Table 5. — Effect of handling treatments on incidence of bine mold decay in composite 

 50-apple samples from each of 5 orchards 



[Fruit harvested Oct. 2, 1939, or Sept. 25, 1940, and washed in sodium silicate (80 pounds to 100 gallons) and 

 then in 1.5-percent hydrochloric acid. All fruit, except as indicated, dipped in suspension of blue mold 

 spores, packed in oiled wrappers, and stored at 32°. All temperatures in ° F.]
