1062 EXPERIMENT STATION RECORD. 



usually attributed to attacks of fungi, several species of which are enumerated, but 

 the author believes root galls cause considerable of the trouble. The origin of the 

 galls is thought to be due to some small eoleoptera. 



A new bla&tomycete parasitic on the fruit of the filbert, V. Peglion (Alti B. 

 Accad. Lincei, 294 (1897), p. 276). 



A disease of pears, J. Normant (Monit. Vin., 1897, No. 95, p. 378). 



Concerning potato rots, E. Rozk (Compt. land. Acad. Sci. Paris, 125 (1897), No. 

 25, pp. 1118-1120). —The author considers the potato rots under 2 divisions, the dry 

 rotadueto Psetidocommisvitis and Micrococcus spp., and the wet rots due to Micrococcus 

 sp. associated with Bacillus subtilis and to PhytopJithora infestans. 



Insect and fungus pests of potaioss, II. Garman (Kentucky Sta. Bpt. 1896, pp. 

 14-35, figs. 7). — A reprint from Bulletin 111 of the station (E. S. R., 8, p. 136). 



A bacterial disease of sweet corn, F. H. 11am. ( New York State Sta. But. 130, pop- 

 ular ed., pp. 5, pin. 2). — A popular summary of Bulletin 130 of the station (seep. 1056). 



On lust on the small grains, .(. Smitt ( Tidsskr. Norske Landbr., 4 (1897), No. 10, 

 pp. 441-445). — A resume" of J. Eriksson's results. 



A new disease of wheat in Sardinia, A. N. Beiilese (Bol. Not. Ayr., 19 (1897), 

 No. 13, pp. 430-437, figs. 2). — The author gives the life history of the fungus, Spluero- 

 derma damnosum , and an account of successful infection experiments. Ordinarily the 

 fungus is saprophytic, but under some circumstances may become a destructive 

 parasite. 



The wheat eel {Sachs. Landw. Ztschr., n. ser., 19(1897), No. 34, pp. 480, 481, figs. 3).— 

 This nematode ( Tylenchus scandens), whir]) is from 0.8 to 1 mm. long, is found in the 

 kernels of matured wheat, where it produces what is called "rade korn," which is 

 without the power of germination. The only remedy noted is the sifting out of the 

 diseased kernels. 



An experiment with apple rot in 1896, H. Garman (Kentucky Sta. Bpt. 1896, 

 pp. XXXIV-XXXVI, pi. 1). — Notes are given on an experiment with Bordeaux mix- 

 ture applied to .Janet apple trees for the prevention of rot of the fruit. Two trees 

 were selected, one being used as a check. Eight applications were made. The 

 weight of sound apples from the sprayed tree when the fruit was gathered, Septem- 

 ber 26, was 62 lbs. 4 oz., while those from the unsprayed tree weighed 8 lbs. 6 oz. 

 As the result of the treatment the total yield of sound apples was increased more 

 than seven times. 



Results of experiments conducted in 1896 for the control of grape Peronos- 

 pora, G. CUBONl | Bol. Not. Agr., If* (1897), No. 12, pp. 401-411). -The results of exper- 

 iments conducted in a large number of vineyards with various fungicides are 

 reported. Bordeaux mixture, acetate of copper, sulphosteatite, copper-soda mix- 

 tures, copper sucrate, borol, etc., were tested with a view to securing some substi- 

 tute for Bordeaux mixture. The results were negative in many cases and in others 

 ■were very inferior to Bordeaux mixture. The experiments are to be repeated. 



Influence of fertilizers on the disease and injuries of grapevines, P. Coste- 

 Floret (Prog. Agr. et fit., 29 (1898), No. 10, pp. 300-308). 



Report of experiments for the prevention of black rot of grapes, Marre and 

 FouRNlALis (Prog. Agr. et fit., 29 (1S9S), No. 6, pp. 1S3-188). 



On the use of corrosive sublimate against black rot, L. Degrully (Prog. Agr. 

 et Fit., 29 (1S9S), No. 1 .'. pp. 353-355).— This fungicide is said to be as efficient as 

 copper compounds for the prevention of black rot. 



On the preparation and use of bichlorid of mercury solutions as fungicides, 

 L. Degrully (Prog. Agr. et Fit., 29 (189S), No. 10, pp. 289-292). 



Best remedy for gooseberry mildew, P. II. Hall (New York State Sta. Bui. 133, 

 popular ed., pp. 6). — This is a popular summary of Bulletin 133 of the station (see 

 p. 1061). 



Oat smut and new preventives, F. H. Hall (New York State Sta. Bui. 131, popu- 

 lar ed.,pp. 6). — This is a popular summary of Bulletin 131 of the station (see p. 1060). 



Formic aldehyde, G. L. Taylor (Amer. Jour. Pharm.,70(189S),No.4, pp.195-201).— 

 Notes are given on the preparation, analysis, and uses of this important germicide.
