Bos, J. Ritzema. De klaverkanker, eene zich meer en meer uitbreidende klaver- 
ziekte. <Wageningen, May 16, 1892, pp. 13. 
Contains a general sketch ol the canker, which affects Trifolium pratense especially, due 
to Sclerotinia trifoliorum. Besides a description of the lite history of this fungus, the author 
gives some statements as to the eradication ot the disease, and recommends digging out the 
infested parts of the clover field and burning the plants in a pit which has been partly 
filled with quicklime. 1 he disease has been observed in several places in Holland, 
especially in Groningen, Zeeland, and North Brabant. (T. H.)

ir, Sydney, Oct., 1891, pp. 616-624, pi. 2, figs. 5. 
Gives notes on diseases of plants, as follows: Onion mildew, caused by Peronospora 
schleideniana, and for which Bordeaux mixture is recommended; tobacco mildew, caused by 
Peronospora hyoscyami ; potato blight, murrain, or rot, caused by Phytophthora infestans, 
although not yet known in thecolony, is fully described so that it may be known if it should 
appear. Bordeaux mixture is given as one preventive, clean culture and high molding 
being others; and banana disease, the cause of which is unknown, but may be due to a 
fungus attacking the roots. Mention is also made of the occurrence of bread mold on 
oranges, supposed to be caused by injury to the fruit. (For portion relating to diseased 
banana plants, see Bull. Bot. Dept. Jamaica, No. 31, May, 1892, p. 2; also, under title of

Describes the various forms ot smut ot cereals; caused in oats by TJstilago avence,- in 
wheat by l . tritici , Urocystis occulta , and Tilletia foe tens ; also describes smut in maize. 
Gives various methods of treatment, mainly hot water and “ Milestone. ’ These last are 
recommended for all the smuts. (J. F. J.)

Refers to disease of fungous origin affecting leaves of coffee. In appearance the disease 
resembles potato rot. The namo of the fungus was not determined. (J. F. J.)

States that specimens sent from Trinidad affecting sugar cane belong to a species to be 
described as Trullula■ sacchari Ell. & Ev. Says also that a bacterial disease may be present, 
but of this there is as yet no absolute proof. (J. F. J.)

Notes the occurrence of Peronospora hyoscyami in Australia, where it attacks tobacco 
leaves. Describes the appearance of the fungus, and suggests burning all diseased plants. 
Does not believe spraying with fungicides would be of any benefit in checking the disease.

States the disease is caused by Golletotrichumlindemuthianum. Describes general appear¬ 
ance of affected seed, and says that those showing disease did not germinate as well as 
healthy seed, and the plants were diseased. Advocates soaking seed in solution of 3 ounces 
of carbonate of copper, 1 quart of ammonia water, and 4§ gallons of water. (J. F. J.)

Describes celery blight or “rust” as caused by Cercospora apii , giving an account of suc¬ 
cessful treatment with ammoniacal copper carbonate solution; celery leaf-spot due to Phyl- 
losticta apii n. sp; another leaf-blight, due to Septoria petroselini x ar. apii; celery rust 
, proper, due to Puccivia bullata; and a bacterial disease of celery that attacks and destroys 
the hetirts of the plants. It is though* that ammoniacal copper carbonate solution can be 
successfully used for all three diseases (see also Am. Agr., July, 1892, vol. li, pp. 426-427; 
Exp. Sta. Rec., vol. in, July, 1892, pp. 884-885). (J. F. J.)
