Our experience with Assail protection has been 7 to 14 days with a surfactant and no rain. I always subtract 2 days of efficacy for every 1" of rain. I came across an article back in '05 that discussed the new insecticides' effectiveness and saved a copy to http://royaloakfarmorchard.com/pdf/New_insecticides.pdf. Doen't say much about how long protection lasts, but some good info none the less. Hope it might be helpful.

How many days does Assail protect against Apple Maggot? This early maturity/harvest and late AM emergence is making things interesting. We are at 4.5 flies per unbaited trap on 8/24. Imidan on 8/13 or Danitol on 8/29. Mix in SWD and an ongoing peach harvest and it's getting complicated.
