CONTROL OF PEACH DISEASES IN GEORGIA 
17 
No data on curculio control were taken for the fruit from Plat VII, 
as the arsenate-of-lead treatments on this plat w ere the same as those 
on Plat VI. The dust schedule used on Plat VII was used for testing 
the effectiveness of a low percentage of sulphur for control of brown 
rot and scab. 
All applications of liquid and dust made in the season of 1923 were 
applied with large power spraying and dusting machines. This, and 
all other operations in 1923, were performed by the writers. 
Tables 8, 9, and 10 present the results, in percentages, of the experi- 
ments in spraying and dusting conducted on the Hiley variety during

Fig 
-Diagram of orchard of Elberta peaches, used for experiments in the season of 1923. Each 
tree is represented by a circle, the solid black circles representing record trees 
the season of 1923. Table 8 presents the data obtained from cutting 
open the fruit harvested from the record trees of each plat. The 
apparent discrepancies between "sound fruit" and "merchantable 
fruit" in this table were due to the fact that many peaches con- 
taining only a few scab spots were allowed by the graders to pass as 
merchantable fruit. Table 9 contains the percentages of curculio- 
wormy fruit that dropped to the ground from the record trees at 
various times before harvest, and Table 10 presents the commercial 
results, in merchantable and cull fruit, from all the trees in each plat.
