Fusarium, My Experience

[fearnoevil]

Btw, that article linked to the study of a type of Fusarium that causes nail fungus is scary - to think the same pathogen can spread from human to cannabis is just plain bad news.

Dude this guy is deluded, Vostock says it best, Fusarium my ass

 

[fearnoevil]

Fighting Fusarium for three years omg !!!!!

I don't think it's Fusarium that's causing the blight disease, I think it's possibly a species of Botrytis, same or related to what causes bud rot, although I'm leaning towards it being a different one because, while not proof, I've rarely had bud rot issues, even when the blight returns in the last weeks of flower.

That's happened twice, after I've stopped applying Serenade, and then it's just an ongoing battle of cutting off any leaf that shows signs of it - the last time I ended up pretty much completely defoliating the some of my plants, which definitely had a negative effect on quality, but after the chop I couldn't find any sign at all that any of the flowers had been infected.

Us growers who have grown a while are simply scratching our heads to this whole thread, 3 years fighting fusarium is just misguided bad growing. I dont step up and slander much but you either believe this guy or you believe us when we say bs.

Spreading myth, bad info and who da funk takes on fusarium for 3 years with zero proof they can actually grow.

Lets seperate the wheat from the chaff and draw a line in the dirt, im on the growers who have commented bs, fusarium is everywhere and so is fungi and bacteria, you really have to be a special kind to be culturing it instead of mary jane. Newbie forum is where this should be and i dont care what peeps think as some are too fickle to ignore and hump this stuff till their convinced.

Biology not brology, word out...

Well if you read the article it states that while not common, they may be an opportunistic pathogen which enters via an existing injury.

Among the causal agents of non-dermatophytic onychomycosis, a number of Fusarium species viz., F. solani, F. oxysporum, F. proliferatum and F. moniliforme have been reported. [2]

Notibly F.oxysporum is a known cause of Fusarium in cannabis, so it's worth noting this. From what I gleaned, it seems the more you handle various soils and organic amendments, the more likely you are to come in contact with these pathogens, ergo organic farmers beware, make sure you wash your hands well and don't go barefoot in your garden.

I'm not going to argue with you Kingrow1, because it's becoming increasingly obvious that you aren't actually reading, or at least comprehending, what I've written. I SAID it's not Fusarium that I'm dealing with, and I would remind you that YOU don't know everything there is to know on the subject of cannabis pathogens.

I've been growing MJ longer than you've been alive, since the mid 70's, started up in Wasilla, Alaska growing the original Matanuska Thunderfuck given to some friends of mine by the original breeders. Since then I've grown, on and off, for about 20 years, and I've seen more and have more XP than a lot of peeps on RIU, including you I'm fairly certain judging by your lack of knowledge, so before you go spouting off about spreading myths, maybe you should step back and check yourself and your ego Bubba.

But none so blind as those who will not see, and I'm certain you'll learn nothing from this conversation, so I'll not waste my breath. Suffice it to say, if you think you're some kind of professional botanist who knows everything there is to know about the pathogens that cannabis is susceptible to, then I'm all ears, otherwise just keep your uniformed op to yourself.

Id love to quote the science to it but lets just say that this is rare and happens through bad practice, other fungi and bacteria keep it in check. All this has been said in the thread and Vostok has stated himself as i and others.

Ignore and grow on, until your tent is infested and weak death looking plants just ignore.

I believe I had it but I managed to get it under control with a heavy dose of Bacillus subtilis, and introducing Glomus intradices to freshly rooted clones and the use of a fungus and bactria laden worm bin. Took about 4 months after figuring out what was going on to getting back on track. It pops up on weak plants time to time now but I believe it has been out competed by all the other action going on in my dirt. Also it definately is a type of foot fungus. I am possitive that is how it got into my room. Foot fungus is gone too now BTW.

I think the root of the problem is cleaning practices. Nature hates a vacuum

I believe Glomulus Intra how ever the fuck itams spelt is all wedd needs, one of the most common fungi in soil so no need to add unless you killed it off in the first place, which is probably the point at which the bad stuff got hold.

I know this science too much but dont tell all those chucking money at all those other benies or they might just save a ton of cash.

Also the fungi that 70% of the worlds plants rely on for their survival and uptake in soil.

Most info available on Wiki, The Cap milked it all and made a ton of cash

True that, but GI grows slowly and only really blooms and thrives on roots , also it can be quickly overwelmed by other fungi and most bacterias.

That makes sense, although it is weird and maybe hard for some to believe, there are some things, especially fungi, that could jump the animal plant divide. The article does say that it may be opportunistic, needing an injury or other entry point to be able to get started, but as much as we expose ourselves to the potential as we constantly tend our girls, I suppose the odds increase.

But in my opinion it's not likely to be the most common vector of these types of infections as spores can easily spread and hide throughout a grow room, building or home creating a cycle of reinfecting grow after grow.

 

[Kingrow1]

Stuffs thrived since it first split from the evolutionary branch, otherwise it wouldnt be so highly established everywhere.

Like peeps can believe what they want im just a simple man who can take it at face value, probably grows at the same speed as roots and only the tip of the root is where it needs be.

I digress, goid luck

Here is a fungus hack for anyone that has made it this far into this thread.
What to make a big colony of GI?
Buy a source with only GI as the active ingredient
fill a tray with about an inch of peat, don't bother sterilizing
take some waste stocks from a previous grow and cut them up into about 1-inch sections
spread them on top of the soil
sprinkle your GI all over the stocks and moisten generously with spray water
completely cover with more peat and spray the top.
Keep it moist out of direct light and warm
Shortly you will have GI inoculated stocks that you can stick in the dirt near new roots

So before this gets too old, I came by to suggest thymol from thyme oil not so much as a killer of fusarium but it will hold it back. Thyme is a contact killer for many pathogens. I use it in my outdoor garden. Fusarium is reduced 80% in petri dish testing from the papers I have read on the net. On thing about a lot of these fungi is that they infest the trees and plants all around us. It has to be a tight room with serious entry procedures to keep it out.

This thread is too old, it keeps on surfacing for some innate reason....!

Sounds like renting an ozone generator and blasting that room would have been quicker.

 

[hybridcheef]

can you use regular mycos with mycostop? and actinovate?

 

[Kingrow1]

Probably....

Why bother with mycos in the first place, most of this stuff is everywhere and pretty invasive on anything that contains anything that can break down into a nutrient.

ok, almost one year has past since my last post, i haven't bin on it all that time, its around 3 years since the war has started and fusarium still hold the line, at the moment i am in a environmental and personal growing behaviour reform, 90% of equipment thrown to garbage, as well as many other personal belongings and "stuff" i got, the whole house is about disinfect in a VERY sufficient way (99%) TWICE with EVERYTHING i own in it, so as the car, if i could id leave my two cats inside the house while doing it but i lovem alive.
the room will be totally empty when planting, nothing unneeded stays, any tool come in contact with the new clones and their soil will be new, in fact, all ill need from my old equipment is a light source, not even the ac will work, no blowers, nothing other then a bold reflector and ballast which will be sterilised a few times, with the whole house and alone, beside that, ill have a few new biocontrol agents and chems agents, ill do 11 clones each with his own mixture, ill be having:
bios:
root shield
mycostop
actinovate
serenade(cease)
companion
prestop
and one with all together

chems:
folicur (tebuconazole)
scholar 230sc (fluidioxonil)
sportak (prochloraz)

chems are going all together in two doses
another clone with low dose chems + all bios
another clone with no chems nor bios, only water and nuts

coco coir perlight 50/50

if this fail, I'm throwing the white towel, will update in a week or two, wish me luck, ill need it.

I know this post is a couple years old but just curious on how results turned out? Currently fighting a never ending bout with Fusarium myself unfortunately.

Results were this guy was a dick and this thread the worst.

It wasnt even fusarium - now let this thread die
