Whats the best product for botrytis leaf blight?

[AmsterdamLiving]

I wouldn't wish this shit on my worst enemy. Well thats a lie but this shit sucksssssssssss.

Im using GreenCure but it seems to be BARELY slowing it down but the bacteria overcomes it easily.

I got this fungicide called Chipco 26019 n/g and its supposed to be the best. Well....it is for ORNAMENTALS! Do you guys think I could use it for the plants in veg? Im not going near it with the ones in flower. The stuff cost me 100 dollars

But I need something else, something I can use on flowering plants and veg plants. Something that can be used on plants with "fruiting" properties.

GREENCURE SUCKS FOR BOTRYTIS LEAF BLIGHT!!!!!

Blight is a bitch. I was unaware it could affect MJ. Finding a safe solution for a flowering plant will be difficult. does it look like this:

 

[Kiffen]

Blight, spider mites, and caterpillars are all terrorist as far as I'm concerned.

 

[bicyclebenny]

I've used Consan Triple Action 20, but not during flowering as it's not listed for consumables. It kills all fungus in one shot. Physan 20 does the same and is also not EPA approved for vegetables. So you must decide...

 

[Chiefsmokingbud]

Yeah once you get it you need to disinfect after you get rid of it.

 

[bicyclebenny]

I just noticed that Daconil is at Lowe's for $8. It is listed for veggies.

 

[Moldy Dreads]

Botrytis as in Bud rot grey mold or some kind of leaf issue? Please clarify...

 

[buzzmobile]

I would suggest looking into Serenade. Good luck with the curse you are fighting.

 

[Bumble Buddy]

The best product for botrytis? A dehumidifier and/or a fan.

Interestingly, botrytis outbreaks is desirable in some wine-making, referred to as "noble rot"

Botrytis cinerea is the asexual, spore-forming form of Botryotinia fuckeliana (you can't make this stuff up).

Quadris is approved for use on Tobacco and has xylem mobile systemic activity.
I know a woman in Florida who uses it on roses and orchids and says it's a miracle product.

http://www.syngentacropprotection.com/prodrender/index.aspx?prodid=413

It is based on azoxystrobin, the active ingredient of the pinecone mushroom

http://www.dovebugs.co.uk/Strobilurin%20fungicides.pdf

Depending on what continent you live on in europe it's Aspire in the us it's Heritage. They all have the same active ingredient.
It is both a preventive and curative fungicide and can be applied the day of harvest!

 

[crippled1]

Here's another product that is used to control botrytis on grapes. I hear it is very effective, it is also organic and leaves no residue at all.

botrytis murderer was just the working name, it's now called
Botrytis Control.

chiefsmokingbud: ya a little bit. i've had this problem ever since my first veg in a perpetual op. Im definitely bleaching the walls/ceiling and anything else i need to have in the rooms.

bicycle benny: When I found this PDF... http://www.chasehorticulturalresearch.com/pdfs/pro-botrytis.pdf Chipco was the cheapest i found but if they got it at lowes for 8 bucks I might finally be able to get rid of this awful scourge that is aiming to destroy my precious newly rooted clones and wreak havoc on my girls in bloom.

moldy dreads: as i am into 3 and a half weeks of flower I have yet to see a problem on the buds.........yet. Just the leaves and the stems left over after I clip a diseased leaf.

buzzmobile: thank you for that i need all the support I can get.

Bumble buddy: ya man good looking out I've been running my dehumidifier ever since I learned they thrive in humid environments. Since it has been running I haven't been running fans but one day I ran 2. One blowing through the bottom stalks and one blowing over the plants under the lights(they are trees). The next day I walked in and it was EVERYWHERE!!!!! i was like holy shhhhh, im never doing that again.

If this daconil doesn't work(lets hope that it does) i'll be looking into serenade and Quadris.

I'll report my findings when I can. I'll take pictures of the diseased leaves as well. thank you all

Chlorothalonil (Daconil) is classified as a probable carcinogen, it MAY be ok to ingest it but definately not to smoke it.
You might want to read this before using it on cannabis.
Scary shit

http://www.pesticide.org/chlorothalonil.pdf

You should really go with the Quadris, it is approved for tobacco. Do you realize the significance of this?
It is meant to be used on crops that are going to be smoked!
I have not found one other fungicide that can say that.

 

[crippled1]

Chlorothalonil is contaminated during
its manufacture with hexachlorobenzene.​

65

Hexachlorobenzene

(which was itself used as a pesticide until
all uses were cancelled in 1984) is classified
by EPA as a probable human carcinogen,
like chlorothalonil, because it
causes liver, kidney, and thyroid tumors
in rats, mice, and hamsters.​

​

29 It also causes

a wide spectrum of other adverse health
effects: impaired immune system function,
porphyria, kidney damage, effects
on the thyroid, tremors, and reduced fertility.
Hexachlorobenzene bioaccumulates
in both animals and plants and is persistent,
with a half-life in soils of between 3​

and 6 years.66

Are we talking pm here?Or is this totally different?

 

[crippled1]

Powdery Mildew is something totally different. Botrytis is usually the biggest problem during late flowering. It can take out your entire crop very quickly.

Bumble Buddy:L M F A O!!!!!!!! ahah. This daconil stuff looks like sperm!!!! I just done spraying my lil veg plants and now they look like they just got done wrapping up a scene of some bukkake movie.

Moldy Dreads: The grey mold botrytis. Its tearing my leaves to shreds! Not literally of course. I was snooping around in there last night and I did see it overtaking a micro-bud. Also it seems to be latching on to the tips of the pistils or whatever the while hair is called on the top of the bud. A saw a few buds with THIS on my worst plant. I don't know how I'm going to stop it from eating the buds like a flesh eating virus. On the worst plant there are hardly any leaves left at all as it is and I still got another month plus before chop chop time. OMG! I don't to lose a whole damn plant... Not on my watch dammit!!!!! If anything that plant is getting the Daconil. I haven't decided on the 3 other ones. It seems I got a lot of leaf left for the disease to eat before it reaches the buds.

jiggywhompus: I should have lots of good pics in a couple days

crippled1: Daconil is definitely nasty. But I plan on using it for the ones in veg and on one plant in flower. We'll see how it goes. After chop i'll seperate the daconil treated buds apart from the others and see if I notice a difference. I know I shouldn't use it for the one on bloom but my hands are virtually tied. Drastic times call for drastic measures. that sort of thing. If I can save most or even half of the plant it will be a win... shit anything at all practically because at the rate its moving on the most sickly one its only a matter of time before 80% is destroyed.

I don't really have a choice. If I did I would but I don't. I blame the government mostly for putting people in these kind of positions. They did not manufacture the botrytis but if was legal many years ago they're would be info galore on how to deal with this.. research and all of that. But now it seems I have to employ a trial and error experiment that wouldn't be necessary if MJ was legal many years ago. So we're basically living in the dark ages when dealing with Botrytis on our beloved MJ. Yeah this chem is toxic and cancer causing but...... im going for it. Hope for me a fast death!!!!

 

[Clackamas Coot]

So this is a problem that will affect vegging plants and attack the foliage?

I would love some pics of this problem.

jiggywhompus

This link should give you an idea on how much damage that this fungus can cause.

Part of the problem for gardeners is that 'blight' continues to live in the soil meaning that unless you move your garden you'll be dealing with it next year and the year after, etc.

Not much good news - most of the tomato crops in the Northeast (USA) was wiped out this year. Even the NY Times chimed in with an article on blight.
