24 SPRAYING PEACHES, 
It will be seen from Table IV that the brown-rot was thoroughly 
controlled, even where 70 per cent of the unsprayed fruit rotted, as 
was the case with the Elberta. The scab was also held down so that 
it was commercially negligible. The Summerour is particularly sus- 
ceptible to scab, and has been unprofitable in Mr. Kitchen’s orchard 
on account of this disease. On the unsprayed trees 72.5 per cent of 
the fruit was badly affected with scab, while less than 1 per cent of 
the sprayed fruit was badly affected. By referring to the column 
showing the percentage of merchantable fruit in Table IV it will be 
seen that from 82.6 to 97.7 per cent of the sprayed fruit was mer- 
chantable and from 7.5 to 51.5 per cent of the unsprayed fruit was 
merchantable. The difference between these two sets of figures rep- 
resents the difference between success and failure. 
In Table V are shown the results from 12 sprayed and 12 unsprayed 
Elberta trees in the same orchard and given the same treatment as 
those considered in Table IV, but located in a different section of the 
orchard. The fruit was picked from July 26 to August 1 and sorted with 
reference to brown-rot, scab, and curculio. To determine the presence 
or absence of the curculio all the fruit was sliced into several pieces.

It will be seen from Table V that 0.9 per cent of the sprayed fruit 
was affected with brown-rot, 39.26 per cent with scab (practically 
none of which was bad), and 13.15 per cent with curculio, while 18.04 
per cent of the unsprayed fruit was affected with brown-rot, 100 per 
cent with scab, and 51.19 per cent with curculio. It is iso shown 
that 97.61 per cent of the sprayed fruit was merchantable, as against 
46.49 per cent of the unsprayed fruit. Had all the fruit infested with 
curculio been thrown out the percentage of merchantable fruit from 
both the sprayed and the unsprayed trees would not have been quite 
so high. Much of the infestation consisted of young worms just 
hatched, and in such cases the market value of the fruit had not been 
materially affected. In addition to these 12 trees the crop from a 
block of 70 sprayed and 70 unsprayed Elberta trees was sorted and 
packed for the market. It was found that 97.04 per cent of the fruit 
of the sprayed block was merchantable, leaving 2.96 per cent as culls. 
From the unsprayed block only 54.11 per cent of the crop was mer- 
chantable and 45.89 per cent unmerchantable, a gain of 42.93 per cent. 
A block of 1,000 Summerour trees, which is a late-maturing vari- 
ety, ripening at Baldwin last season, August 27 to 31, was given 
440
