Trevor Ferguson, 48, was racing in the Supertwins event on one of Farquhar's KMR Kawasakis when the fatal crash happened.
"His wife and girls are in pieces," Farquhar told the Newsletter.
"I don't ever want Karen and my two girls to ever have to go through something like that.
"This is a sport I love, but I can't risk putting my family through something like that anymore - I have to think of them."
I'm finished with racing. I've lost a lot of friends, but it's different when it comes to your own doorstep.
Farquhar, who has been to the crash site to lay flowers in memory of his uncle, added that he wasn't sure he could even run a team in the future.
"I keep thinking if I hadn't offered him the bike and he'd been on his own bike, then maybe it wouldn't have happened - but life is all ifs and buts," he said.
Meanwhile, Ballymoney's Michael Dunlop dedicated his win in Friday's Superbike race on the Mountain circuit to Trevor Ferguson.
Dunlop pushed his Suzuki to an average speed of 112.54mph over the four-lap race.
Antrim rider John Simpson worked his way up from ninth on his Triumph to win the main race of the week, the Senior Manx Grand Prix.
