    Alan,

    One important thing you did not mention is why you switched
    away from Imidan.

    If the reason is cost, for small backyard growers, this may not be
    a problem.

    If it is longer lasting (10 to 14 days) as opposed to Imidan (7-10 
days),
    that is an advantage.  Here in the Midwest, we generally have to
    continue spraying from after petal fall till shortly before harvest
    to control insects.  Does this Asana allow you to shorten this
    spray schedule?  One of the strong features of Imidan is the wide
    range of insects it controls.   Can the same be said for Asana?

    The advertising for Asana claims it resists sun and rain.  Is this 
because
    it has a built in sticker/spreader?

    I have a goodly supply of Imidan that I would like to use up, so if 
there
    are no major advantages to switching to Asana, I won't do it.  A quick
    search on the web did not show any suppliers for it.  Is it readily 
available
    in garden stores, or is it too new to show up there?
