miira) ; Inasa-gun, Iinoya-mura, April 13, 1914, S. Tsuruda; 

 Aratama-mura, May, 1914, T. Okada. 



New Japanese name of the disease: Mugi no Kangare-byo 

 (Culm-rot disease of barley and wheat). 



Local name of the disease: Mugi no Tachigare (Foot-rot or 

 stem-rot of barley and wheat) ; Kuse (Bad-habit). 



Notes : A barley variety " Dobu " seems resistant to the disease ; 

 on the other hand the variety " Oku-mikawa " is very susceptible. 

 The disease is much less injurious when seeds are sown earlier 

 than the usual planting time. The disease becomes virulent when 

 nitrogenous fertilizers are used too freely. Phosphate is effective 

 in strengthening the growth of the culm to withstand the disease. 

 Lime, sulphur-flower, and Bordeaux mixture all lessen the 

 damage done by this fungus.

Mycelia covering the upper surface of the leaves of Thea 

 sinensis as a black mass, sometimes covering the lower surface 

 and even the twigs, presenting a conspicuously rough or fuzzy
