Spray thoroughly with a 50/50 mix of water and 70% isopropyl alcohol.

Repete the spray every 4 days until they're gone.

Make sure you get the under side of the leaves, stems and any hard to reach places they may hide.

And, you won't have to worry about getting thorough coverage because it is systemic.

Using anything systemic on a plant that you intend to eat is NOT advised!! Acephate is an organophosphate and is quite toxic!! And it is overkill for aphids. This is really, REALLY bad advice!!

FWIW, you don't even need to do the spray mix of water and rubbing alcohol - just put the plant in the kitchen sink and spray off all the critters with water from the faucet. If you are not squeamish, you can use your fingers to help remove and destroy.

Sorry, I didn't notice it was going to be eaten. You are advise to not eat a Acephate treated plant.

"FWIW, you don't even need to do the spray mix of water and rubbing alcohol - just put the plant in the kitchen sink and spray off all the critters with water from the faucet."

I agree. Just spray them off with a strong blast of water. Nothing else needed IMO.

Also agree with gardengal48 response.

Arunsky, I strongly suggest respectfully, that you refrain from making any further recommendations about pesticides.

Though this chemical is labeled for some edibles, the timing of such usage is critical. The label also expressly says that this exact pesticide is not for indoor residential use under any circumstances.

You clearly didn't read the original post or the chemical label, both of which you should do before making recommendations. You could have put an unsuspecting person and his or her family in a hazardous situation.

A very good rule to follow for every situation, is that we try the least toxic options first. Plain water has been successful in the control of aphids by most of those who frequent these forums and is certainly what we should be suggesting to newcomers.

Organophosphates are the basis of many insecticides, herbicides, and nerve agents.
The United States Environmental Protection Agency lists
organophosphates as very highly acutely toxic to bees, wildlife, and
humans.[1]
Recent studies suggest a possible link to adverse effects in the
neurobehavioral development of fetuses and children, even at very low
levels of exposure. Organophosphates are widely used as solvents, plasticizers, and EP additives.

My bad.

I'm glad everyone has a chance to learn that just because a package of stuff is sold in stores doesn't mean it's not very serious stuff, and often overkill for a given situation.
