Salisbury City 1-0 Dartford
Jamie White scored the only goal as Salisbury inflicted an 11th defeat in the last 12 games on 10-man Dartford.
Striker White fired past Darts goalkeeper Alan Julian with a low left-footed shot from 12 yards after good work down the left from Elliott Frear.
Frear wasted a good chance to double the lead when he shot over from the edge of the box.
The visitors were then reduced to 10 men after Danny Harris got his second yellow card 15 minutes from time.

Salisbury City manager Mikey Harris told BBC Wiltshire:
"It wasn't our greatest performance of the season by any stretch of the imagination.
"Dartford are in a relegation battle, it was a scrap and we came out on top. We managed to match their spirit.
"It's a results business. I'll take a clean sheet and a 1-0 win all day.
"We're evolving as a team, we've shown we can win games in different ways."
