Fungus Gnats

[Crusader Rabbit]

Bought 195g of Gnatrol (Bt) recently from BGH. Using it on osha plants in one gallon containers of soil to knock down a fungus gnat problem. Didn't do a damned thing. In fact the little buggers are thriving. Maybe it was an old batch. Mosquito Dunks worked better than this for me.

Microbelift BMC

My mantra

 

[Sativan]

I read about this & tried it a few weeks ago w one watering... it suppressed Fungus Gnats for a few weeks & now they're beginning to repoplate the veg area.

Mix 4 to 1 water & H2O2 and water with that several times.

The H2O2 will destroy the fungus gnats, larve & eggs via oxidation. Not only that but the reaction leaves the soil rich with Oxygen.

Be sure to use a good living tea to replace any bennies that got oxidized too.

But what about my microbes? Won't the oxidation kill them?

I have to pull the plants because I'm going out of town for 12 days. I can't risk someone from the building maitenance crew coming in my apartment while I'm out of town.

I got busted two years ago for growing & possession (2 lbs) and I'm not going through that again. I hope the gnats leave since they won't have a food source.

Shit that sucks. Better luck on the next round.

my area just has an insane amount of gnats (lotsa water) nothing will keep em killed, so i just make my pots uneasy to live in, by 'sealing' the top with dry material, perlite, fine sand, dried grinded coco even worked

theyre annoying but dont harm mature plants

The high dose a few times has worked way better than the dunks ever did for me. Anything less is for maintenance afterwards.

Beneficial nematodes wipe out fungus gnats

 

[Arf]

I have read that a folar spray of neem oil gets into the plant and in is consumed by the gnat larvae, making their digestive system fail and they die.

I haven't tried neem oil myself yet, it's probably worth doing some research into.
My solution to gnats is cover the top of the hempy pots so the adults can't get in easily.

The active ingredient in neem oil is azadirachtin. It is systemic to the plant but I wouldn't bother with doing it via foliar application for fungus gnats. Instead emulsify it with some yucca, aloe, and silica if you have those or just some mild dish soap and run that through as a root drench. It will help kill off the fungus gnat larvae and the azadirachtin will systemically get in the plant. I wouldn't do this if you have less than a month til harvest though. Doing this neem oil root drench will also kill any beneficial soil mites you might have have though so be wary of that as they are helping you out.

Regardless,

Y'all quit playing around and get some Microbelift BMC and use it! The stuff is 16 bucks and lasts a long time. I'll keep saying this as long as it takes haha. Fungus Gnats are chumps, very easy to get rid of. Remember to get some yellow sticky traps up too to catch adults.

calls all the simple tried and true methods "dumb shit" proceeds to sell you nematodes. lulz.


anyway dude, like GMT said the simplest solution is to let the top half inch stay dry longer. water from the bottom or down the sides for a week or so. they will die. alternatively, like someone else said cover the top of your coco with something that stays dry, some sory of mulching material.

also you can skip all those yellow cards and sticky traps. the adult fliers aren't the problem it's the larvae you can't see in the soil eating your roots to shit. if you have a few plants then you can cut a potato or other very starchy tuber (root vegetable) into wedges and push the wedges into the soil/coco remove after 48 hours and or replace. the potato is more nutrition than your roots and will attract the larvae. pluck out wedge and toss. you just eliminated like 50%-75% of your attackers.

neem oil isn't going to be effective against gnats though, that was the one valid thing this guy did say. you can buy some mosquito dunks. buy the smallest package you can, you won't need much for long. just float one in a tank of water and use that as your water for your nutes. in a week or 2 you should see no more.

but basically. gnat life cycle is 7 days from larvae to adult. if you can keep the top of your coco from being wet for 7-10 days you will have no more. top dress(even just a layer of decoration rocks/glass marbles), water less often or from bottom if you just can't get it together you could always go with the bti (mosquito dunks) or buy some nematodes from this guy. i dunno wtf nematodes are going to do i have 0 experience. but i do know all the other shit works from experience.

I kill gnats the same way all the time...I use steam.
I have a Iron with steam function and a Wallpaper remover...whatever's closest.
I had a decent swarm going a couple weeks ago and blasted the top of soil with steam once then layed off the H20.
They're gone....usually I hit them a second time 2 days later.Once was enough..Eradication

I have been doing it for years.

Found a great price on Microbelift BMC at Webb's Water Gardens.

I can't find the report, but oregon, the state did a test on MYCO products.

