Pyganic for knock down. Warm water at 105 F will kill what is in the pot. Water soluble neem that is 6%, sprayed at 3% works well too.

Warm water for the success. Rice aphids is the term where you will find lots of information.

Don't over water either.

You will find them around the outside of the pot feeding on the new roots... rarely will you find them in the middle of the pot.

If you are indoors, turn on the lights and run the room at 120 F. for a couple of days. Warning, plastic starts to deform hahahaha....

I have finally made it to the end of hi thread. What a ride. It took me about 3 weeks to do it. I read about 25-50 pages a sitting. I didn't do it every day though and I puffed a lot when I read.

First... What happened to eclipse? He hasn't posted since July of 2015.

There were a few people posting pictures that had two spotted mites that nobody mentioned. There are some resistant ones being passed around.
Kontos, sm-90, Regalia and Venerate. SM-90's best feature is the way it conditions your soil. If you have soil that doesn't drain well or absorb fluids well sm-90 will correct that after one or two applications. This helps whatever additives you are using soak into your medium. And it smells great. Regalia and Venerate are organic.

Well, I just found out some of my plants have the dreaded Root Aphids...and I havent brought in any clones or plants from anyone else's garden in a few years.
Prime suspect is a few non-canna plants we brought home from a local nursery a couple months ago, even though I inspected them carefully on site but had several of them die suddenly. Never doing that again.


Anyway, I've done 3 biological treatments since I've noticed them.

First was a rootball soak in full strength OG Biowar Foliar with Grandevo, since it was all i had on hand while I waited on some botanigard WP in the mail. This really didnt seem to slow them down at all.

Three Days Later I did 5-10 minute root ball soaks in full strength Botanigard WP. This reduced the number of crawlers I saw walking around on the rims of my pots.

Another 3 days later, I did a soil drench with nutrients and full strength botanigard WP and watered until heavy run off.



Its now been two days since my last treatment (and about 7 days since I began treating), but I'm still seeing some of these bastards on some of my plants, though they seem slower.

Does anyone know how long beauveria bassiana takes to infect a root aphid and kill it? I inspected a live RA under microscope last night and could not tell if it was infected by BB.

I'm not sure about these answers. It does take at least days to kill many of them. Treating more than weekly seems unnecessary to me, as long as your microbes are fresh and have been stored properly.

It's very important that, at least once, the entire root ball gets a good soak. Good luck. -granger

Treating severe infestations with BB every four days works for me!


Botanigard didnt really put a dent in my RA problem and I wouldnt even consider my situation a severe infestation. I'm using a brand new bag of the stuff too.



I did full strength applications every 3 days and at least once a week, completely submerging the rootballs for a minute in full strength solution. Drowning in water seemed to kill more of them than the Botanigard itself. I did this for several weeks



Finally, I ended up buying a small bottle of Azera (pyrethrin+azadirachtin, OMRI) and did another rootball soak for at least 1 minute each per plant. Havent seen a Root Aphid since and my plants/root health are starting to recover nicely. I'm going to continue doing weekly drenches with the botanigard for maintenance until the bag is used up.

The rootball should be submerged for at least 15 mins. so the part just under the base of stem gets completely soaked. This area is RA Central. Good luck. -granger
 
Not sure if I had root aphids or soil mites or something else in there. Little fudgers were hard to take pictures of or see with my phone microscope. They are not all over the place like some others. I have had to dig into the top of the coco a little to see them and so far maybe seen 10 at most. Nothing crawling up the sides of my black felt pots. My plants in flower are showing signs of mg def and I am pretty sure my nutes are not off. I am able to pull out some of the plants still in veg in little solo cups but I can not see anything on their roots and nothing on any of my leaves. Again, not sure whether these are RA

So on to my battle. I have started right off the bat last night with an Azamax/sm-90 drench at 6% Azamax and 5ml/gal of SM-90. Prior to doing this I top dressed my felt pots with gnat-nix grow stones. This will hopefully keep any of the buggers in the pots from getting out. It is made from recycled glass and I think works very similar to DE but doesn't affect ph.

This morning I set off a Pyrethrin fogger. I have also ordered SNS 209 and Evergreen 5% Pyrethrin. Next watering should be tomorrow, will be with nutes and sns 209, The following watering will be a root drench with Evergreen. The day after I plan on setting off another fogger and then repeat using the drench and the sns 209 with nutes for about two weeks and bombing every 5 days, and then just continue with using the sm-90 and sns 209 all the way through harvest.

I think going forward I will make gnat-nix stones a staple in my garden. Use it as a top dressing or even bottom dressing, to prevent these bugs from even getting into the root zone.
 
I wouldn’t go to all that effort until you have a positive diagnosis.

Very true. I already ordered the SNS 209 and Pyrethrin. Going to definitely use the sns, not 100% sure I want to do a full pyrethrin drench. Maybe use a lower dosage. Anyone know how this affects the plants in flower in coco??

Definitely will keep the sm-90(always been there) and now sns-209 in my regime as preventative.

Just a quick edit: I am pretty sure what I saw are soil mites. They were too fast to be root aphids, and were spotted on my top portion of my soil. Still glad I did this as a little preventative and kind of kicked my butt back into place to better maintenance habits

The results of my potato test... RA or mites? Cannot be seen by the naked eye.

I watched all three vids. Those are not root aphids unless they are larvae, but I don’t think you would have larvae without adults.

You need to give more background info, what made you do the test, is there plant damage, have you seen flyers in sticky traps? What medium are you growing in?

I’m in coco... been dealing with gnats off and on for years. A few plants look shitty, have a nematode problem.. posted a thread with vids of them too... have SF nematodes coming tomorrow to help clean up my buggy grow.. they look like mites to me but the my have hairs out he back that almost look like tailpipes. I used to release predator mites years ago but I doubt they’ve hung around.

Yes I think you’re good, a lot of mites have hairs like that!

Steinerama feltiae nematodes always work for fungus gnats ime!
