Plat V, which received the demonstration treatment, gave 94.13 
per cent fruit free from codling-moth injury, as against 84.07 per cent 
fruit free from this insect on the one-spray plat, a difference in favor 
of the demonstration treatment of 10.06 per cent. The check or 
unsprayed plat (VIII) shows 53.02 per cent fruit free from codling- 
moth injury, and there is thus a gain in sound fruit by the demon- 
stration treatment of 41.11 per cent and by the one-spray method 
a gain of 31.05 per cent of sound fruit. As will be seen from the 
foregoing table, there were counted in Plats V, VI, and VIII, respec- 
tively, 14,077, 20,838, and 19,236 apples, a total for all plats of 
54,151. Undoubtedly the results from the one-spray plat are less 
favorable than would have been the case had there been no hail. 
The injured places on the sides of the fruit permitted ready entrance 
of the larve, as indicated on all plats by the relatively high percentage 
of larvee which entered the fruit on the side. This condition is shown 
in Table XI, which gives the places of entrance of the fruit for each 
tree of each plat for the total larve of the two broods throughout 
the season.
