After Saturday's 1-1 draw with Blackburn, Barton told Absolute Radio that the Morocco international needed to buck up his ideas.
The former Newcastle midfielder also admitted he has yet to see Taarabt's so-called "genius", all of which Warnock feels was a bit harsh.
"What he is saying about Adel I think is a little bit out of order," he told ESPN's Between the Lines.
"I think there is one or two lads in the team at the moment that could do better so sometimes you look elsewhere.
"If he wants Adel to chase about and tackle and run, he is never going to be able to do that."
Asked if it was Barton's place to make such comments, Warnock retorted: "I've not spoken to him. You're just telling me what has been said.
"I'll probably have a chat with him (on Tuesday) and see what he actually said."
