Narrative: We were being vectored to the ILS Runway 36L in DFW. I was the Pilot Monitoring. The First Officer was Pilot Flying. On base I had sequenced the approach and talking to ATC. We were given an intercept vector to join the Localizer and cleared for the approach. We were assigned 160 knots until BOBIN Intersection. My First Officer turned the heading bug; armed the approach and started to slow. It was a short vector and there was a tailwind at this altitude. As the Localizer was almost centered; he realized that he was not in green needles. I noticed it about the same time and said he needed to turn to stay on the Localizer. His reaction was slow to turn back and I suggested to turn off the autopilot and fly it back. He turned off the autopilot and commenced to turn back to the left; towards the Localizer. He was a bit over aggressive and went through 45 degrees of bank. We heard the 'Bank angle; Bank angle.' I saw the speed was still decreasing down toward Vt. As we were passing through 30 degrees of bank I said 'WHOA!' And after the bank angle annunciator; I said 'I have the controls.' I took the controls and advanced the thrust levers. As I did this I called for a go-around and takeoff/go-around thrust; flaps 8. I believe we were only at flaps 20 at that point. I guess I was not quick enough because we got the stick shaker. I believe it was a pilot induced accelerated stall; 45 degrees of bank and decreasing airspeed. We got vectors and an assigned altitude. (I blew through the initial altitude on the go-around/stick shaker recovery). I got the plane back to altitude and heading. I flew the go-around; approach and landing. We received vectors back for another approach without further issues.We were pretty busy at the time we were given the final vectors for the approach. I did not realize that he was not in green needles soon enough. With the speed reduction and the distraction of flying through the Localizer; we got too slow and the over banking put us in an accelerated stall situation. I should have been more vigilant in making sure that the approach was ready to be flown (First Officer in green needles). All else was ready and the tailwind and slower than normal speed were factors but not excuses.




Synopsis: CRJ-900 Captain reported taking control of aircraft after an unstable approach and loss of control by the First Officer.
