Should be as affective, as I expect all pyrethroids are similar.  Asana
claims to be more weather proof than others because some vegetable oil is
in the formula but a decent sticker should more than compensate for that.
Asana  certainly takes care of AM and CM and I'm confident from many
exchanges from other growers that Triazide does also.

No, I was talking about Triazide.  I'm sure Imidan lasts for years but you
can contact the manufacturer for specifics.

I believe it works fine on PC because Asana does and because on the Garden
Web fruit and orchards forum many participating fruit growers have been
using it for years with great success on sites where they lose everything
to PC without it.  I suspect any controversy is the result of its short
shelf life.

Pyrethroids work better against stink bugs and other bugs than Imidan and
have a long residual quality even after the poison isn't killing- they are
irritants for a period of time after losing toxicity.  They are also more
than adequately affective against PC in home orchard conditions.  At least
as good as Imidan against Leps as well.

Imidan has kick-back by way of penetrating the small tunnels and killing
larva and eggs in the fruit.  None of the new pesticides does a real good
job of this, although the neonicinoid Assail is said to have some
kick-back.
