Help identifying root pest

Can you try to get a picture or video of the worm/larvae you were seeing? That could be helpful too.

Hypoaspis miles, predatory mites. I got some with a clone recently as well, theyā€™re usually mixed in with worms. They eat fungus gnat eggs and are harmless from my understanding

Get them stuck on a piece of tape or sticky trap so you can get a nice zoomed in picture

Positive identification of it is definitely first step.

These are really nice to have handy too

What kind of soil?

Fast or slow moving?

If its fast, itā€™s a hyposasis miles. A good bug. Eats bad bug larvae and eggs

Tell that to the dead plant

Unfortunately a high magnification still picture is the only way we are going to be able to 100% identify the critter

Soil drench with imiclapradid. 3x in a row
.
This will 100% kill any bug (minus sm, bm, rm).

Promis was the name of the product. Now discontinued.

Those are def not thrips. Thrips are long and skinny. I had them once and bought some killer pirate bugs from Arbico Organics and they devoured them suckers. I will never grow in dirt again. I swear that how I got them.

I still never got a replyā€¦
Fast or slow bug?
What type of soil?
And 1 more indoor or outdoor?

The vid shows slow moving. Atleast I consider it slow moving. Def not fast moving like the PM I have seen move. He is in a greenhouse.

Iā€™m gonna take a wild guess it is a beneficial bug and thatā€™s not what killed your plant but what killed your plant attracted those good bugs.

I can see HM scurrying around my pot lids before my usual soil drench with promis. This is ONLY used after potting any new soil.

I also have awesome eyesight. I did sign-off paint inspections and corrections on very expensive car paint jobs.

Fast or slow bug?
Video they seem pretty fast

What type of soil?
ā€œBulk organic soilā€ doesnā€™t specify if theres a brand

And 1 more indoor or outdoor?
ā€œgreenhouse plantsā€

Id like to add that maybe root rot could be the issue

Root rot would have a bad odor from the root area.

Iā€™m using a huge computer monitor and Iā€™m gonna guess most are using smartphones so you cannot see as well. I am almost positive it is the same bug that @pdxcanna posted a pic of. Also it has 2 ant or feelers and most of the other bugs I looked at do not.

This does look like the beneficial one for sure

Aphids heads do not look like that

Looks like you figured out this mystery 10hrs ago LOL.

Lol but we still have to solve the mystery of the dead plant

In his 1st post he mentioned worm/larvae. Maybe thatā€™s what attracted the Hypoaspis and thatā€™s what killed the plant. Or is that how the Hypoaspis starts out(larvae)?
I would assume the Hypoaspis starts out as eggs.

Hey guys so sorry for the delay, I was up late working.
So a few answers for youā€¦ as far as fast or slow moving, the videos would be the best demonstration of that. I would say they move pretty fast, and never seem to stop

Soil is called Gaiaā€™s gift from good earth organics.
I grow in outdoor greenhouses meaning they are covered for weather and sun dispersion but they are not sealed environments at allā€¦ basically outdoors with a roof. I have 2 greenhouses with plants and every single one looks healthy except the one that completely died in 4 days. Im about to go and really get into this issue and get better pics and video as well as scout all my plants. Like I said I donā€™t want to do any drench or flush or anything at all until I know what it is. If these are beneficial mites then I have absolutely no problems in my garden. As for the larva or what I saw, it didnā€™t look like typical larva to me although Iā€™m no expert. I just noticed a small very skinny white ā€œtailā€ just squiggling back and forth but couldnā€™t find it again. I usually associate larva with being fatter and having distinct appearance. This all happened as the sun was going down so right now Iā€™m going to really investigate and get all the details. I still donā€™t think itā€™s environmental as far as soil or watering anything because for that to have such a dramatic health issue while none of the others do wouldnt make sense to me. Iā€™m going to do the sticky tape trick so I can get some good pictures

Iā€™d definitely start with a ppm and slurry test of soil. Youā€™d be surprised at some companies that donā€™t adjust soil ph. Iā€™ve had some come in at 5!
