ing the first half of July. For preventing fungous troubles in 

 this state where only two sprayings can be given, the one 

 made just after the petals fall and the one about two or three 

 weeks later are the most important. If scab is bad, the spray- 

 ing on the unfolding leaves is desirable, and for sooty blotch, 

 the last spraying, in July.' The winter treatment, so far as 

 fungi are concerned, is of the least value. 



In our work this year we used at least three different 

 sprays in each orchard. In every case Bordeaux was used for 

 comparison with the other fungicides, as well as with the 

 unsprayed or check trees. Altogether over 350 trees were 

 sprayed and at least 75 reserved as checks. While these 

 trees were chiefly Baldwins, Greenings and Russets, there 

 were also included a few trees of other varieties, such as 

 Pound Sweets, Gravenstein, Hurlbut, etc. 



The data were taken at harvest time, when the apples 

 were picked from the trees. If the trees bore a small crop, 

 all of the apples were included in the count, but if a large 

 crop, only 500 to 1,000 apples were examined from different 

 parts of each tree. Altogether 60,000 apples were examined. 

 and records kept as to whether they were perfect, or russeted, 

 or showed such troubles as Baldwin Spot, fruit speck, rot, 

 scab, rust, sooty blotch, or injury such as curculio, lesser apple 

 worm, or other insect injury. The percentage of each of these 

 troubles for each tree and for each treatment was then 

 worked out, and tables made for each orchard. This required 

 considerable work, but because of lack of space only the gen- 

 eral tables have been published by the Station in the bulletin 

 just issued. 



In considering the results of the spraying, I shall speak 

 first of the injury caused, as one of the chief objects of the 

 experiments was to obtain light on this subject. The injury 

 to the foliage will be discussed first. More injury resulted 

 last year from spraying than the preceding year, and both 

 were perhaps somewhat unusual years because of the wet 

 springs. Xot only was there considerable injury in our own
