The Control of Black Rot Guignardia Bidwelli –A Dangerous Fungal Disease of Grapevine

This pathogen, which are producing the black rot of grapevine Guignardia bidwelii (Ellis) Viala and Ravaz, and its anamorph Phyllosticta ampelicida (Engelman) van der Aa, is an ascomycete fungus that is responsible for about 5 to 80% production losses in grapevine cultures, although it is less frequent than other fungal diseases from this crop. In the present work, we review the problems related to this pathogen, its life cycle, virulence factors and mode of action, and especially the prevention of the infection and ways to control it, its spread in the world and in our country, We discuss practical considerations for control methods of the black rot, agrotechnical methods, genetical methods, chemical (fungicides, natural products the use of plant resistance stimulators), and biological control.
