Torquay United secured their first back-to-back home league wins of the season as Hereford suffered their first defeat in five games.
Left-back Kevin Nicholson's free-kick from an acute angle put the Gulls ahead following a foul on Billy Bodin.
Winger Bodin, on loan from Swindon, then made it 2-0 before the break with a simple tap-in after a flowing move.
Nathan Elder headed over for Hereford before Taiwo Atieno's shot was cleared off the line to deny the Gulls a third.
VIEWS FROM THE DRESSING ROOM
Torquay boss Martin Ling told BBC Radio Devon:
"The most pleasing part of the week is the two clean sheets if I'm honest.
"We've scored six goals in two games but we've looked solid at the back.
"Rene Howe is a force to be reckoned with and someone you can build off."
Hereford manager Jamie Pitman told BBC Hereford and Worcester:
"I think this was a game of two halves in all honesty but we didn't really show what we were performing like in the last three of four games in the first half.
"But the lads have had a very good go at it in the second half and we might have nicked something somewhere along the line.
"The referee has got to be very certain that ball was over the line (for the first goal), but I thought the second one was dubious as well and I think he has made a mistake there as there was a foul on the edge of the box."
