Report of the spread of Phylloxera vastatrix in Austria during 1898-99 

 (Bericht uber die VerbreUung der Reblaiis in Osterreich in den Jahren 1898-99. Vienna: 

 Ministry of Agriculture, 1900, pp. 170, map 1). — This pamphlet contains the reports of 

 fruit inspectors and horticultural experts on the condition of phylloxera in different 

 parts of Austria. Numerous tables are given showing the localities infested, the 

 extent of such infestations, and the rapidity of distribution of the phylloxera in 

 different localities. During the year 1898-99, 190 new localities were found to be 

 infested. The distribution of the insect progressed much more rapidly in 1899 than 

 in 1898 on account of the dryness of the former year. The chief remedy against the 

 phylloxera is bisulphid of carbon, of which increasing quantities are purchased from 

 year to year. During the 2 years in question 12,376,000 American grape roots and 

 scions were received for planting.

 the adult beetles.

 decoctinn are reconnnended.
