If the BT is still active, yes, it ought to be killed by Physan.

I treated all of my plants with BT last week to ward off the leaf
rollers that were attacking. I havent done a prevantative Physan
spraying in quite a while and I think its time to do one. If I spray
physan on all of my plants will that kill the BT that I applied last
week?
