Spraying Potatoes for the Prevention of Blight and Rot, 



Although it has been known for about seventeen years that spraying with Bor- 

 deaux mixture "will prevent the blight and rot of the potato, only a small proportion 

 of Canadian farmers spray even yet, although the loss is very great nearly every year. 

 This year a comparative test was made between plots sprayed with Bordeaux mixture 

 and Bug Death applied together; Bordeaux mixture and Paris green; Bordeaux mix- 

 ture made with washing soda instead of lime, and Paris green ; Bug Death ; and Paris 

 green. Sixteen varieties were used in this test, each occupying one row 33 feet long, 

 the 16 varieties covering lust 1-33 of an acre being the area devoted to each test Only 

 fifteen sorts are reported on, as in one plot one variety had an advantage over the 

 others and it was not included. The soil on the whole was a uniform, rich sandy loam. 

 The potatoes were kept thoroughly cultivated until the vines met and were sprayed 

 five times, namely, on July 2, 13, 25, August 2, 27. The plots sprayed with the Bor- 

 deaux-Bug Death mixture received an extra spraying on June 22 with Bug Death 

 dry alone. There were no rotten potatoes in the plot sprayed with the Bordeaux- 

 Bug Death mixture. The potatoes were planted on May 28, and dug on October 6.