Off shelf shit like OGTEA and OBGIOWAR, and stuff from lines, like piranha.

The test was for spore counts. For instance if you look at Great White from plant success they claim so many spores per gram.

Oregon tested that and found quite alarming results.

Most off the shelf products contained no spores or 1/32nd the amount advertised.

I recommend you don't take the lazy, expensive, uneducated route.

People don't realize that so many companies are taking advantage of them, selling snake oils, and bullshit products... Because theres no standards or professionalism in this industry... so these fools got smart and took lead with marketing and fake promises.

So many nutrient companies are posers. IF they really had ur best interest in mind, they would stop selling fucking water.

Same goes for Bennies. You need to make COMPOST TEA.

AACT Air Activated Compost Tea.

If you don't specifically use compost in your tea, its vermitea.

Anyways, if you need help with compost tea thats a whole new world, but thats the way to go about having benneficial populations in your medium.

go to the organic subforum and look up the sticky threads, amazing knowledge and its old, but still holds down.



now if you are a lazy asss smuck and really won't do the work and invest into compost tea, because lets face it, that shit is the best there is period, you have another choice.

EM-1 Known as Effective Microorganisms is a product eye highly recommend and make all my clients use.

ITs so fucking good, they make an edible version you drink.

ITS so fucking good you can spray where your stupid cat or dog pissed and the microbes will literally eat the odor causing shit away.

I don't recommend OGTEA anymore, and if you want the BEST COMPOST TEA.

Dr Earth products. Look no further. SuperActive™ Soil & Seed Inoculant This product tested higher than anythign else from oregon, infact the product exceeded by a ridiculous amount the claimed spore count.

All my dr earth experiences have been nothing but excellent.

i can't find the report but heres an article from it
ODA finds big problems with little organisms

https://www.icmag.com/ic/showthread.php?t=328247

That is the thread in the Organic subforum, the link to the pdf is in the OP.

Note the lack of any other informaton. Abstract, methodology, conclusion. It isn't much more than a report written with Word or the like.

You have drawn your own conclusion and state it as fact. That is interesting.

Storage and handling are likely causes of degradation prior to consumer use. There is a note that products were purchased within their expiry date, but I have pulled two or more "Best Before" stickers from microbial inoculants before. It seems odd that the microbes decided they were still viable and relabeled themselves.

Not just helpful in the soil, it would seem.

But regardless, most of these products are a joke, no disagreement there. The bad storage/handling is the cherry.

excuse me mister hardcore mode, eye had no idea you became an expert all of a sudden.

I'm not selling shit. I'm providing a professional horticulture solution used by professional commercial master gardeners for decades. Perilite causes cancer, why pour that shit everywhere, making a mess, and adding nothing to ur grow medium? You could fill the container up with soil or coco or w/e and use nematodes and save all your existing roots while providing more room for them...

The cannabis industry is full of flukes. No standardization or collective protocol... There are many ways to skin a cat, but why do it more than once?

your input is valid, but you have to remember, some folks have more than 500 plants and most of us grow medicine, which means we uphold the highest standards, but unfortunately not everything is controllable and there times when resolutions are required, and sometimes there are many solutions to one problem.

For instance the steam, thats new, but fuck that for anyone growing more than 4 lights. just the amount of time it would take to steam veg alone is unappealing.

Thank you Jah for a fungus gnat free garden

 

[Mikell]

Steam could easily be scaled, buy I would question the logic of anyone that did.

Nematodes work quite well (I've used them and read much), but are a hassle/eyebrow raiser to buy out of season.

 

[CannaBruh]

The microbe-lift comes double packaged with an MSDS that reads a bit scary.

How are you guys handling this stuff, seems a bit overkill for "nematodes".

I've seen avid package with less concern, not that it suggests it's any safer, but what are your guys' thoughts on the safety concern with microbe-lift.

FWIW, i used it once and didn't follow up, still have gnats.

 

[Mikell]

So, based upon your incorrect usage of the product, it didn't work that well..

Microbe-Lift BMC is only Bti as I recall, if you have information to present to the contrary or of a safety concern, post it.

Otherwise you are just spreading FUD (fear, uncertainty, doubt), when your opinion is already in question for stating abamectin appears (to you) to be a safer product.

Cheers

A.) been a master for a while now.
B.) when you call tried and true <free> methods "dumb shit" and proceed to offer paid alternatives you sound like a schill.
C.) i clearly said if you have more than a handful of plants that he (the royal you) should try out something more costly like nieman toads or whatever bottles of whatever they sell at the grow shop.
