At Nemaha (table 23), no check was left. Therefore, the 
data are of little value except as a comparison of the value of 
Bordeaux and lime sulphur, and to show the value of a late 
spray. The results here indicate that there is practically no 
difference between the effectiveness of Bordeaux and lime sul- 
phur as a fungicide for scab. They also show that no benefit 
was derived from the spray following the second-brood codling 
moth application. However, the summer had been so dry that 
little effect could be expected. Bordeaux caused more injury 
at the second-brood application than did lime sulphur and con- 
siderably more at the later application. This later apphcation 
was followed immediately by rainy weather, which may account 
for the Bordeaux injury. This orchard was neither cultivated 
nor sprayed before this season.
