20 CONTROL OF PEACH BROWN-ROT AND SCAB. 



appeared to be about equal in the two blocks, but was very light in 

 both. So far as could be determined, the difference in yield was due 

 entirely to spraying. It appears, therefore, that in the combined 

 self-boiled lime-sulphur and arsenate of lead spray we have an effect- 

 ive remedy for the peach scab, brown-rot, and curculio, the yield 

 from the sprayed trees in this instance being ten times that from the 

 unsprayed trees. 



MARKETING TEST. 



In order to determine the carrying quality and market value of the 

 sprayed as compared with the unsprayed fruit, two cars of peaches 

 from the experiment blocks were shipped to New York, examined on 

 arrival, and sold in the usual way through a commission house. This 

 test was accomplished through the cooperation of Mr. Hale and the 

 Georgia Fruit Growers' Exchange. 



The fruit for the first car was picked on Friday, July 9, in a drizzling 

 rain, but was not loaded and billed out until the following day. It 

 was due on the New York market the following Tuesday morning, 

 but was delayed en route and was not sold until Wednesday morning, 

 July 14. This car contained Elberta peaches from the lime-sulphur- 

 arsenate-of-lead block and from the adjacent check block, Belle 

 peaches sprayed three times with lime-sulphur alone, and unsprayed 

 Belles. The market was almost glutted with poor fruit and the 

 prices were at about the lowest point of the season. The fruit was 

 sold at the following prices: 



Sprayed Elbertas $2. 00 per crate. 



Unsprayed Elbertas 1. 50 per crate. 



Sprayed Belles 1. 25 per crate. 



Unsprayed Belles 1. 12 J per crate. 



The fruit of the second car was picked on Monday, July 12, and 

 was sold on Thursday morning, July 15. This car contained Elbertas 

 sprayed twice and Belles sprayed three times with the self-boiled 

 lime-sulphur; also unsprayed fruit of both varieties. The fruit of 

 this car brought the following prices: 



Sprayed Elbertas $1. 45 per crate. 



Unsprayed Elbertas 1. 25 per crate. 



Sprayed Belles 1. 50 per crate. 



Unsprayed Belles 1.14 per crate. 



In the first car the difference in favor of the sprayed fruit was 50 

 cents a crate for Elbertas and 12| cents a crate for Belles. In the 

 second car it was 20 cents a crate for Elbertas and 36 cents a crate for 

 Belles. An examination of several crates of Elbertas showed that 34 

 per cent of the unsprayed fruit was specked with brown-rot, while 

 only 6 per cent of the sprayed fruit was so affected. (See PI. II.) 

 This difference in market value was due to the fact that the sprayed 

 fruit showed less rot, was more highly colored, and had a better ap-
