You should always pick up a dropped wing with rudder.
Or use rudder to prevent further yaw, as I am sure you know, using the rudder to yaw the aircraft in an 'attempt to pick up the wing' is just accelerating the down going wing, which may delay the onset of the stall slightly and result in a more equal stalling of both wings at the same time. Or if large rudder inputs are used may cause a spin entry in the other direction.
