846 EXPERIMENT STATION RECORD. 



trouble had become serious in lOon, and at the time of the authors' visit in 

 1906 it was found that many of the vines had died. In some cases the old 

 roots had put out sprouts, some of which were wiltini;. and in some instances 

 new vines had been planted in place of the old ones. 



The wilting of the vines is a conspicuous character of the disease, the leaves 

 and tender shoots first showing by their wilting that the disease is present, 

 after which they droop and finally dry up, while the berries are shriveled. In 

 studying the winter condition of the disease the authors found that if the old 

 Itark is stripped off the diseased stems, on the inner bark will be found rows of 

 lilack dots arranged more or less in longitudinal elevations. 



A study of specimens showed that they were identical with the parasite 

 reported by Atkinson in New York in lOO-l and referred by him to a form of the 

 grape anthracnose. 



While investigating this disease the authors found that it was also present 

 in a 13-year-old vineyard at the station. This vineyard had been regularly 

 and thoroughly sjtrayed with Bordeaux mixture, followed by animoniacal cop- 

 per carbonate, but the presence of the disease seems to reflect against the 

 efficacy of Bordeaux mixture alone as a remedy against this disease. 



Based upon investigations carried on in Europe and elsewhere, the authors 

 reconunend the spring treatment of all vines with a solution of iron sulphate, 

 fulphuric acid, and water. As a precautionary measure it is recommended that 

 diseased portions of vines be cut out and burned. 



In order to study more thoroughly the distribution of the fungus, the authors 

 request correspondence relating to it and ask that siispected specimens be sent 

 them. 



A mulberry disease in Kashmir, E. J. Butler (Agr. Jonr. India. 2 (1907), 

 No. 1, pp. 97, 9S). — An account is given of a serious disease of mulberries 

 which has not previously been recorded in India. The disease is found in old 

 trees without causing appreciable damage, but great harm is done to young 

 plants in nurseries, a fungus attacking the seedlings in their second or subse- 

 quent years. It is said not to kill the seedlings outright, but as the affected 

 plants have to be cut back below the diseased parts, several years' growth is lost. 



The disease is said to be caused by the fungiis Corijiieum mori. which invades 

 the wood and young branches and results in the withering of the branches, 

 which drop their leaves. 



This disease is already known in Japan, and it is possible that it was intro- 

 duced into India from that country. How serious it is likely to prove it is as 

 yet impossible to predict, as methods for its control are not known. 



The coffee nematode, G. Gandara (Com. Par. Agr. [Mexico] Circ. 51, pp. 7, 

 figs. 6). — A desc-ription is given of attacks of Heterodcra radiclcolu on coffee, 

 and attention is called to the loss which this nematode has caused to coffee 

 plantations in Brazil and elsewhere. The eff'ect on the host plant is noted, 

 after which various cultural remedies are described. In addition to methods 

 of cultivation that are based upon stimulating the growth of the trees, it is 

 suggested that various substances be injected about the trees for the destruction 

 of the nematodes. Among those mentioned are gasoline, benzine, iron sulphate, 

 carbon bisulphid, sulphocarbonate of potassium, etc. 



A good method for combating Pestalozzia palmarum on cocoanut palms, 

 C. Bernard (TcgKiiiaiuiia, 17 {I'.XJIj), Xu. 10. pp. ().J.'i-657) . — For pnnenting the 

 spread of P. palmar u in on cocoanut trees the author recommends a treatment 

 which has been found eflicient on an estate in Java. This consists in cutting 

 out the diseased portions of the tree as soon as the fungus spots appear and 

 burning or deeply burying the material. The author adds the precaution of
