+1. The biggest benefit of BD is the increased awareness it imparts to the farmer/viticulturist.

It's unfortunate that the really ardent supporters of BD seem make BD an even bigger target by promoting their views in a nearly evangelical way. That said, it's just as unfortunate that many scientists and/or pseudo-scientists seem to have a knee-jerk lock-and-load mentality in addressing the issue. Does the name Pavlov rig a bell?
