DESCRIPTION OF PLATES. 



Plate I. Frontispiece. Peaches affected with brown-rot, showing the destructive 

 work of the disease, the rotten, moldy appearance of affected peaches, and the 

 gray tufts of spores produced by the fungus. This is a photograph of a pile of 

 discarded Carman peaches in an orchard at Fort Valley, Ga. 



Plate II. Two crates of Elberta peaches picked from the experimental plats at Fort 

 Valley, Ga., on July 9, 1909, shipped by refrigerator car to New York, and then 

 by express to Washington, D. G, opened and photographed on July 16, a week 

 after picking, showing the difference in the amouutof brown-rot developed. The 

 fruit on the left was from a sprayed plat, No. 6, and developed very little brown- 

 rot, while that on the right was from an adjacent unsprayed plat and became 

 badly affected with brown-rot in transit. 



Plate III. Peach scab. Fig. 1. — Two unsprayed Elberta peaches affected with 

 scab, showing the black spots and cracks produced by the fungus. Fig. 2. — The 

 crop of peaches from an unsprayed Elberta tree, showing the fruit badly affected 

 with scab. All the fruit was affected and 86 per cent of it was so "smutty " and 

 cracked as to be unfit for the market. This fruit was from one of the unsprayed 

 trees in the orchard of the Sleepy Creek Orchard Company, at Sleepy Creek, 

 W. Va. 



Plate IV. Peach scab. Fig. 1. — The crop of peaches from an Elberta tree sprayed 

 once with self-boiled lime-sulphur. The good, merchantable fruit (98 per cent 

 of the crop) is shown in the pile and the unmerchantable, scabby fruit on the 

 notebook at the top. This fruit was grown in the same orchard as that shown in 

 Plate III, figure 2. Fig. 2. — The same unsprayed crop shown in Plate III, figure 2, 

 sorted for the market. The large pile of fruit on the right is unmerchantable on 

 account of scab, that on the left representing all that was suitable or packing 

 (only 14 per cent of the crop).
