RESULTS 



Since the injury caused by the spray itself is one of the most 

 important matters in peach spraying, special attention was given to 

 it throughout the experiment. The extent of the injury as well 

 as its nature was noted. The amounts of twig injury and of fruit 

 and leaf-drop were determined by trial counts and estimates. The 

 injury to the picked fruit was determined by the random-sample 

 method described below. The approximate maximum injuries are 

 shown in Table IT. These injuries were not all at their maximum 

 at the same time, those from the Bordeaux preparations developing 

 most slowly. The fruit drop recorded against the checks approxi- 

 mates that occurring on the unsprayed trees from various causes, 

 up to picking time.
