Disease situation in Indian forests. 1. Stem diseases of some exotics due to Corticium salmonicolor and Monochaetia unicornis.
Describes and illustrates the symptoms of attack and fungal stages observed on infected trees, predisposing factors and control measures. C. salmonicolor has caused <more than>50% mortality in Eucalyptus globulus 2-5 years old in N. and W. Bengal, and has been reported causing twig blight in Populus 'I-214' and 'I-488', Podocarpus gracilior and isolated trees of Casuarina montana at Dehra Dun. M. unicornis is recorded as a canker on Cupressus arizonica [cf. F.A. 28 No. 5897], C. lusitanica and C. sempervirens at Dehra Dun. C. cashmeriana in this region, appears to be free of the disease.
