Drupaceous Fruits 95 



of the rosette are still green and delicate. The compact 

 bunching of the leaves is very conspicuous, and makes the 

 trees look quite unlike those affected by yellows. Where a 

 tree is attacked in all parts, it matures no fruit. In all the 

 cases which have been noticed the fruit borne by affected 

 trees either shrivels while green and drops off, or else ripens 

 naturally. 



"In the absence of premature, red-spotted fruit, in the 

 severity of the disease from the outset, and in its rapid 

 progress, it is quite unlike yellows, which is decidedly chronic, 

 and the first slight symptoms of which usually occur in very 

 green and thrifty trees, and are frequently overlooked the 

 first season." 



The treatment is to cut and burn infected trees. No care- 

 lessness should be tolerated as regards this disease or yellows. 



Little-peach. ^^^"^^^ — This seems first to have been pub- 

 licly noted by Smith in an address in Michigan in 1898, in 

 which state it had been of alarming character prior to 1893; 

 since these years it has appeared in New York, New Jersey, 

 and Canada. The most prominent symptom is small, un- 

 developed fruit, one-half to one-third the usual diameter, 

 ripening some 10 to 14 days later than normal fruit, and 

 having "stringy" flesh and insipid or bitter flavor. The 

 somewhat drooping leaves are small, one-half normal size, 

 and vary from light green to yellowish-green. An orchard 

 once affected is of no further value, and should be removed 

 and lun-ned because of the danger of contagion. 



Frost Injury. — Peaches are especially susceptible. For 

 discussion, see apple. 



Minor diseases 



Pustular-spot ^"' (Hehninthosporium carpophilum Lev.). — 

 Peaches affected with this disease are described by Selby as 

 "Badly disfigured, having numerous pimply red spots with 

 light brown centers." Upon yellow varieties the pustule is 

 commonly lacking, there being simply a light brown center 

 with a red border. As the fungus which causes this spot rests
