Petch, T., A Bark Disease ofHevea, Tea etc. (Circulars and 

 Agric. Journ. ro3^al bot. Garden, Ceylon IV. 21. July 1909. p. 

 189-196.) 



Corticinn javaniciun, Zimm., or someother closely aliied if not 

 identical species, causes throughout the tropics a bark disease cha- 

 racterised by the production of superficial pink patches of fungus 

 tissue. In Ceylon C. javaniciun attacks Hevea, Tea, Cinchona and 

 Plum, the present circular dealing with the disease on the first two 

 plants. On Hevea a pink incrustation is formed on the branches, 

 the hyphae gradually penetrating and killing the bark; the wood is 

 scarcely injured but the dead bark peels off and an open wound 

 or canker results. The disease usually appears in a fork of the tree, 

 or in places where a roughness in the bark retains moisture. Cut- 

 ting out infected areas and tarring the wound is recommended. 



Tea suffers mostly in up-country estates, the disease appearing 

 regularl}^ towards the end of the S. W. monsoon. Twigs and young 

 branches are attacked. The fungus dies away in dry weather, and 

 the evidence points not to a continuous infection from the cankered 

 patches but to reinfection from external sources. Old wounds should 

 however be tarred to arrest further decay. A. D. Cotton (Kew).
