Series 3, Mackintosh, checks (Unsprayed) 



Series 3, Winesap, checks (Unsprayed) 



Series 3 is interesting largely because it shows the results 

 which may be expected on small trees producing comparatively 

 few apples. It also illustrates a marked difference in the liability 

 of different varieties to injury by this pest. 



The six Mackintosh trees in plot 1 produced a total of only 

 272 apples, the average percentage of sound fruit being 88.23, in- 

 dividual fruiting trees ranging from 66.66 to 92.30, though the 

 maximum and minimum number of wormy apples were only I 

 and 13. 



Plot 2. The six Mackintosh trees produced 638 apples, giving 

 an average percentage of 95.76 of sound fruit. There were only 

 27 wormy apples in the plot, the number per tree ranging from 

 nothing to 12, yet the percentage variations ran from 81.25 

 to 100. 



The six Wealthy trees in plot 1 produced 1430 apples, giving 

 an average of 96.08 per cent of sound fruit. There were 56 

 wormy apples, individual trees producing from 4 to 12 and giving 

 a percentage variation from 87.72 to 98.
