The Vanarama National League South side have slumped to 16th place and have only won once since November.
Tuesday’s defeat at Maidstone United left the Kent club seven points off the play-offs and despite Dowson’s insistence that the club would finish in a promotion position, the board have acted.
The Princes Park club have dropped 21 points from winning positions this season and in a lengthy statement, officials explained why the time is right for change. Club legend Tony Burman takes over until the club appoint the former Hampton and Woking manager’s successor.
“Our current league is competitive and unforgiving. Sometimes results simply don’t reflect the amount of effort and goodwill that individuals put in to secure success. However, one thing we all know about sport is that results matter and part of being custodians of a club like Dartford is the need to always reflect on what’s best for the future.
“Dowse’s arrival at Princes Park was widely welcomed by the DFC family and we all looked forward to a period of success on-and-off the field. No one can question the enthusiasm and commitment of Dowse and his wider management team.
“They are passionate football people through-and-through and on a personal level it has been a pleasure to work with every single one of them.
“However, we have to accept that the results have not been forthcoming and the Board has a responsibility to make decisions to focus on progression. The Board has taken the difficult decision to relieve Dowse of his managerial responsibilities.
“Tony Burman will take temporary control until a new manager is appointed. It should go without saying that we thank Dowse and his team for their efforts and wish them all well in whatever they pursue next in football. They will always be welcome guests at Princes Park.”
