2068. Miovi6 and Anderlic\ Uber Tomatener krankungen. [Tomato diseases.] Zeit- 

 schr. landw. Versuchsw. Osterr. 21:407-415. 191S. — Phytophthora infestans and Gloeosporium 

 phomoides attacked tomatoes in Dalmatia. The latter fungus attacked only the variety 

 Ficarazzi causing wrinkled, unmarketable fruit. The diseases were controlled by 4 applica- 

 tions of 1 per cent Bordeaux mixture the first applical ion being made in the hot-bed. [Through

 of walnut (Juglans regia).] Bull. Soc. Path. Veg. France 6: 134-136. PL 1, 6 fig. Nov.- 

 Dec, 1919. — Nuts of Juglans (cultivated) from certain trees show thin places or irregular 

 lesions penetrating the shell. No insect or fungus was associated with the trouble and it is 

 regarded as a physiological disorder or degeneration. It is confined to certain trees which 

 show the disease each year. — C. L. Shear.

 17: 49-51. 1918. — Review of facts concerning overwintering of Puccinia graminis and role of 

 barberry in its perpetuation and dissemination. Suggests that critical study be made before 

 restrictive measures of the more northerly countries are adopted in Hungary. [Through abst.

2073. Nicholls, H. M. Annual report of the Government Microbiologist. Tasmania Agric. 

 and Stock Dept. Rept, 1916-17: 20-23. 1917. [Appeared, 1918.]— "Owing to the phenome- 

 nally wet season, fungous diseases of all kinds were very common in fruit and other crops." 

 Apple scab, "powdery mildew or fire blight," black rot (Sphaeropsis malorum) abundant and 

 destructive on apples. Puccinia pruni injured stone fruits, generally, including apricots; 

 Coryncutn beyt rincki also was injurious to stone fruits causing shot-hole. Potato blight 

 [ Phytophthora] was widespread and losses ranged up to 100 per cent. Experiments for the con- 

 trol of a pea disease, caused by Rhizoctonia, are reported but were practically without result 

 owing to wet weather. Peronospora viciae does some damage to peas. — Iron sulfid spray gave 

 satisfactory control of apple mildew. [See also next following Entries, 2074, 2075.] — D. 

 Reddick. 



2074. Nicholls, H.M. Annual report of the Government Microbiologist. Tasmania Agric. 

 and Stock Dept. Rept. 1917-18: 13-16. 1918. — Diseases much less prevalent than previous 

 year on account of dry season. In addition to notes on apple diseases and potato blight, 

 Fusarium solani is reported as the cause of a destructive potato wilt. [See also next preced- 

 ing and next following Entries 2073, 2075.] — D. Reddick. 



2075. Nicholls, H. M. Annual report of the Government Microbiologist. Tasmania 

 Agric. and Stock Dept. Rept. 1918-19: 20-23. 1919. — Oidium lactis has been found to cause 

 rancidity in butter. Slow pasteurization of cream is effective in prevention. — Potato tubers 

 were subjected to a temperature of 125°F. for 4 hours to kill Phytophthora. When planted, 

 they sprouted sooner and more evenly than untreated tubers and made a better crop. Owing 

 to the dry season late blight did not develop in the field. Early blight (Macrosporium) , wilt 

 (Fusarium), scab (Rhizoctonia), scurf (Spondylocladium) , potato moth, and eel-worm were 

 prevalent on potato. Rhizoctonia of potato also injures field pea. Fruit diseases occurred 

 as in 1916-17 (see second preceding entry) but were not so serious owing to dry season. — Young 

 apple trees which suddenly wilt and die were found affected with a fungus "identical in every 

 respect with Fusarium vasinjectum." Action of fungus seems to he purely mechanic:! 1 (throm-
