Black Foot of Grapevine : Sensitivity of Cylindrocarpon destructans to Fungicides

Abstract

Black foot disease of grapevine is caused by Cylindrocarpon spp., with C. destructans being the main
pathogen isolated from vine cuttings and young vineyards in Portugal. Few recommendations for black foot disease
control are presently available, and they are not easy to implement within commercial nurseries. In this study, 14
fungicides were evaluated for their effect on the mycelial growth and conidium germination of four field isolates of C.
destructans. Mycelial growth of the pathogen was inhibited by DMI fungicides, prochloraz (EC50 values
