DISEASES OF PLANTS. 



Four new fungus diseases in Iowa, L. H. Pammel and Charlotte M. King 

 (loica Sta. Bill. 131, pp. 199-221, figs. IJ,). — Notes are given on timothy rust 

 (Puccinia phlei-pratensis) , alfalfa rust (Uromyccs striatus), blister canker of 

 the apple (Xummularia- discreta), and onion smut (Urocystis ccpulw). The 

 different fungi and their methods of attack are described, and accounts are 

 given on the distribution of the diseases and the relation of the fungus to the 

 host plant, together with suggestions for their control. A bibliogi-aphy is 

 appended. 



Notes on fungus diseases, J. C. Moore (Rpts. Bot. Sta. [etc.] St. Luoi<v, 

 1910-11, pp. 6, 7). — Brief accounts are given of diseases affecting a number of 

 economic plants, among them the root disease, which attacks cacao, breadfruit, 

 avocados, and other trees ; the pink disease of guavas, due to a fungus which 

 has been identified as Coiiiciiim Icrvc; and a fungus disease of lime branches, 

 which is caused by attacks of Thelephora pedicellata. 



Fungi exotici: XIII, G. Massee {Roy. Bot. Gard. Ketv, Bui. Misc. Infonn., 

 1912, No. If, pp. 189-191). — The author describes a number of species of fungi, 

 two of which are considered to be injurious parasites. These are PhcangcUa 

 hevew, which is found on the bark of the young Hevea rubber trees in Southern 

 Nigeria, and Collrtotrichum necator, which is said to cause the fruit of peppers 

 to become blackened and shriveled. Technical descriptions of the different 

 species are given. 



The seed treatment of summer grains, L. Hiltner (Prakt. Bl. Pflanzenbau u. 

 Sclnitz, n. ser., 10 (1912), No. 2-3, pp. 23-26). — The author recommends treat- 

 ing oats, barley, and wheat with a 0.1 per cent solution of formalin for the 

 prevention of loose smut of oats, stinking smut of wheat, and barley smut 

 due to Ustilago hordei. Other efficient treatments recommended are the use of 

 Sublimoform and Cuproform, combinations of corrosive sublimate and formalin 

 and copper sulphate and formalin. For the treatment of rye a weak solution of 

 corrosive sublimate is preferred. For combating loose smut of wheat and 

 barley chemical treatments can not be recommended, but the modified hot-water 

 treatment is said to be very efficient. 



Control of grain smuts, Johanna Westfrdijk (Cultura, 23 (1911), No. 280. 

 pp. 558-598). — This is a discussion of the present state of the information re- 

 garding combating of smut in grains, and of the recent literature on the sub- 

 ject. Attention is given more particularly to the contributions of O. Appel 

 and E. Eheim (E. S. R., 26, p. 546) on the treatment with hot air and hot 

 water under conditions claimed by them to produce the best results. The 

 author states that this treatment has already been successfully employed in the 

 Netherlands.
