SPRAYING e;XPI!;R1M£NTS AND APPLE DiSlvASHS. 9 



EJFFE^CT OF DlFlfE;RE:NT SPRAYS ON THEJ FRUIT. 



Detailed records were kept throughout the season of the ap- 

 pearance of the fruit with reference to scab and russeting but 

 they tell little which is not also given in the tabulated results 

 of the condition of the fruit at harvest time. The first record 

 of the beginning of russeting of the fruit was on July 7 but the 

 experiment was not visited by the writer between June 24 and 

 this date. It is interesting to note that at this time russeting 

 was recorded on all of the plots, including the unsprayed check. 



The crop was harvested on October 5 and sorted immediately 

 thereafter. In 1912 about 20 barrels of apples from the rows 

 near the center of each plot were set aside for careful sorting 

 and record as to the condition of the fruit. In 19 13, on account 

 of the short and irregular crop on the trees, all of the apples 

 on each plot were saved for sorting and counting except those 

 borne on the half of each outside row which adjoined another 

 plot having a different treatment. While this may not have 

 entirely eliminated the effects of the spray drifting from one 

 plot to another it was felt that it did so in a large measure. 



The following is a tabulated summary of the results obtained 

 from sorting and counting the number O'f fruits on each of the 

 different plots. The percentages of smooth, scabby and rus- 

 seted fruit do not always total 100 for in some instances apples 

 were found which were both scabby and russeted and were 

 cQunted twice. All apples which showed any traces of scab 

 were classed as scabby. None were classed as russeted unless 

 this was plainly evident. That is, apples which showed minor 

 scars or imperfections of the skin were classed as smooth.
