Who's battling root aphids?!

merit 75...merit 75...merit 75.

I have my own thread about how I got rid of them for good....my secret....merit 75.

Mosquito Dunks, anyone try Mosquito Dunks?

Guy at the LHS recommended them for my root aphids, 1 day later, hundreds of dead bugs appear on the floor of my tent. All the ones I see in my DWC grodan/hydroton setup are black and dead. A few were twitching on the floor in death spasms. The plants look fine. Its some sort of bacteria that attacks and kills the little bastards, but is harmless and non-toxic to everything else... from what I'm told. That was like 3 days ago, got my fingers crossed. Plant root and top growth seems to have increased dramatically last two days. I top watered them and hundreds of dead bugs washed out of the hydroton. I used 1/4 of one dunk and just let it float in my 10 gallon res. I bet you could soak one in water and use it on soil.

Has this worked for anyone else? I wanna know those bastards are dead, dead, dead for sure.

i tore everything down, took clones (put in quartine), started seeds, bleached everything. switched to hydro to keep an eye on the roots.

i have wasted way too much time dealing with bugs, thrips, gnats, root aphids.

i just want healthy roots this time around.

i too think there are bugs in products these days...sucks.

well, my little green bastards are back. I definatley killed about 75% of them. time for round two.

Yes i too am battling these little shitheads, just gave them a dose of chilli, onion and garlic and some liquid detergent, i hope it works.

Have any of you had any luck with this method? I will have to do it again in 4-6 days and i hope the little bastards die, angry face, sad face and any other annoyed face indeed.

I inherited these from someone who was nice enough to give them to me, they didn't know. If this doesn't work I will go to the hydro shop and ask whats good for getting rid of them. I would rather organic stuff if possible, not a fan of the chems. enough from me.

I have this same problem but I'm in a hydro bucket system with no reseviour. I called around the hydro shops for what to do. If you're in flowering stage you can really only go Azamax. I called GH (produces Azamax) and for me they stated 10 ml to 15 ml per gallon for 6 to 8 hours, dunk plants when taking them out of that mix to remove as many as you can, then put plants in a fresh bucket with regular nutes and repeat 5 to 7 days out till a few weeks before picking That should keep them knocked down anyway. I'll report back on how it goes. Dirt growers, get the hell out of dirt and go hydro!

Read my post above, my use may not be the same as yours.

Well the first day of 6 hours soak then rinse and then re-bucket seems to be a big success! I had them pretty bad this morning, but after soaking in Azamax for 6 hours then rinsing in a seperate bucket of plain water (dunked them all the way to the rockwool) then putting them in a fresh bucket of nutes you can't even tell they were ever there! This really knocked the investation out! I'm saving the bucket mix of Azamax to re-use in 7 days to save money and I figure it should still be good enough to re-use. Of course be very carefull with the stuff, don't get any on you or your clothing but it is fairly straight forward as long as you take precautions and figure out steps to keep things clean. This probably wouldn't work too well for those ebb and flow systems. I'm beginning to really like this bucket setup!

I think I may be dealing with root aphids below I have some pictures and description of whats going on with the plants:

o I posted earlier that I noticed that I had these little black flying BUGS! Anyways I lifted the pots open only to find what look like dirt along the sides above the water level, I stick my figure and scrap some off and I get these tiny green and black 6 legged looking tick like! I cleaned them all of but also noticed that some along with babies were hanging in the root system! I believe that they are going through the roots up into the hydroton and flying out....I also believe the source is when i took a clone that my dad made me put in the backyard soil and replanted it to the RDWC system...I pulled out the backyard plant from the system as it was already dying and also noticed some rotting towards the base of the stem...Could this be contributing to the problems my girls are going through? Also what kind of bugs are these?

