The $^{19}$F($\alpha$,p)$^{22}$Ne reaction is considered to be one of themain sources of fluorine depletion in AGB and Wolf-Rayet stars. The reactionrate still retains large uncertainties due to the lack of experimental studiesavailable. In this work the yields for both exit channels to the ground stateand first excited state of $^{22}$Ne have been measured and several previouslyunobserved resonances have been found in the energy range E$_{lab}$=792-1993keV. The level parameters have been determined through a detailed R-matrixanalysis of the reaction data and a new reaction rate is provided on the basisof the available experimental information.
