I have no proof of the contrary, but I don't think ANY of the seed treatments that are claimed to be somewhat systemic will last into the pollination stage in either silks, flowers, or tassels. If that were true, we certainly would no longer have to spray for any of the later-season insects in corn/beans such as CRW beetles, Japanese beetles, SB aphids, Jap beetles in sb, etc. If there is proof of otherwise, I'd be interested in seeing it. It would have to be different proof than the fabled "Cornell report" issued a few yrs ago fcsting the demise of Monarchs due to CRW Bt.

I've sure never heard of these products lasting this far into the season. Again, post-applied insecticides are another subject.
