SCREENING OF APPLE CULTIVARS FOR RESISTANCE TO EUROPEAN CANKER, NEONECTRIA DITISSIMA

Acta Horticulturae, 2013
European canker, caused by the fungus Neonectria ditissima, is a severe problem in apple production both in Sweden and in many other northern European countries. Even when applying fungicides and good horticultural practices, canker damage occurs almost yearly in nurseries and orchards. Some years, devastating outbreaks destroy numerous trees. To date,

Lachnellula willkommii (European larch canker).

Abstract The European larch canker pathogen, L. willkommii, is apparently native to Japan, but established in Europe, where it became well known due to its damage to plantations of exotic and native Larix species, beginning in the nineteenth century. It attacks and spreads among the various species of Larix once it has been introduced.

Approaches for evaluation of resistance to European canker (Neonectria ditissima) in apple

Acta Horticulturae, 2016
European canker is caused by the fungus Neonectria ditissima (Neonectria galligena, formerly Nectria galligena). The disease causes significant losses to apple production in Sweden and many other countries with a temperate wet climate. Application of fungicides and good horticultural practices do not prevent canker damage in nurseries and orchards ...

Diversity of Cryphonectria parasitica in callused chestnut blight cankers on European and American chestnut

Forest Pathology, 2019
AbstractInfection of American and European chestnuts with the chestnut blight fungus Cryphonectria parasitica results in the formation of cankers, lesions caused by the growth of mycelia within bark tissue of the host plant. Infection of the fungus with Cryphonectria hypovirus 1 (CHV‐1) results in conversion of the mycelial phenotype from virulent to ...
