The genus Calonectria includes many aggressive plant pathogens causing diseases on various agricultural crops as well as forestry and ornamental tree species. Some species have been accidentally introduced into new environments via international trade of putatively asymptomatic plant germplasm or contaminated soil, resulting in significant economic losses. This review provides an overview of the taxonomy, population biology, and pathology of Calonectria species, specifically emerging from contemporary studies that have relied on DNA-based technologies. The growing importance of genomics in future research is highlighted. A life cycle is proposed for Calonectria species, aimed at improving our ability to manage diseases caused by these pathogens.

The ascomycete family Nectriaceae includes soil-borne saprobes, plant pathogens and human pathogens, biodegraders, and biocontrol agents for industrial and commercial applications. is a native tree species that is widely planted in southern China for landscaping purposes. During a routine survey of diseases in southern China, disease spots were frequently observed on the leaves of trees planted close to .

Calonectria leaf blight caused by species is one of the most important diseases associated with plantations in Asia and South America. This study aimed to clarify the distribution patterns of species residing in different species complexes associated with diseased trees and soils during leaf blight outbreak season in plantations in southern China. In this study, 482 isolates obtained from diseased trees and soils under these trees in eight sampling sites in three provinces were identified by DNA sequence analyses of , , , and gene regions.
