Alex Ferguson's side had enough chances to notch up a bigger scoreline but substitute Gabriel Obertan missed a couple of sitters.
Michael Owen missed a great chance for Manchester United in stoppage time at the end of the game.
United made the breakthrough when Berbatov showed good skill when he got on the end of a cross from Evra.
He got the better of Ryan Nelsen, twisting and turning before sending a shot beyond Robinson for his fourth goal of the season.
United boss Ferguson decided to make a change after 64 minutes bringing on Obertan for the ineffective Nani.
Obertan made a delayed debut in the Carling Cup victory against Barnsley in midweek after recovering a back injury.
He almost made a dream start in the 67th minute following a defence splitting pass by Anderson.
