    Read Your Label.

    I think that it has to have some rain to activate the chemical.
    1.5 inches maybe too much. All depends on how fast it came down......

    BUT Read the label it should have some info about this.
  3. Agree with mark. Was it foliar applied or granular? Down pour, or steady rain? If foliar applied, was it dry before rain? Granular application needs moisture to create barrier!
    Again, not enough info, and carefully read and follow label instructions!!!!
    I think your question has been answered!
