Big Grow , Big Problems !!! FUNGUS Gnats , Eggs, and Larvae !!!

[schlafmütze]

hey guys i am in War with Fungus gnats, egs and Larvae.

I tried a lot of things.

right now i have a room wich is 12 Qm and with 3600 Watt. 144 Pots of 7Litre Coco.

the last run i dont thing that this animals will harm my plants a lot. but after harvesting only 1/3 from what i usualy get and not so good quality i know this animals making a lot of harm.

Before i start the next run i use ARDAP Fogger for 2 hours. For the Adults only.
then i used H2o2...3% mixing one part to 4 part. Maybe i dont take enough? i take 240 Liter for 144 pots. 90 liter drain from that. but they are back. than again ARDAP Fogger.

for a few days it was nothing to see. because the new cuts are waiting i put them in the pots.

I use nematodes two times 400 million (4 packet of 100million), i use bti tablets. and soil mites for the egs. but i am still fighting.

I have for this room 200 Yellow stiker on, in and arround the pots for the adults. but the larvea and egs are the big problem.

There are some products called "Neudomück pro" (liquid) , "Vectobac", "sollbac". wich maybe work better ...But i can not buy this in germany.

Some extra question:

1)Can i try h202 on the coco again when the plants are allreday in the pots???

( today is flowering day 10 / 10 growing days (normal i give 6 to 7 grow days but becaus of the fungus i give them 3 extra days and will stop the grow with grow stop)

2) do you think hot water is a good solution? for Larvea and eggs? and if yes how much degree it would be perfekt to kill all of them. and from wich degree the plant and the roots get propblem?

3)i read about Microbe Lift!! is this a good prduct for the Larvea and eggs?

4) do you know where i can buy one of the products ( Neudomück pro Liquid, Vectobac or sollbac)

5) what is a perfect Ratio for Bleach? dcan i use Bleach during the plants are in the pots?

thx a trillion times.

Stop using chemicals.
These will solve your problem, gradually but it will get much better in some weeks.

Put them practically anywhere you see the flies, they live in the soil so mostly put a lot of strips like bridges for them to move on. Basically traps everywhere

Good luck

Hey Bro......Welcome to IC .......Sorry for your fungus gnat problem , seems like all you`ve tried has gained little to no help in getting rid of the lil bastards.......Here in the US the "Gnatrol WDG" which is BTI/water dispersal granules is the standard of the industry for total eradication of fungus gnats , but you stated you`ve already tried BTI , so just hang on and let`s see if I can help .......

First off.....Fungus gnat eggs and larvae are notorious for already living inside coco before you even use it , so the best cure before even planting in the medium is a drastic measure but it works.....If you`re using dried and compressed coco bricks or bales , re-hydrate them with "boiling water" , and guaranteed all eggs and larvae will die......even if you`re using the fluffed out and already hydrated bags of coco , and also......

If you`re re-using your coco , again.....before re-planting , boil the water and run it through long enough to kill any eggs and larvae that`re residual after the grow cycle ends........The yellow sticky traps that you`ve already put everywhere will take care of the adults , and the BTI used repeatledly every week to 10 days should by all intents and purposes kill all eggs and larvae existing in your medium after that .......anyways.....That`s all I can offer , so good luck and hope this helps......

Peace.....DHF...............

Get some Mosquito Bits. It BT spores you add to the water or soil. Works great.

Thx guys.

Koondense, i have a lot of the yellow strips in, on and arround the pots.

DunHav`nFun , i can not boil the water . Normaly it would be a great idea but not when you have 144 of 7 liter Pots. how i can boil so much water?

I can use hot water from my bathroom , but how much degree it needs to kill Larvea and eggs? these days are Cold in germany and i think i can produce 50 grad celsius of hot water. in summer maybe 65 of grad celsius. I can connect my auto watering system to the bathroom and give it a try.

What about the roots of the plants? How much degree they can get without any harm?

Three Berries here in Germany i can not buy it from amazon. Do you have another product for me wich contains B.T.I wich i can take?

i read that Vectobac or Gnatrol are good but i can not buy these in germany.

I don't know of any but BT insecticide products are pretty common. Look for pond maintenance products to stop mosquitos.

Hello,

Against insects you can spray some nettle manure ( if you find them ) .
One recipe to make it : Nettle manure, a simple recipe for garden free fertilizer

Liquid manure spraying:
After just one day, we get an extract from the water and put aside nettle, which can be used undiluted for spraying plants against pests and fungi.

I am guessing he means Nettle FPE.

 

[GoatCheese]

You can find ’bacillus thuringiensis’ products being sold in Germany/EU on Ebay.
Do another ebay search with ‘bacillus thuringiensis israelensis’

Hello,

yes, there is a topic on icmag -> https://www.icmag.com/forum/marijuan...042-nettle-tea

I already spray nettle against Sciaridae ( dark-winged fungus gnats ) and they desappear!

You can always spot an indoor grow by the spectrum of pests.

Among other things, there's no predator bugs, so the grow is like a BIG petri dish.

I recommend Ladybugs and Praying Mantis eggs (if you can get them), which also means you will have 1500 ladybugs in your grow room and nearby rooms.

If it happened to me right now, I would keep a bag of sand handy and pour it on any grow media that had bugs.

Immobilize the little suckers.

Diatomaceous earth works too when mixed in the top of the soil. Non toxic and organic.

If you have a bad Fungus Gnat problem then you are probably watering too often. Let the pot dry out more before watering. They can't live in dry conditions.

idk if you can get it in Germany but kontos by bayer is an extreme solution but will undoubtedly work

it is systemic so only use in veg, but mix 1ml per gallon with your feed and they'll be history
its the lesser evil as far as systemic answers
