Agree with Allen on this one. Low levels or absence of AFB for one season
in your own area doesn't mean much.
As per resistance, I'm amazed that we got more than 40 years out of OTC
before we saw resistant AFB. That was a slow development, not quick at all.
As I understand, Wilson and others wanted EPA to approve OTC and Tylosin,
alternate years of use to try to avoid this situation. EPA only approved
the one, so we used it until the predicted resistance finally showed up.
