102 PEACH LEAF CURL: ITS NATURE AND TREATMENT. 



By contrasting only the well-developed and spur fruit buds it is 

 learned that there was 14 per cent in the number of buds in favor of 

 the lower limbs on the sprayed trees and 4 per cent in favor of the 

 upper limbs on the unsprayed trees. This showed a difference of 18 

 per cent in favor of the lower limbs of the sprayed trees. The entire 

 comparison is given in the table which follows:
