Tobacco .showing leaf spots pi-oved to be affected by Cercospora rueiborskii. 

 Yams are attacked by a leaf disease caused by Glceosporium pestis. A leaf spot 

 of sisal plants was found to contain Macrosporium lanceolatum. Leaves of 

 cloves bearing reddish or purplish marks, at the Nasinu station, showed a 

 Peronospora. Jute showing a leaf spot yielded a Cercospora. A tomato wilt 

 could not be traced to any definite cause. 



Kentia macarthurii showing a leaf spot yielded a Pestalozzia. A comparison 

 is made of the spores of the forms of this fungus found on Hevea and Kentia 

 leaves and on ripe fruit of Garcinia. A disease of Livistonia was associated 

 with Graphiola phmnicis. Licuala grandis showed brown intervenous areas 

 associated with a Colletotrichum. Hose leaves were attacked by Actinonema 

 rosw. Cassm fistula was apparently attacked by a fungus which was not 

 classified. 



Several weeds are named as being attacked by fungi. 



Report of the imperial mycologist, F. J. F. Shaw (Ann. Rpts, Expert Offs. 

 Bept. Ayr., Bengal, 1915, pp. 1^4, H5). — It is said that experiments looking to 

 the control of ufra disease have been only partly successful. A disease of betel 

 vine occurring near Bogra was found to be caused by Rhizoctonia destruens, 

 particulars regarding which are to be given in a memoir now in press. Autlirac- 

 nose of betel is said to be a different disease, the causation of which is obscure. 

 Potato blight was studied and the results are to appear later. A disease of 

 areca palm may be due to a form of Fomes lucid us. 



Beport on the first two years' working of the plant protection law (Law 

 No. 5 of 1913), G. Storey (Mm. Agr. Egypt, Tech. and Sci. Serv. Bui. 1 

 (1916), pp. 37). — This contains an account of the legislation for plant protec- 

 tion in force prior and subsequent to the formation of the Department of Agri- 

 culture of Egypt in 1911, and of the action as taken in cases arising thereunder ; 

 also an appendix giving the new law of 1916, which supersedes the law of 

 1913. 



Besides giving an account of insect pests found in or on plants offered for 

 importation, mention is made of infestation by such parasites as Cladospormm 

 citri on oranges from Syria, Veiitui-ia porni on apples, ScJerotinia fructigena 

 causing a brown fruit rot on peaches from Italy, and Tylenchus tritid, which, 

 however, is already present in Egjpt on wheat. 



Studies on a Fusarium disease of corn and sorghum, L. H. Pammel, Char- 

 lotte M. King, and J. L. Seal (Iowa Sta. Research Bui. S3 (1916), pp. 115-136, 

 figs. 15). — A preliminary report is given of a study of a Fusarium disease of 

 corn which is said to have made its appearance in Iowa during 1914 and which 

 was again abundant in 1915, causing a large estimated loss. The fungus attacks 

 the roots, stalks, and ears of the corn. The effects on the different parts of 

 the plant are described, and the results of a study of the organism are given. 



The fungus causing the disease is definitely referred to a species of Fusarium, 

 and in connection with the trouble the perithecia of Gibberella has been found, 

 but the authors liave not been able to show that this fungus has any relation 

 to the Fusarium. The disease is believed to be spread largely through the seed 

 corn, and cai-eful selection of seed is recommended as a preventive measure. 



A Fusarium disease of sorghum, which is similar to, if not identical with, 

 that on corn, is also described. 



Clover sickness, A. Amos (Jour. Farmers' Club [London], 1916, May, pp. 

 61-76). — This is an account, with discussions, of observations on clover sick- 

 ness, which is ascribed to the presence of Sclerofinia trifoUorum or of Tylenchus 

 devastatrix, or of both. Several remedies are discussed, but it is thought that 

 clover may be protected from both of these enemies by the same general prac-
