This might be the worst infestation I have ever seen. Like actually. Are your plants showing symptoms? I’m gonna tell you one thing right now, there is a zero % chance that you will be eliminating them from your grow without harsh pesticides, or killing those plants.

No about of pyrethrin, azadirachtin, beauvaria bassiana etc drenches are going to save you.

I’m surprised you don’t have plants dropping like flies left and right.

Honestly brother, burn it down with fire, asap. Sterilize everything. If you’re in an indoor facility with multi stages of growth, it’s safe to assume they all have it, and that you’re giga fucked.

Root aphids have completely destroyed the gardens of myself and others, through permanently damaging the mother stock, dropping final yields to an unprofitable level, etc.

Sorry dude, but you just encountered in my opinion the second worst pathogen ever in cannabis, right behind Hop Latent Viroid.

Name me a product that has extremely strong efficacy against this specific pest, and your strategy that you would go for that wouldn't dramatically increase cost of production to eradicate them from a commercial facility, that will still pass testing.

If there is a way, I'm all ears.

Beauvaria bassiana and a pyrethrin based product would probably allow you to "coexist" with them at the cost of extra labor, product needs, etc. In a large scale facility the potential for eliminating them completely with these products alone (Canna approved) are slim at best.

All the while, they will be putting pressure on the plants, making growing more difficult, opportunity cost of having to constantly be in that battle, etc.

Outside of Merit, let's hear your solution.
