LSU (23-2, 11-1 SEC) moved on game closer to clinching a second straight to a Southeastern Conference regular season title, holding onto a one-game lead over Tennessee with two games left.
Arkansas (13-12, 5-7 SEC) jumped out to an early 7-2 lead, but LSU proceeded to rattle off a 17-0 run to take a commanding 19-7 lead with 5:56 left in the first half.
The Lady Tigers led 27-14 at the break and opened the second half on an 11-2 run to lead, 38-16 with 16:43 left to play. The Lady Razorbacks never got any closer than 18 points the rest of the game.
"I'm going to start with the positive," LSU head coach Pokey Chatman said. "It's a win. That is the short list."
LSU's defense held Arkansas to 26.9 shooting percentage and no Lady Razorbacks reached double figures in scoring. Three players had six points to lead Arkansas, while Kristin Moore had five points and nine rebounds.
"We need to correct our ability to take care of the basketball," Chatman added. "We shot 55 percent, but did not give ourselves enough opportunities. That is something we are going to work on."
LSU shot 54.5 percent from the floor and grabbed 45 rebounds, but committed a season-high 23 turnovers. Arkansas had 31 rebounds and 15 steals.
Augustus, a senior from Baton Rouge, moved into third-place on LSU's career scoring list with her game-high 26 points and slide into 10th-place on the Southeastern Conference list.
Sylvia Fowles added eight points and nine rebounds, while Florence Williams eight points and five boards off the bench.
The Lady Tigers will travel to Tuscaloosa on Thursday to play Alabama at 7 p.m. CST at Coleman Coliseum. LSU will enter the game with a chance to claim the SEC regular season title.
