II. Root Rot of Coniferous Seedlings. 



The study of the diseases incidental to coniferous seedlings, 

 while of great interest to the plant pathologist, may be of the 

 greatest practical value to the nurseryman and forester, 

 especially when not only the cause is ascertained, but when an 

 appropriate remedy, and better still a means of prevention, can 

 be suggested. 



In a paper which appeared in Phytopathology, vol. v., 

 No. 4, August 1 915, Mr Arthur H. Graves makes a valuable 

 contribution to our knowledge of coniferous seedling disease. 

 The author first points out the injurious influence of faulty 

 soil t'eration on the health and growth of old trees. He then 

 goes on to say : " The disease in question appeared in the 

 nursery of the Yale Forest School during the spring and early 

 summer of 19 14, and was particularly destructive. Besides 

 the loss of about twenty per cent, of a bed of one-year-old red 

 pines, Finns rcsiiiosa, Ait., and five per cent, of a bed of one- 

 year-old white pines, Finns strobus, L., several thousand two-year- 

 old red pines succumbed, as well as a few seedlings of one-year- 

 old hemlock, Tsuga canadensis (L.), Carr. 



" The disease first became noticeable through a dark red or 

 reddish-brown coloration of the tips of the leaves. In the 

 initial stages the contrast of this dark red colour with the 

 remaining deep green of the leaves was very striking. By 

 slow degrees, extending over an interval of several weeks, the 

 red colour extended throughout the entire leaf to its base. 

 Subsequently the reddish hues changed, usually to browns or
