I have not heard of anything here in NZ (where we don't call it cropdusting anyway), but who knows.

It depends on what "developed" means, but the next sentence seems to say they are currently earning $600 ph from it. I suppose it could be parsed to mean that a hypothetical "business" earns that.
PS: we do call it cropdusting
