ground under the check trees but practically none under dusted trees. The 

 first fruit was picked from these trees on September 9 and Mr. Hawley re- 

 ported on September 21 that there was still some fruit on the dusted trees 

 but none on the check trees. There was little evidence of rot on the Gold 

 Drops previous to harvest on either the dusted or check trees. 



Control of brown rot after harvest. The fruit for "holding" tests was 

 picked on September 9. . The sample for each plot was taken from several 

 trees so as to represent an average condition. No peaches from the check 

 trees were used which showed any rot when picked. The results of the 

 "holding" tests are given in table 14.
