After a relentless battle with these root aphids, I have decided to try and chemically eliminate them from some of my vegging plants. I realize that many things claim to kill root aphids, but the fact is many don’t work. After much research, I think I will use Promis (imidacloprid). Does anyone have experience using this hydroponically? I can find info about soil drenching, etc, but some of the plants that need to be treated are already set up in their DWC buckets. From reading, it seems that 3 back to back treatments of this should kill all of these bastard aphids and keep them from coming back.
I’m also beginning treatments for spider mite, etc (elimination and prevention) on my vegging plants again, cuz since I’ve stopped they popped up in my flowering room again. I’ve already started treating them with Azamax which has worked for me before. But I know it’s best to rotate treating with more than one product. What else should I be preventatively treating them with? Spinosad? Pyrethrum? Sns? Or will the Azamax work well enough in conjunction with the imidacloprid?
DE works in soil, I’m not going to bull shit anyone about the use of it in soil.Root aphids are relentless, trust me nothing really besides Imid will give you a complete kill. DE is useless on them especially in hydro.
You can try to beat this with chems, but I'm 99.9% sure one of those two pests will win in the end. They do not fuk around.
Ask yourself how much time you are willing to waste. Scrapping a grow is a really hard pill to swallow but sometimes it's the only correct treatment.
What stage of growth are they at?

He’s looking for help not a just throw em away answer. There’s ways to fight and save if he’s not to late. And DE does work I no from experience. Since I’ve started using DE I have not seen a root aphid since.

Ya, The habenaro spray drives everything out of the grow room even me. It’s like mace to humans, spider mites and eggs it kills on contact. I have to wear a respirator and goggles when I spray.Sorry I dont mean to come off as negative, just realistic. I've dealt with both of those pests quite a bit and they have given me more headaches than I care to remember. I honestly wish someone would have given me the hard truth when I needed to hear it.
As for DE, I've used it quite a bit.. If the soil is bone dry it works to an extent. But it did jack squat to rid me of root aphids or fungus gnats. It works great in dry environments for killing fleas in the house etc. I've just never had any luck with it against persistent pests in the garden.
Best spider mite prevention in my opinion is burning sulphur once a week if you have a space that allows it. They dont like to even enter the room if its sulphury. Make a very inhospitable environment for mites. A spinosad drench has been shown to help kill spider mites too.
I’ve been dealing with these root aphids for over two months, so I’m well aware of their behavior, how much they suck ass, blah blah blah. I have been controlling them naturally with Dalotia Coriaria (rove beetles) and frankly, they have been doing a tremendous job. But they have stopped short of totally eradicating them. I don’t think they are persisting in my vegging area well enough. This is the 3rd round of plants these aphids are on and I’ve had enough of trying to embrace nature. I will not be taking any new cuttings, etc to perpetuate things. I will finish the plants that are vegging now and then I will start from scratch. But I wanna kill what I can and protect these ones as best I can.
As far as the spider mite, I don’t really see them in the vegging area. I am going to give the Dalotia a bit more time to work and I will be treating the mite with Azamax in the meantime, so hopefully by the time I use the Promis there shouldn’t be any if there ever were. I’ve never heard of imidacloprid increasing spider mite. I did a search trying to find any info on this and was unable to find anything, so I’m not sure where the idea of imidacloprid created super all powerful spider mite comes from. But I think it’s a moot point in my case anyway.
you must not have looked too hard, there are several papers on it. In summary, Imid kills natural predators and increases egg laying rates in mites.

Interesting. I knew it would kill any beneficials. Hopefully I can clear any spider mite out with the Azamax and maybe I’ll try that habanero spray - how do you make that diesel?
I can’t really burn sulfur in my vegging area, it’s not closed off enough. I’d have my whole house reeking like rotten eggs. But that is something to think about in the future. I know burning sulfur kills PM as well.
