''Neonectria galligena'' is a fungal plant pathogen. It causes cankers that can kill branches of trees by choking them off. Apple and Beech trees are two susceptible species. ==Disease Management== ''N. galligena'' is a difficult pathogen to eradicate, however, there are many ways to manage the disease to limit its spread and infection rate. In order to effectively control ''N. galligena'' a combination of cultural and chemical treatments must be used. Cultural control Multiple cultural techniques can be performed in order to manage the spread of ''N. galligena''. In order to minimize the number of wounds, through which the pathogen can enter, select trees that are well adapted to the local climate. In certain areas, trees must be able to resist damage due to environmental stresses such as cold temperatures. If cankers are present, it is important to prune out the damaged tissue in dry conditions. Dry conditions are unfavorable to the pathogen because it prohibits the development of fruiting structures and spore dispersal. It is essential to disinfect the equipment before and after pruning to prevent the spread of the pathogen to uninfected trees.〔 Cankered prunings must be removed from the area and burned to eliminate the risk of continuing spore production. It is crucial to limit the use of high nitrogen, especially in manure, because it will encourage and facilitate the development of ''N. galligena''.〔 Chemical control 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Neonectria galligena」の詳細全文を読む スポンサード リンク
