Bramlage and Thompson (26) found that multiple boron sprays increased 
the incidence of water core in Jonathan apples. 
Porritt, McMechan and Williams (133A) describe a flotation method for 
segregation of water core apples, Satisfactory separation in Delicious apples 
could be obtained with solutions of ethyl, methyl, and isopropyl alcohol ad- 
justed to a specific gravity of about 0.877. 
Probably, the best known procedure for dealing with water core is to 
watch for its development in the orchard during harvesttime, particularly in 
fruits well exposed on the southwest sides of trees (146). The fruits should 
be picked before extensive water core develops.
