The 24-year-old, who has been banned for biting before, was accused of sinking his teeth into the hand of Stevenage defender Ronnie Henry.
The pair clashed near the touchline when Henry tried to wrestle the ball out of Labadie's arms after play had been stopped. Henry immediately appeared to signal to the nearby assistant referee that he had been bitten.
The incident is still being investigated by Hertfordshire Police, but the FA have charged Labadie, who has until 6pm next Tuesday to respond.

An FA statement read: "The FA has charged Dagenham & Redbridge player Joss Labadie with violent conduct following an incident during their game on 21 March 2015.
"Labadie has until 6pm on 30 March to respond to the charge."
Labadie was fined £2,000 and banned for 10 games for biting Chesterfield's Ollie Banks while playing for Torquay in February 2014.
Boro manager Graham Westley said after the match on Saturday that Henry, 31, had suffered "a nasty injury" and had "nearly lost his finger".
