along with seed to any appreciable extent. — Spraying was continued in orchards in Kumaon 

 (outer Himalayas). — Identification of, and inoculation experiments in, Fusarium, Ilelmin- 

 thosporium, Acrotheciwn, and Rhizoctonia diseases of cereals is in progress. — Rot in stored 

 potatoes appears to be due to excessive temperature, and not primarily to fungous inva- 

 sions. — A root rot of cotton (Gossyjniwi) appears to be associated with some unknown soil 

 conditions. — A fungous flora of India is in preparation. "The total number of recorded species 

 is probably under 2000, which is certainly not one-fourth of those that exist." — The report 

 closes with a program for work in 1920-21, and a list of publications for the 3^ear. — Winfield 

 Dudgeon. 



391. NowELL, W. A disease of coco-nut. Imp. Dept. Agric. West Indies Rept. Agric. 

 Dept. St. Lucia 1918-19: 7. 1920. — Diseased specimens when received by the author were 

 in bad condition; nevertheless a phycomycete resembling Pyihivrn or Phyto]>hthora was 

 much in evidence on the central shoot and unexpanded leaflets. Because of parasitic habits 

 of this group, this organism is suspected of having etiological relationships. Question arises 

 whether this fungus is related to Pythium pabnivorvm, the bud-rot organism of the East 

 recently suspected of causing coconut disease in Jamaica. Fructifications in the St. Lucia 

 fungus are round or nearly so, and resemble the zoosporangia of Pythium deBaryanum more 

 than do the pear-shaped Phytophthora-like sporangi of Pythium palmivorum and the Jamaica 

 species. Further investigation is needed. Meanwhile, Bordeaux or Burgundy mixture, 

 preferably with milk or resin soap to increase adhesion, is recommended for controlling the 

 disease. — J. S. Dash.

 rhododendron. Phytopathology 10: 273-278. 11 pi. 1920.— The important diseases of the 

 rhododendron on the Pacific coast are summarized as follows: Sporocyhe azaleae, Melampsor- 

 opsis piperiana, witches' brooms, white leaf, Lophodermium rhododendri, Coccomyces dentatus, 

 Coryneum rhododendri, Sphaerella rhododendri, Pestalozzia guepini, and Cryptostictis sp. 

 The symptoms of all these diseases are described and control measures are suggested for 

 some. — Ruth G. Bitterman.

 in Deutschland. [The potato wart, a peculiar new potato disease in Germany.] 8 p., 5 fig. 

 P. Parey : Berlin, 1918. — (Mitteil. K. Marine-Intendantur, Wilhelmshaven.) — A circular for 

 the practical gardener and farmer giving the history' and distribution of the potato wart dis- 

 ease in Germany, and an account of the life history of the pathogene. Emphasis is placed 

 on the fact that this disease may become a serious factor in field potato culture although it 

 is now restricted to home gardens in industrial centers where continuous potato culture is 

 practiced and field sanitation unknown. Recommendations for preventing its further spread 

 are given and the experience of England with the potato wart disease is cited as a warning 

 to Germany. — The spread of initial infection is thought to be due to penetration of the deeper- 

 lying tissues by swarm-spores liberated in the superficial tissue layers. The finding of 

 sporangia in the base of an epidermal hair is reported. — F. Weiss.

 ampelopsorae on grape, Sclerotinia libertiana on carrot, lettuce bacteriosis, and Phytophthora
