Mycovirus associated hypovirulence, a potential method for biological control of species.

is a large genus of filamentous fungi belongs to the division Ascomycota and was first described as . Innumerable members of this genus act as pathogens, endophytes and saprophytes and can be recovered from plants and soils worldwide. Many of these members are known to be phytopathogens. It is among the most diverse and widely dispersed phyto-pathogenic fungi which cause economically important blights, rots, wilts and cankers of many ornamental, field, horticultural and forest crops both in agricultural commodities and natural ecosystems. Some species, e.g. and have a narrow host range and mainly infect the cereals, whereas has effects on both monocotyledonous and dicotyledonous plants. Attempts have been made to control the diseases caused by sp. and to minimize crop yield losses. Till date, effective and eco-friendly methods have not been devised for the control of this devastating pathogen. A new potential of using mycovirus associated hypovirulence as biocontrol method against species has been proposed. The present review taking into account of worldwide researches to provide possible insights for -mycovirus coevolution.
