Prof. Blair : In the case of the King apples we had very 

 severe injury to the fohage in one of our orchards in 191 3, which 

 \vas noticeable throughout the whole season. In another orchard 

 at Bridgetown the injury was not nearly so apparent ; in fact, 

 the foliage during the first part of the season on the trees that 

 were sprayed with Bordeaux was much healthier looking than 

 that on the trees sprayed with lime-sulphur, but this condition 

 reversed before the end of the season, and the lime-sulphur 

 foliage was better on the trees than where Bordeaux had been 

 used. This year we took particular notes as to the foliage con- 

 ditions and we could not notice any particular difference between 

 the lime-sulphur and the Bordeaux foliage. Consequently we 

 concluded that the climatic conditions that followed the applica- 

 tion of Bordeaux, and the condition of the tree and the health of 

 the tree, are all factors as to the amount of injury that may 

 result from the use of Bordeaux. 



BORDEAUX BEFORE BLOSSOMS OPEN VS. LIME-SULPHUR. 



These tests were conducted on a block of Gravensteins at 

 Berwick and were for the purpose of finding out whether Bor- 

 deaux applications before the blossoms opened would control 

 scab equally as well as lime-sulphur. All the applications after 

 the petals fell were lime-sulphur 1.008 and applied at the same 

 date. The sprays before the blossoms opened were on the same 

 date.

THE VALUE OF THE DORMANT SPRAY FOR CONTROL OF APPLE SCAB. 



Experiments were carried out in each of the experimenta) 

 orchards to determine the value of the dormant spray, in addi- 

 tion to the usual sprays for the control of scab. The only 

 difference in application in these plots is that in Berwick a spray
