Development of a method for detection of latent European fruit tree canker (Neonectria ditissima) infections in apple and pear nurseries

, 2017
Fruit tree canker caused by Neonectria ditissima is a serious problem in apple-producing regions with moderate temperatures and high rainfall throughout the year; especially in northwestern Europe, Chile, and New Zealand.

Effect of freezing of <i>Neonectria ditissima</i> inoculum on its pathogenicity

New Zealand Plant Protection, 2015
The fungus Neonectria ditissima causes European canker of apple To determine the pathogenicity of different isolates conidial inoculum of each isolate needs to be prepared Freezing inoculum ensures that conidia do not germinate before inoculation and facilitates screening of large numbers of isolates In this study conidial suspensions of three ...

The effect of wood age on infection by <i>Neonectria ditissima</i> through artificial wounds on different apple cultivars

, 2017
The age of apple wood may affect its susceptibility to European canker (Neonectria ditissima). Therefore, a glasshouse experiment was conducted with potted trees of six apple cultivars (‘Braeburn’, ‘Scilate’, ‘Fuji’, ‘Golden Delicious’, ‘Jonathan’ and ...

Seasonal susceptibility of apple trees to <i>Neonectria ditissima</i> wound infections

, 2017
European canker, caused by Neonectria ditissima, is an important disease of apple in the temperate climate of southern Brazil. Monthly inoculations of this fungus were carried out on various wound types on cvs ‘Gala’ and ‘Fuji’ over two productive cycles

Resistance against fruit tree canker in apple : evaluation of disease symptoms, histopathological and RNA-seq analyses in different cultivars, genetic variation of Neonectria ditissima [Elektronisk resurs]

, 2015
Neonectria ditissima (formerly Neonectria galligena, anamorph Cylindrocarpon heteronema) is the causal agent of fruit tree canker, which is regarded as a serious economic problem in apple production.

Neonectria ditissima cankers initiated in the second year of the nursery phase and at time of planting of apple trees

European Journal of Plant Pathology
Abstract European canker developing in young apple orchards may have been initiated in the nursery. Artificial inoculation of Neonectria ditissima was carried out at time of heading back and manipulating of branch angles in the second year of nursery phase sized trees of 10 apple cultivars, either T-budded or grafted (with or without ...

The use of rifampicin mutants and ERIC-PCR to track plant colonisation and in planta efficacy of bacterial biocontrol agents against Neonectria ditissima

Aims: Endophytic colonisation of apple shoots by bacterial endophytes with in vitro antagonism against Neonectria ditissima was evaluated. Their biocontrol activity against N. ditissima was assessed. Methods and results: Spontaneous mutants resistant to