if you put a lid on the pot or hydro cup would that stop em from reproducing or getting in? I think I have fungus gnats and root aphids, I've tried goGnats, azatrol, Ed Rosenthals own, Dont bug me, all of which didnt work, maybe a little in the beginning, but these fuckin things are tough. Doktor Doom is the only thing that kills em on contact, with no perceivable damage to the plant, at least in my experience. I mean would it really help to make the move to hydro, ask emerald,

i had a gnarly root infestation as well recently in my dwc grow .. i opened one of the buckets and the walls were just covered as well as the roots they had eaten a good portion of my root system to one of my girls and she was starting to wilt which initially was the reason why i uncovered that bucket .. but i picked up some gognats ... and it wiped out the infestation pretty rapidly i applied it to the reservoir and also hand fed it to the plants for a couple days as well as foiler feed them a little as well just gotta stay on em cause they are tough as hell ...but i wanted to murk those p.o.s lol but they are notorious in DWC grows and since most of the products on the market dont harm the plants i would recommend to always use something of the sort as prevention cause that is always the best tool ...

Be careful using the Ortho Max bug b gone. It uses Bifenthrin which has a half life of 7 days to 8 months

I've got them too!
And this is my first grow =/

One of the vet's on here told me to cut back on the watering and they SHOULD die off, but no luck so far, the fuckers are resilient to say the least. I was about to my make a thread but I'm subbing to yours now.

Someone out here has to have a solution!

Letting the soil dry will help slow them down, but wont kill them off. They thrive in warm wet conditions. So you can lower the temp and let the pots dry out, it should help some.

If growing in organics, you can use liquid pyrethrin and insecticidal soap. Youll probably need more than one application dependin on how bad they are.The pyrethrin should kill them and the soap will clean a waxy residue they leave behind. They also secrete a poison in their saliva that will kill roots and wont let them grow back, so using an enzyme (hygrozyme, cannazyme, etc..) will help the roots breakdown the old ones. Using Azamax, and Azatrol will help control them, but not kill them off.

If growing non organic you can use the same method as organicly, but its cheaper with chems. There is quite a few different chems you can use, from what I've read and used Spectracide and Imidicloprid (Bayer tree&shrub, merit 75) seem to work the best. Spectracide is a contact killer while the Imid is a systemic. You should also use the Insecticidal soap to clean the roots. Depending on how bad your infestation is, you'll prob need more than one application. Only use in veg, you can use the Azamax and Azatrol in flower.

Other option is cutting your loses, and start over. They carry plant viruses and could infect the plants. Get rid of everything and clean with bleach solution. New everything or clean with bleach. Im trying to kill them now and went the chemical route.

Just ran 3 gallons of water with sevin and another 2 gallons with some kind of orth rose bush insecticide, I think I got them out of my bag of soil now,
I seriously think when I bought this soil they were already in it.


I'll check my soil tomorrow and see if they're all gone.
Hopefully then I can transplant to some bug free soil.

What type of soil? be careful and research the chemicals you use. Sevin may work, but ive heard bad things about it

You are just going to transplant the bugs to the new soil...

try boiling some tobacco in water worked so far for me. if that doesnt work just go noahs arks top and clone all the plants and start over, it sucks but if you cant get rid of them atleast you kept all the strains you were working with.and you only get set back a couple of weeks. but try the tobacco first by boiling it in water to pull out the nicotine and kill the mosaic virus. you can water your plants all day with it. and no shock exept for the critters

Bump, Nicotine is fooking toxic. 53mg/Kg body weight can kill a human. Does some damage to aphids too.

Also, I don't do shit unless I see it messing with the plant. Are you showing signs in your leaves (like yellowing and drooping). Are your meristems not stretching or expanding anymore. Do the new leaves look normal with 5 points or more?

Don't change your watering cycle, if you let the cubes dry out too much the aphids will feed a lot more on the roots. Just keep watering the SAME AS USUAL.

Chances are the aphids cant actually access all your roots as the roots are pretty tied up in the rock woool.

You might want to consider inoculation with some Glomus intraradices it coats the roots, fills the crawlspaces and helps to fend off root parasites.

Any chance of a link to the thread

Add Neem Oil to your food or preferably when watering.

I used 1/2 oz of Organicide in a gal of water, dipped all my effect cubes in there for 10-15 seconds each twice in one day and they all went bye bye. Once they are in your media some liquid pyrithene poured over each plant should do the trick.
