In order to determine what effect the respective treatments might 
have on the proportion of fruit which dropped and that which 
remained on the trees until picking time the following table (Table V) 
was prepared from the data in the previous tables:

As will be noted, the highest percentage of drop-fruit was on the 
unsprayed plat, namely, 82.96, with 47.42 per cent drop-fruit from 
Plat III. Plats I and IV (the one-spray and demonstration treat- 
ments) show a difference in favor of the demonstration plat of only 
0.62 per cent, an amount practically negligible. The percentage of 
drop-fruit, including fallen fruit from all causes, is shown, but it 
should be remembered that fruit from all plats, except the check, 
was largely protected from fungous troubles by applications of 
Bordeaux mixture.
