How long does the imid stay in the plant?

Do either of these bugs bite humans?

you're just spinning your wheels trying to use it on root aphids.

Your statement conflicts with bergerbuddy's earlier in this thread. I hate when that happens. FWIW, my hydro shop guy pointed me toward a BT solution (not Gnatrol...can't look now since lights are out...will update if I remember) for my aphid issue. Is Gnatrol (BTI) no good for aphids but other BT organisms can be used for aphids or are all BT variants useless against aphids? We need to hash this out more.

A big bottle of Bayer Fruit and Vegetable pesticide solution containing .25% Imid cost me $14 at Home Depot. Pretty cheap.

ETA: No, neither bug will bite humans.

BTi is specifically for the order diptera: flies and such.
this does not include any of the superfamily Aphidoidea that encompasses both regular aphids and phylloxera (root aphids).
As far as I know there is no BT variant effective for aphids.

Using Gnatrol had NO effect on my root aphid problem, at least using the max recommended dosing didn't kill them.... The reading I did on gnatrol backs up what Humble1 is saying, it is a very specific bacteria which is why it is safe for us to use.

I will say that the Zero Tolerance treatment killed the bugs, but as a root drench it also killed my plants. As I stated earlier, I tried it as a foliar (like it is designed) but it didn't work so I emailed the company who makes it. They instructed me to use 1/2 reccomended dose as a root drench and my plants died.

I will be trying Azatrol next time I get these things (and I think I have spotted some of these since the weather warmed up) as a root drench and may try imidiclaprod if Azatrol isn't effective.

ZT is BS and Ed should be ashamed of his own product.
smells nice. kills plants. fuck that noise.
you'll have better luck w/ pyrethrins IMO

Yeah I agree.... I was desperate last year as they were literally all over the place! I just hope someone else doesn't make the same mistake.

does nicotine based products work?? i wanna try an organic method to kill these fockerton's. i am so annnnoyed, now that i know what to look for, there must be 1000s of them per 4 inch pot. i was wondering why these vigorous pepper plants i have just won;t grow any further. now i know why, their roots are being raped & pillaged from behind.

[humble1]

nicotine based products will work, but they leave a nasty residue.
also, was the tobacco used in these products organic?
if not, the product itself is not organic.
i hate the overuse of that term.
regardless of what you decide to use, wear gloves!

I guess Ill shelve the BT solution I got (Safer Caterpillar Killer, contains BT kurstaki). It kinda gunked up my roots a bit too, which I don't like but plants don't seem to mind. Hopefully the IMID will do the trick and Ill keep researching this issue to see what else is effective. I hope we can keep this thread going (sticky?) since this critter is known in the grape world as "The Destroyer". Nothing to mess around with...

eta: Acetamiprid is also indicated as effective against phylloxera. Trying to source a commercial product but trade name is "Assail". Here's an interesting chart on pesticide effectiveness against certain bugs.
