Neonectria can be conqered

Climate change resulting in milder winters and increased precipitation, leads to increased outbreaks of canker diseases caused by Neonectria spp. in the Nordic countries. SNS have decided to finance a network which aims to enable proper management of the infection and reduce the loss of income in forestry and horticulture.

 

Neonectria, a genus of fungi which currently causes significant economic losses in the Nordic countries, especially in apple orchards as well as in Christmas tree and timber production and even in urban landscaping with city trees. The genus is of importance both in horticulture and forestry and the problem is thus cross-sectorial.

 

Gather the knowledge

The researchers from Norway, Sweden and Finland in the SNS network Neonectria Cankers on Trees see a significant need to increase the knowledge about the distribution, biology and genetics of these diseases, and to reinforce collaboration between research communities and stakeholders across sectors. Experiences gathered by growers, people in extension services, silviculturists, nursery managers, arborists and other actors will be discussed together with research results for exchange and mutual benefit.

 

Nordic and global problem

Neonectria is a known problem worldwide and the network will invite speakers from outside Nordic region to benefit from their knowledge and establish new collaborations.

The network will focus on increasing the synergies between forest and horticulture. The three species of neonectria the network will concentrate on, N. ditissimaN. neomacrospora and N. fuckeliana, are closely related and therefore the management strategies developed  for one of the pathogens may be applicable for the other two.

 

Activities

The SNS network Neonectria Cankers on Trees will arrange a meeting in the autumn 2017 at Ås in Norway and an international symposium in the autumn 2018. In between the gatherings the participants will work in groups and meet on the internet. An online book of abstracts will be published as well as trade journal papers in the respective participating countries.
