Spraying Experiments in Nebraska

Bordeaux proved to be higher in efficiency than lime sulphur 
but the 14-days application did considerable damage by russeting 
the fruit. The 21-days application did more damage than the 
35-days spray. Plat 6 showed almost as much infection as the 
check plat. Here, however, only the variety Missouri Pippin 
was considered. This variety is much more susceptible to blotch 
than the Ben Davis.

The evidence shown in table 38 corroborates that shown in 
table 37. In addition it indicates that a lime sulphur apphcation 
on August 10 was of no value for control of blotch. Here it will 
be noticed that in contrast to table 37 lime sulphur for the 14-days 
spray was 61.5 per cent efficient. In fact, the efficiency of the
