I never have 'wing drop' on final approach - not in the stalled sense of the word - on the other hand if it is a little lumpy I get the student to use coordinated aileron.....I NEVER advocate picking up a wing with rudder - anyway its pointless - because to pick it up with rudder you have to yaw the nose......and that means that you will no longer be straight on your runway heading....
I do an exercise on medium turns - rolling around a point - it gets the student counteracting adverse yaw with an appropriate amount of rudder - done properly this is how they should 'pick up' wings in turbulent conditions.
