Fungal disinfection

Very nice results, I admire the thoroughness of sending off for confirmation.
 
THE RESULTS ARE IN!!!... what the fuck?!

THE RESULTS ARE IN!!!... what the fuck?!

Attached is what i received from the plant pathology clinic.

Looks like i had a double team from rhizoctonia and... cylindrocarpon!? Never had heard of it and can't find all that much info on it. What i did find was that glomus intraradices 501 is the best bio control i could find. Captan seems like a good chemical control but it will hurt my mycos. I couldn't find much mention at all of this fungus on cannabis, likely why this had been so hard to figure out. What i did find was about wine vines, which there are many of those in my area.

So... seems like my plan of action should change a little. I'd like to hear some ideas. Should i sterilize for a bit and start with Captan until i have decent roots, then cease and start glomus treatment? Go glomus alone? I guess i might be a pioneer in this one. Hooray, i guess.

If i go Captan then I'd have to use another chemical for rhizoctonia.

Thanks for everyone's attention. I hope this has been educational at the least. Perhaps the first report of this on icmag? Big thanks to everyone!

The type of special that gets you on the small bus.

I see two paths. Conventional control followed by remediative steps (tea, inocculants, etc).

Organic control through Trichoderma (Rootshield), followed by above remediative.

Now that you're on this testing hullybaloo, what about both (if there is a body of plants of equal size/health) split down the middle with a sacrificial control? Quantified anecdotally or other wise.

Just sharing thoughts as I think this will be interesting.

Not having a healthy biology/ecosystem may have gotten you here in the firstplace. Why further damage your ecosystem with conventional warfare? You'll just be dealing with more and more pathogens.

You're at a fork in the road.
The path to the left is using chemicals and growing in a hermetic bubble.
The path to the right is working symbiotically with nature to keep your garden healthy and happy.

Chose well,
Peace
 
Well I definitely want to use some sort of surface fungicides on all my shit and get rid of anything easily replaceable. And heat treat the room and equipment (what's a good temp for that?). I think using no chemicals at all ever is a bad idea; gotta sterilize equipment between runs with good surface fungicides like bleach, physan, h202, or this DDAC stuff I'll be using for this project. Couldn't i then split the fork and use conventional soil fungicides to start and then when i am comfortable that there is likely very little spawn capability i can add back the bios after some flushing and waiting? Sure I'll be sending plenty of microhelpers to their death initially, but eventually i'll have a healthy biosphere.

This all started in july of 2014 when a dude who was my partner decided to pull the a/c from the veg room and put it in the house. It was like that for 2 weeks while i was away. I'm guessing the average temp was in the 90's and there was an open reservoir in the room. Since then I've changed everything about the grow. He was Mr. Money and didn't like to listen to my advice. When it was clear i wanted him out he kinda fucked me over :(

I grow in wine country and judging by what I've read about cylindrocarpon it likely followed him in with some dirt from outside. Then with the environment like that it just spawned like crazy all over the equipment.

I'm honestly just really glad this wasnt a virus.

Either way, I'm going to use beneficials no matter what. I don't feel i need to choose; i should be able to clear almost everything microscopic out and start the biome over with tons of inoculate.

I think a test would be great. Not sure how scientific i am willing to make it but I'd say i have 6 plants i can mess with. These would likely all be new clones from an outside source. I can do 2 chem>bio, 2 bio>bio and 2 control. I'll figure out what I'm going to use, any input is helpful.

Thanks!

one of the nasties listed in the report is leaf septoria.... leaf spot.
I got this last summer,
a member here, crusader rabbit maybe?? recommended actinovate, a biological fungicide.
used as a spray and a root drench for systemic it seemed to knock it down a lot but not out completely
It's still been dogging me since.
I use E20 a month ago
now I'm finally seeing plants entirely free of this sh*t.
edit:i'm not free from this sh*t
btw,
one of the things to use to clean the gro rooms is trinity tr bombs,
kills all fungal spores.
its used in commercial greenhouses with plants.
I won't use it on plants but it will wipe out spores in your gro environment

hey fetchy,
here's more info for ya i have screwing leaf septoria since last aug but it's always bouncing back in one way or another.
doing more investigating and talking with bio works there a fungal and bacterial leaf septoria...

i didn't see any distinction in your lab report.

btw cleaning out all infected leaves goes a long ways to
fight this stuff,
I cull any leaves on the plants at the 1st sign and it's helped a lot.

check out Bio Works--> Cease and milstop
they have fungal and bacterial controls.
these are the people that make root shield.

i thought fusarium wilt was a soil disease, from every text book i have read its not something that exists outside of soil?

Cease and Serenade appear to be the same thing. I have ordered "Companion" which is a slightly different strain of Bacillus Subtilis that apparently is better in soil, so would be a better choice for me, but I have also been using Serenade up top.

Here's a bad update.

I sprouted seeds in peat pellets, popped real quick with no problems seemingly. I did this mostly for shits/giggles while I was sprouting some dynamic accumulators like comfrey, stinging nettles, and asparagus fern.

I inoculated the pellets with b. amyloliquefasciens, b. subtilis, g.(or R now) intraradices, trichoderma, and gliocladium just to be safe. All of these should be preventing these fungal infections.

They lasted about a week standing up before they almost all fell over and look pinched @ the soil line. I am pretty certain that is "damping off"

I used brand new products, brand new soil, didn't use any fertilizer, didn't use any kinds of trickery... I planted these in my house in my bathroom which is in a separate building than my grow that I had just cleaned with bleach. Made sure not to touch things in my grow and go into that room :( :( :( :( :( Even my stinging nettles are falling over and my comfrey has kinda stopped growing. Asparagus fern doesn't seem affected and has fat, wooly white roots coming out of its peat.

How is this still following me?!?!? I'll keep updating on what I do with systemic fungicides and see how that goes. I'll be lighting shit up with trinity as well.

Sorry to hear that.
Yup, I was fighting dampening-off for a couple runs after my Fusarium Oxy episode.
Modern Microbes was the simplest answer. Mix into your soil and use as a drench when germinating, then foliar with it.

l.


the biggest positive for damp off thrive is stagnant non-air movement.
captan mixed with water knocks it down.
a small fan will does the trick for me,
it doesn't have to be blowing very hard and the fungi can't grow.
although once my seedlings are a few wks old I like to have a fair breeze running under my HO T5s making the stems a lot more resilient PLUS keeps the heat off the leaves letting me get the bulbs down to a few 2-3 inches from the canopy.
this gets crazy node stacking that's impressive as sh*t.
