106 Maine Agricultural Experiment Station. 1918. 



The appearance of the foliage on this plot did not differ 

 materially from that recorded for conditions on plot i. 

 Plot 9. Unsprayed check. 



Scab began to appear on the leaves on the unsprayed check 

 before the third spray application and developed rapidly dur- 

 ing the first part of July. By the middle of the month there 

 was a large amount on the leaves and it was very common on 

 the fruit. A certain amount of fungous leaf-spot also ap- 

 peared. Russeting of the fruit, apparently resulting from 

 weather conditions, was evident early in the season. It was 

 noted that this russeted condition was confined to the upper 

 sides of the fruits as they hung on the trees. 



The Effect of the Different Sprays on the Fruit in 1916. 



The fruit was harvested and sorted the first week of Octo- 

 ber. From the experimental plots in orchard No. 2 only the 

 crop from the two central rows or 12 trees was saved for sort- 

 ing. This was limited to a random sample of 20 barrels where 

 the total crop of these central rows exceeded this amount. The 

 following, Table I, gives the results obtained. The record for 

 orchard No. 1, where plots 1 and 5 were repeated on a large 

 scale was obtained by selecting a random sample of 20 barrels 

 from each half in such a manner that it would represent as 

 nearly as possible the average conditions throughout each part 

 treated in a different manner. These results are given in Table 

 II.
