148 EXPERIMENT STATION RECORD. 



was tested. As each plant was set a tablespoon fill of sulphur was 

 placed around the roots. Five rows across a field were treated in this 

 way, and 5 with a considerable space between them were left as checks. 

 The results of the experiments indicated that sulphur applied in this 

 way had a decided effect in diminishing the black rot. The loss on the 

 check rows was so slight, however, that it scarcely paid for the trouble 

 and expense of treatment. 



Treatment of leaf spot in plum and cherry orchards in 1896, 

 S. A. Beach (New York State Sta. Bui. 117, pp. 133-141).— This 

 work, which is in continuation of that given in Bulletin 98 of the 

 station (E. S. K., 8, p. 139), was conducted to investigate the means 

 for the control of the leaf spot on plums and cherries. Since the pre- 

 vious work showed that 3 applications of Bordeaux mixture were 

 sufficient to control the disease, experiments this year were conducted 

 to ascertain the proper time for their application. With plums it 

 appears that if but 2 or 3 treatments are to be made the first should be 

 given during the last week of May, or about 10 days after the petals 

 fall; the second about 3 weeks later, and the third about 3 or 4 weeks 

 after the second application. When the disease is no more prevalent 

 on plums than it was during the summer of 1896, 2 sprayings, applied 

 as described above, will practically prevent all injury. 



The experiments with cherries were conducted to test the efficiency 

 of eau celeste, soap mixture, and Bordeaux mixture. In general in 1895 

 the foliage of the cherry trees was injured by applications of eau 

 celeste mixture, but in 1 group of Keine Hortense cherries the Bor 

 deaux mixture caused the greater injury. In the spraying experiments 

 conducted in 1896 no injury was apparent on the leaves as a result of 

 the sprayings, even though the trees were thoroughly drenched with 

 Bordeaux mixture. When the Bordeaux mixture is applied as late as 

 May 25, it is very liable to show on the fruit and injure its appearance.

Black rot and resistant varieties of vines, F. Cotjderc-Mimerel (Prog. Agr. et

 efficient in preventing hlack rot and that attention should be turned to resistant 

 varieties.
