DISEASES OF PLANTS. 



The fungus diseases of agricultural plants, J. Eriksson, trans, by A. Y. 

 Grevillius (Die PUzkrankheiten dcr landwirtschaftlichen KuUurpflanzen. 

 Leipsic, 1913, pp. XVI -{-246, pis. 3, figs. 130). — This is a German edition of a 

 book previously noted (E. S. R., 28, p. 345). 



Annual report on plant diseases, 1911, M. Hollrung (Jahresber. Pflanzen- 

 krank., 14 (1911), pp. Yin-\-410). — This report, published in 1913, continues the 

 general plan of its predecessors (E. S. R., 28, p. 345), the literature cited for 

 1911 including 2,360 titles. 



A preliminary host index of the fung-i of Michigan, exclusive of the 

 Basidiomycetes, and of the plant diseases of bacterial and physiological 

 origin, G. H. Coons (Rpt. Mich. Acad. Sci., 14 (1912), pp. 232-276).— Lists are 

 given of parasitic fungi observed as occurring on various host plants in 

 jSIichigan. 



Report on the work of the phytopathologist at Wageningen for 1911, 

 J. RiTZEMA Bos (Meded. Rijks Hoogere Land, Tuin en Boschhouivsch. [Wage- 

 ningen], 6 (1913), No. 3, pp. 105-163). — This is an account of observations and 

 experiments reported in relation to plant disorders due to inorganic agencies, 

 attacks by plant or animal enemies, or undetermined causes. 



Report of the botanical laboratory and laboratory for plant diseases, L. 

 Linsbauer, F. Zweigelt, and H. Zuderell (Programm u. Jahresher. K. K. Hoh. 

 Lehranst. Wein u. Ohsfbau Klosfemeu'burg, 1912-13, pp. 159-178, figs. 3). — A 

 report is given on various investigations on plant diseases and insect pests, to- 

 gether with means adopted for their control. The principal investigations were 

 carried on with those pests attacking orchard fruits, grapes, berries, potatoes, 

 vegetables, and ornamentals. 



Plant diseases observed in 1912 at the agricultural academy at Kolozsvar, 

 B. Grof (Kiserlet. Kozlem., 16 (1913), No. 2, pp. 271-277, pi. l).—Phoma 

 fceniculina is reported from the same locality as in the previous year. Puccinia 

 malvacearum is said to infest not only AWicea rosea nigra, but also seriously A. 

 officinalis in the neighborhood and sporadically Malva sylvestris and M. vul- 

 garis rotundifolid, which are suspected to constitute a medium for the probable 

 adaptation of this fungus for living on A. officinalis. Plasmopara nivea was noted 

 on leaves of Conium maculatum living through the winter, appearing about 

 May 15 and showing oospores about August 15. Puccinia Mllata appeared 

 about the same time on leaves, petioles, and twigs of the same host, showing its 

 fruiting bodies about the same time and evidently inflicting considerable injury. 



Agricultural botanical notes from the experimental plats at Ultuna, 1912, 

 E. Henning (Sveriges Utsadesfor. Tidskr., 23 (1913), No. 2, pp. 129-141, fig- 

 1). — Discussions are given of the development of the winter wheat plants in the 

 late fall of 1911, the size of leaves of the wheat varieties at time of blooming, 

 mealy and glassy winter wheat kernels, the appearance of yellow and black rust 

 (Puccinia glumarurn and P. graminis) on small grains, and infection experi- 

 ments with loose smut of barley (Ustilago nuda). 



A contribution to the mycological flora of Russia, N. Naoumoff (Bui. 

 Trimest. Soc. Mijcol. France, 29 (1913), No. 2, pp. 273-278, pi. 1; ads. in Internat. 

 Inst. Agr. [Roine], Mo. Bui. Agr. Intel, and Plant Diseases, 4 (1913), No. 7, 

 p. 1115). — Preliminary to publication of a fuller list of collections in Russia, 

 the author notes three species of fungi obtained in the summer of 1912, which 

 are described under the respective names of Bremia graminicola n. sp. (on leaves 

 of Arthraxonis ciliaris), Cicinnotolus hremiphagus n. sp. (pycnidia of which 

 were attached to fruiting organs of B. graminicola) , and Rhodoseptoria ussurien- 

 sis n. g. and sp., destroying leaves and fruit of the Manchurian plum.
