SCREENING OF APPLE CULTIVARS FOR RESISTANCE TO EUROPEAN CANKER, NEONECTRIA DITISSIMA
Acta Horticulturae, 2013European 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).
2021Abstract 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.

The European Larch Canker and its Relation to Certain Other Cankers of Conifers in the United States
Journal of Forestry, 1936Abstract The destructive European larch canker was first discovered in the United States in 1927, on European larch imported in 1904 and 1907 from Great Britain and planted in Massachusetts. In Europe this disease has been reported to attack Douglas fir and different species of pine, as well as species of larch.

Approaches for evaluation of resistance to European canker (Neonectria ditissima) in apple
Acta Horticulturae, 2016European 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 ...

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 ...

Understanding the genetic basis of resistance to European canker in apple
European canker, caused by the fungal pathogen Neonectria ditissima, is a devastating disease in commercial apple production. N. ditissima is principally a wood pathogen, which causes trunk cankers and dieback in apple orchards. Due to a lack of efficient cultural and chemical methods to control European canker, host resistance remains one of theopenaire +1 more source
