Ryan Tunnicliffe was busy in the opening stages and dragged a shot wide from 20 yards in the fourth minute.
Following Tunnicliffe's poor strike, the game entered a lull with neither side able to create any clear openings for a while.
Ben Marshall attempted to spark proceedings into life with a driving run, but after beating two players his strike hit a defender and looped behind for corner.
Forest began to forge chances of their own in the latter stages of the half, with Britt Assombalonga seeing his shot blocked.
However, in the 37th minute Fryatt turned the ball home after Assombalonga's long-range effort had cannoned back off the post.
