Qualter’s exquisite effort from 35 yards handed the Pilgrims a 12th minute lead at Hurst Cross but United’s afternoon took a significant downturn four minutes from time when substitute Brad Abbott was red-carded for apparent foul and abusive language.
Ashton substitute Liam Tomsett capitalised less than two minutes later with the Robins’ equaliser to seal the Pilgrims’ first draw of the season.
