I have read through a bunch of Root Aphid threads and have a quick question. Do I need to apply repeated drenches of Bayer Complete to get rid of Root Aphids or just one? I have already applied one drench about a week ago and wondering if I should drench another time or two or is once going to be sufficient?
How long does it take until met52 seriously affects the root aphids?
Few days, 2 weeks?
When Imid (Met52) works, it's an instant kill, which is where most people make a fatal mistake and think thats the end of it. If you miss one egg or one flyer they comeback in full force although it may take weeks before you notice at which point you back to square one. Whatever you do plan for multiple applications no more than 6-7 days apart. It all depends on if the species of RA's you have is resistant to Imid. The beauty of Met is that is like 20 times more concentrated than its Bayer counterpart

As far is I know Bayer doesn't have a "counterpart" of Met52. Imid and Confidor both contain the active agent "Imidacloprid".
Met52 contains a fungus called "metarhizium anisopliae".
Just wanted to clarify that nobody gets confused....

Soil is cheap. Toss it and start fresh. Why take the unnecessary risk of starting a new crop with potentially infested soil?
If the RAs developed a resistance to imidacloprid....then a thousand drenches/dunks will not get rid of em, cuz the survivors of each subsequent imidacloprid treatment (yeah lots will die from the treatment--but not all) will pass the imidacloprid resistance trait to their offspring. Google "imidacloprid insect resistance" to see people smarter than me have to say about imidacloprid resistance.
RAs are difficult to eradicate--I know, been there and done that...and yes it is possible (but not with imidacloprid).
