The invention relates to a wind turbine blade (5) comprising one or more turbulence generating strips (10), where the strips (10) are placed on a sur face of the blade (5). The blade (5) is characterized in that at least one j oint area (22) of the turbulence generating strips (10) and the surface of t he blade (5) are completely or partially covered by sealing means (23). The invention further relates to a pitch controlled wind turbine (1) comprising at least two pitch controlled wind turbine blades (5) and pitch controlling means for pitching the blades (5). The pitch controlled wind turbine (1) is characterized in that the blades (5) comprises one or more turbulence genera ting strips (10), wherein at least one joint area (22) of the turbulence gen erating strips (10) and a surface of the blades (5) are completely or partia lly covered by sealing means (23).
