 Acad. Sci. 20: 351-352. PI. 28. 1918.— A description of a soft rot disease observed in 1917 

 on pepper plants growing in the Horticultural plots of the Michigan Agricultural College. 

 Experiments were made in order to compare the pepper rot organism with Bacillus carotovorus. 

 which had been suggested as the causal organism. There was no apparent difference between 

 the rot symptoms produced by the pepper rot organism and those produced by laboratory cul- 

 ture of Bacillus carotovorus. As a result of these experiments the writer concludes that the 

 pepper may be listed among the many hosts of Bacillus carotovorus. — J. Norma Anderson.

745. Brandes, Elmer W. Distribution of Fusarium cubense E. F. S., the cause of 

 banana wilt. Rept. Michigan Acad. Sci. 20: 271-275. 1918. — The author gives a report of 

 observations in American banana countries north of the equator. He concludes that the banana 

 wilt organism, Fusarium cubense, which he has already shown to be pathogenic (Ann. Porto 

 Rico Agric. Exp. Sta. 1916:29-31), exhibits biologic specialization in the several countries 

 visited thus accounting for the observed relative susceptibility of a given variety grown in 

 different countries. Observations are reported also on the relation of climatic conditions 

 to the prevalence of the disease in various countries. Sustained wet weather favors the para- 

 site while dry weather is unfavorable. — L. R. Hesler. 



746. Brittlebank, C. C. Tomato diseases. Jour. Dept. Agric. Victoria 17: 231-235. 

 1919. — A new tomato disease, "spotted wilt," first found in 1915-16, has proved disastrous in 

 1918-19 in Victoria. The attack is first on the new terminal leaves. Brown and blackened 

 areas scattered between the larger veins appear. The author states that it is the same dis- 

 ease that occurs in America (Phytopathology 6: 162. 1919). Examination failed to disclose 

 a causal organism, and inoculation experiments gave negative results. Experiments on 

 sterilized soil suggest that the disease might be due to some chemical or physical deficiency 

 in the soil. — J. J. Skinner.
