick together to beat this disease. I hope everyone sticks around to give there results good or bad I have to believe its not over due the fact that we all know late September -October can be a cool rainy months.

 

[ghost of sage]

the liquid copper did it for me too.I didn't wait a week though.I put it on and two days later we had a rain and i put it on again and when I went yesterday which woulda been about a week it was gone.It definitely works!DS I am so glad you found this stuff because I had this crap at my second honey patch when I went to check this weekend and i was sick!!

 

[ghost of sage]

This is one of the first threads I have seen on IC where everyone came together to solve a serious problem and there wasn't alot of bickering and bitching and back biting and that is what it is all about!Very good thread here with a bunch of guys from all over coming together!

 

[Juan Valdez]

whats up people! I think this thread may have saved my ass this year, been dealing with this disease unknowingly for 3 yrs now and have lost many plants to it. it's practically on everything and anything in my county. the more I look around the more I see it, basically you cant find a plant or tree that isnt affected !

the past 2 years i always thought it was ph, bugs, nute def, burn marks from water droplets etc... this year i came to the conclusion that its very odd that my plants are all well and healthy each year throughout veg then right around begining august/first week flower they all start getting spots and leaves start to yellow prematurely. so i started searching around for answers on other sites and didnt really find much, until I came across this gem of a thread! been following since the first post!

went out to the site earlier to apply my second application of liquid copper, its been a week since the first, and things are lookin good! LC definately seems to help, I removed 90% of the affected leaves before the first application and today I saw very very few new spots and/or yellowing leaves, it was a HUGE relief! kinda like if your car breaks down and you gotta put it in the shop, the whole time your thinkin the worst, it's the tranny or head gasket or blown motor f$%k i'm gonna be out soo much money I cant afford this s#$t right now, then they call ya and say it was a couple of spark plugs, you can pick it up tonite, and your back up and rollin again !

that's how I felt today and wanted to say thanks to hamstring for starting this thread and everybody that contributed! you cant find better info about our plants and this disease than right here! THIS THREAD SHOULD BE STCKIED FOR SURE!

well i'm gonna stay tuned and will post some hopefully positive updates

goodluck everybody, stay safe. peace

and the fact Serenade is a systemic fungicide also.


Not to pick nits, but Serenade is definitely NOT a systemic fungicide. It is a biological control that uses a sporulating bacteria that colonizes plant surfaces and does not give competitor organisms a chance to become established. Thanks.

 

[Dorje113]

DS, I'm glad the copper is working. I am trying ferti-lome Broad Spectrum Fungicide (non-systemic) with chlorothalionil, which was consistently recommended for Septoria fungi.

If this does not work I will use the copper sulfate, I have been purposely avoiding it so far, started with organic, then the ferti-lome, next will be copper.

Prevention is also consistently recommended too, if you know you are growing in an area with this stuff present, you should use a fungicide as a preventative, liquid copper seems like the best bet but I'll report if the ferti-lome stuff works or not.

Indoors.... don't be a slob and keep your place clean. Don't allow unhealthy growth, pick dead fan leaves and keep the moms pruned and trimmed of excess foliage.

Hey brother take a look at this link about serenade and let me know what you think (listen close to the ending) this is where I got my info. Not exactly sure but systemic action is mentioned but maybe not directly I will let you make up your own mind. Definitely no expert just a old guerrilla due diligence is a must so thanks for the feedback.

DS:My spots aren't as blotchy as yours, mine are smaller, say bb size, and they make crispy holes in the leaves. I'd already hit her with micronutes and calmag 3 weeks ago just in case, and it didn't help, so I am positive this is a fungus. Holes are too big to be from mites, and there ain't no mites anyway, no webs - I looked with my microscope all over. It spread from bottom to top pretty quick. It is starting to get holes in all the leaves, but since this one is in 7th week of flower, I decided to let her go one more week and chop, and not spray anything. You think this will be OK?

This is my only infected plant, my last WW - because all the others were killed by deer and hogs!

One thought I had was this came from using leaf litter raked up from the area for a natural-looking mulch. I mulched about the same time the weather got hot and humid. Maybe that's a cause...

Also I have decided there are other strains that would probably work far better in this climate, so no more of these seeds (GHS Fem WW) for me. The Haw Snow have not one spot on them, and are growing fabulously in the heat. Only one has started flowering, so they have many weeks to go yet.

 

[whodair]

see spots on surrounding vegetation ?

but overall i think i'm gonna survive this with no treatment

as they start pouring on the resin im hopin for some natural immunity to occur ....

 

[Finepointcanon]

This one has spider mites... I'm assuming that 's what's causing these spots and not leaf spot disease. (??)

That’s the shit all right but your spots are all small that’s how they start out. Looks like you haven’t had much rain or humidity lately. I can live with those that’s when I discovered mine and sprayed with green cure. Didn’t help the next 3.5 weeks was rainy but even worse so hot and humid you could cut it with a knife.

I would go with the liquid copper DS says it works. Might be a good preventive measure because any water and those spots start growing and running together. Take a look at my picks if you want to see what can happen.

Thanks for posting the pics and Good luck to you

dont wait!!!

Don't chance it whodaire that shit moves so fast you won't believe it!It can go from that to half the bottom being yellow the next time you go!It looks like you have at least 6 or 7 weeks left ytou better put the liquid copper to them now!

 

[D.S. Toker. MD]

ghost is right, the shit is quick. Nice plant ghost!

If the plants in those pictures are treated they will be fine and you probably wont have to treat but 1x.

Ive smoked 2 groups of bud from sprayed plants and i cant taste anything bad or chemically, but i worry a little. Most of the safety data for these chemicals come from the manufacturer. They have every incentive to report that everything's great, and zero incentive to tell you about the few male subjects that started growing tits and a pussy.


Im washing mine. Liquid Copper is highly water soluble. After youve trimmed the bud, give them a 15 minute soak and any potential residue will disolve and be removed from the plant. This gentle soak doesnt effect potency or any other aspect of the weed in any way.. THC isnt water soluble, liquid copper is. Trim it, soak it, dry it, jar it.

Here's an oz soaking. Strain with the spaghetti strainer and dry

New grower with leaf spot

New grower with leaf spot

Hi all. This thread is awesome....so much info that has been helpful. It appears that we have the same disease that we are seeing on all your pics. We had to pull one plant cuz it was just destroyed by this crap. A friend brought over a fungicide called "Bonide Fung-onil" for us to use. After reading the info on it we are a bit concerned. On this product as well as the Liquid Copper it stresses caution during application...like be sure to not get it in your eyes, on your skin, inhale it, etc.. So do we need to go out and get a bio-hazard suit to apply this stuff? Really would like to hear how you all apply these things safely. Thanks so much for any and all advice
