Fungus gnats or WINGED ROOT APHIDS???

All these other methods seem like wayyyy tooo much time being wasted...

1ml per gallon.... 1 spray... say Thank you KONTOS
 
What kinda spraying ? Medium or foliage? I read it can travel up and down the plant... Been spending a fortune watering 55 gal at a time so this would be relieving.

Harsh smoke with spectracide granules? Makes sense I'll just go with the liquid form .
 
hey all i went through a very bad infestation with these buggers on my last grow. maybe this has already been touched on but too many posts for me to read all of them so i hope this is helpfull.

I run a very small closet system (dwc) using general hydroponics organic nutes. i use a 60w florescent t12 grow spectrum bulb and a 400w hps grow bulb. after researching my issues with my plants i finally figured out it was root aphids. i was able to kill them off in my grow area but if you have them in your house they will come back....here is what i tried in order of least effective to most.

mosquito dunks crumbled up on top of my medium....helped but did not solve problem

hot shots airborn style pesticide...really helped kill the flying ones but not the larvae.

dipping the roots of my plants in a h202 solution of 35% diluted at 2 tbs per gallon of water for a period of no longer than 2 minutes...i found this very effective at killing all of the larvea and non flying aphids...but you must also kill all the flying ones at the same time. if you do all three of these things at the same time you just may be able to beat these suckers...

off course the best way to beat them ....not to get them...maintain a sterile envioronment and allow as little as possible in from the outside of your grow area...:)

Just read the MSDS.
This stuff is not for beginners.

There's no specific antidote.
It's quite flammable.
The flash point is only 212F.
(Lamps run way hotter than that.)
And when it burns it produces Hydrogen cyanide!

Too scary for my sloppy ass.:hide:
Made me go buy more dryer sheets for prevention.
I'll head them off at the past.

Aloha,
Weeezard
 
Hydrogen cyanide ? Wow maybe I'll save the kontos for moms and use trazicide, imid, neem seed meal, orthene, pyganic,essentria, foliar/ botanigaurd , and conserve.

triazicide and hot shots

triazicide and hot shots

triazicide at 45ml/gal, 2 doses @ 5 day intervals decimated everything in the roots and did not seem to harm the myco or the fungas gnat larvae..have since added crumbled skeeter dunks at 1/4tsp/plant for the ones in 6" pots, a little more for those in #5's. Hot shots took out all the fliers. Azamax was used as a root treatment and a spray but was not effective, as other reports have suggested (not effectively absorbed by "sucking" type insects).

Seems to have worked, plants are recovered and exhibit good angles and sheen. Expected half life of triazicide at this dosage is 30-45 days, all treated plants were in veg.

Plants looked better immediately after triazicide doses. Contains G-C at .08% I believe.

Has anybody tried drowning these suckers? I've heard it works with mites in as little as 2 minutes..

i have heard that drowning them in hot water will kill them but if its too hot it will kill your roots as well.....not tried just heard...
 
MedicalMJ and Eclipse420, many thanks! I don't log in here but a couple times a week so sorry for the delay. Awsome input and advice...

I should have clarified, I have RAs. Verified with a 60x loupe.

Will be looking up the orthene regimen soon. I would toss my plants to better my odds but I have a few clones that I just have to save. A couple super high CBD low THC, and a Cindy99 original BG clone are at the top of the list.

I was going to get some Merit 75, but didn't realize it has 100's of days for a half life.

More research needs to be done... In the mean time I will bleach, bomb, and throw out my stakes and anything else that they could hide in. Maybe get a steam device as suggested... Thanks again

We seem to be backsliding a bit here. Many people with RA's also have Fungus Gnats.

Bacillus Thurengiensis israelianus [Gnatrol, Mosquito Dunks & bits, etc.] will kill FG's, but has no effect on RA's. Good luck. -granger

Well my luck with DE is starting to run out, it looks like after about 2-3 months it starts to break down to the point that it becomes useless. I have started to see the occasional flyer re appear after over a month of seeing nothing also the crab crawler guys are back. I have 20-30 days left before I am done flowering and everything still looks happy I think I will just barely squeeze out this grow in time and start over again which was my original goal.

don't worry about that month. maybe you will get 10% less yield, but that doesn't matter compared to the risk of a wrong treatment.
check my signature as a statement to that^^

good luck sir, keep us up to date :tiphat:

Cannascholar,
I don't think those predators will do much for you. They mainly feed above ground. they only go into the soil to pupate.

Neither nematodes nor any other predator will perform well if they are released into overwhelming numbers of pests. You need to knock the RA population back, then release the todes. Some chemical insecticides will kill them so take care.

A lot of the todes that are sold are not viable because they've been stored too long. I never buy them locally anymore for that reason. Also you need to release overwhelming numbers of them. Here are two good sources. They're fresh.

I called the guy at buglogical he also said they weren't effective however he recommended fetilae nematodes.

I'm gonna give the endeavor a try. $180 is a lot to pay but root aphids have been kickin my ass for 4 years or so now making growing way less fun and productve. Says it stops them from feeding in four days too they eventually starve to death. Also claims it won't harm beneficially or predators so I'm all in ill let y'all know how it goes.

About ready to try orthene on a few test plants due its phytotoxicity. Numerous research papers suggest it being more effective than imid and the other common ones. Little information is available about kontos as it is very new.

I'm beginning to think my best long term route would be to invest in a soil steamer to fry any critters and inoculate with bennies and nematodes. The sight of yellow leaves after spending a fortune on the best organic nitroen drives me crazy.

what do you guys think of using bayergarden bug killer to kill my Gnat problem 30 days into flowering, is it to late will it effect my bud?

been using Gnat off but it doesnt seem to stop the problem

i think fungus gnats are generally not that big of a problem and i think its seriously bad reason to put imidiicloprid on flowering plants with less than five weeks left to mature. that is a systemic and people use it for root aphids and if they give a shit they are well thought out enough in their regimen to get all these chems done in early veg. why are you so bent on killing fungus gnats in late bloom. just let em fly around and be. they dont cause harm in most situations. root aphids on the other hand need to be squashed. i would advise you to kill fungus gnats in veg and early flower with a less toxic approach. if you stay diligent youll get rid of em if you get on a program in about a round or two. root aphids on the other hand requires serious diligence. good luck!

That's a really bad idea.
I'm with str8 on this.
It's far too late for toxics.

If the gnats bother you, just lay dryer sheets to cover the soil surface.
Flyers only live a couple days and the sheets keep them from laying more eggs and infecting more plants.
Also prevents the hatch of new flyers.
Wont kill the larvae, but if you use the sheets from day one, you won't get FGs or RAs in the first place.
You best bet now is to ride this one out 'til harvest and defend your next grow from the getgo.

Just my 2 cents, TIOLI.

Aloha,
Weezard
