I looked at the other Root Aphid thread and they were not to my liking. I don't have Root Aphids, but am bringing in cuts for the first time in years…. so I don't want these bastards.
Lets keep it simple. This is what I have found on the web -
(1) Acephate
The only thing that will kill a live root aphid is the powerful and carcinogenic Acephate (also approved for food and tobacco). Use it as a root dunk ideally. If you can’t dunk the pots then the next best thing is a good root drench (til runoff comes out the bottom of the pot)
(2) Imidacloprid
There are many different types of root aphids. Some may respond to Imidacloprid, but in the tests that we did with 9ml/gallon of 22% Imidacloprid, the root aphids lived 24 and 48 hours after treatment. Acephate killed them on contact. Research from the University of California Davis says that Imidacloprid will not kill live colonies of root aphids, but does seem to keep them from coming back once they are nuked with the acephate.
(3) Botaniguard
If you still are finding root aphids late into flowering (after all the acephate and imidacloprid), then the only thing you can ethically do is use a biological product called Botaniguard. You can get it in a powder Botaniguard WP or in a liquid Botaniguard ES. It is a really cool product that controls root aphids by giving them a fungal infection that kills them. It is not harmful to beneficials and is safe to use up to the day of harvest.
