If you are infested man its a losing battle save your money and time. If you catch it early you might have a chance.

actually i root drenched them with Azamax and turned temps down as well as let them REALLY dry out and i dont notice any root aphids upon quick inspection. they were definately RA's before, they are gross buggers, and im sure i still got em... i dont even see any fliers anymore\. Im still hittin em with imid tho, i found the dosage, 5ml per 10gallons for marathon 2.

azamax/azatrol wont kill em. Good luck.

Hopefully it's labeled for use with grapes, stone fruits, etcetera. If so, that's where I would begin sorting dosing. You should know that with this higher percentage of imid, your pre-harvest interval is greatly increased.
