Inhaltsangabe

Excerpt from Hypoxylon Canker of Poplar<br/><br/>In 1925 Schreiner (24) published the results of a preliminary survey of Hypoxylon canker in Maine, and found that in older trees the cankers were, for the most part, located in the upper part of the trunks. In one locality the percentage of infection in trees growing in the open was somewhat higher than in a forest stand. Faull (10) in 1930 reported the disease in Nova Scotia, and stated that stands are known in which the mortality has amounted to 70 per cent.
