Amid much fanfare the former India captain was last year appointed as coach of the Jammu and Kashmir senior state team.
"Since he came the situation has worsened. He has created rifts in the team, he has done a lot of harm to the team," Beigh said.
According to a report, 12 Kashmiri players boycotted the round-four Ranji Trophy fixture against Andhra Pradesh alleging biased selection.
Beigh accused Bedi of preferring players from Jammu region over Kashmir.
"Let me tell you frankly with a heavy heart that I respect his stature, but he wants only Jammu players in the side," he told 'Times Now'.
"In the last match nobody has scored even 10 runs except one guy. There is a guy who has scored 10 successive ducks but I guarantee you he will be there in the side for the next game," he said.
The Jammu and Kashmir Cricket Association was learnt to have been in talks with the disgruntled players since they had boycotted their round-four Ranji match.
