The primary effects of controls apply at all stages of controlled flight. 'Picking up a wing with rudder' is an archaic myth which is total rubbish. At the stall, rudder should only ever be used to maintain balanced flight (ball in the middle). NEVER should any attempt be made to use the further effect of rudder to attempt to return the aircraft to wings level flight, neither should any attempt be made to recover to wings level using aileron until the wing has unstalled.
The Standard Stall Recovery is ALWAYS 'FULL POWER and control column CENTRALLY forward until an attitude is reached which results in stall identification ceasing, at which point maintain that pitch attitude. THEN roll wings level using aileron whilst keeping the ball centred. THEN recover from the descent!!'
On an approach you are sufficiently far from the stall to use the flying controls in the conventional manner. So, if you suffer a wing drop due to a gust of wind, roll back to wings level using aileron, but KEEP THE BALL CENTRED!! Older aeroplanes had considerable adverse yaw with large aileron deflexion and it was VITAL to use the rudder to balance the aircraft as a result. This gave rise to the myth that these large rudder movements gave the primary corrective force needed to return to normal wings level flight.
LOW+SLOW+COARSE RUDDER=SPIN=DEATH!!
