(4) Experiiiiciits for the control of grape-rot. — Extensive experi- 

 ments have been conducted in a vineyard in the Seneca Lake region, 

 having for their purpose the control of the black-rot of grape. 

 Supplementary experiments have been conducted in Yates county for 

 the suppression of the same disease. These experiments have been 

 carefully planned by the writer in conjunction with Assistant Pro- 

 fessor Wilson, under whose direction the work has been prosecuted. 

 Grape-growers have suffered heavily in recent years from the 

 ravages of this parasite, and it is gratifying to be able to state that 

 these experiments indicate that the loss may be obviated in large 

 measure by vineyard sanitation and the application of the copper 

 salt sprays. 



(5) Bordeaux injury. — An investigation of the injury of apple 

 foliage and fruit resulting from spraying with Bordeaux mixture 

 was made during the year, but without definite results.
