Without context, I'm guessing low-drift nozzle (for spraying pesticides). I found a hit for "Anti-Abdriftduese", which I think is what is actually meant, as drift/Abdrift is a problem in spraying that you definitely want to prevent. For some reason I'm having trouble inserting the links for the references, so I'll do it here:
