I never commented on products or anything...just your bad info but ok
Spinosad is for thrips. Aphids is a pretty general statement. Depends on what type they are (and if they are aphids). Some are easy to kill. Some aren't even worth the time trying to fight.
Short answer from me is whatever you choose to spray, approved or not, its a battle. There is nothing on the market (even using something like nasty ass merit 75) that is going to be a one and done solution. I have never seen a product that will wipe out aphids in 1 crop cycle. Once you get them you generally isolate moms and burn the rooms with heat, totally disinfect, and pretty much start over. Then you make the choice of trying to save your moms or cutting your losses. Best way to get rid of aphids is not to get them in the first place. I'm not an OD dude so I have no clue how they deal with them (minus natural predators) but indoors if you find out you have aphids you done fucked up letting it get to that point. Specially if it's RA's. I lost Pre98 years ago because of this and had to bite the bullet. Shit happens sometimes.
That's a real answer that most people wont listen to. They will listen to some dude at a hydro shop (which generally dont have a fucking clue on insecticides or IPM) or think buying some $100 solution in a bottle will solve all of their problems. If you look at other industries and how they deal with them, while not using nasty ass chems, it will give you a pretty good picture on it.
