DISEASES OF THE BUSH FRUITS 203 



The White Grape and the White Imperial are the most 

 common varieties. 



The black European currants are not grown to any extent 

 in this country. The disagreeable odor of the plant and the 

 peculiar flavor of the fruit are objectionable to many people. 

 This currant has some advantages and a few plants should 

 be grown. The Black Naples is the most widely planted 

 variety. 



The important American varieties of gooseberries are even 

 less in number than the currants. The Downing, the Pearl, 

 and the Houghton are perhaps the most popular of the 

 American sorts. These varieties are thrifty growers, very 

 productive and are comparatively free from disease. They 

 are excellent for cooking and for making jelly, but they 

 are not equal in quality to the English varieties for eating 

 out of the hand. The English varieties have been devel- 

 oped to a much greater degree than the American types. 

 There are over one thousand well-developed English sorts 

 of which some are suited to the American gardens. Of the 

 English types the Columbus, Chataqua, Industry and the 

 Triumph are best suited to the American garden. The 

 English types are usually less vigorous and less productive 

 than the native varieties. 



DISEASES OF THE BUSH FRUITS. 



The diseases and the insects affecting the bush fruits 

 are similar, and many that are found on the one plant are 

 also common on the other. 



Leaf Spot. — The leaf spot is a disease that affects the 

 leaves, and it is found on both the currant and the goose- 

 berry. It is easily recognized because of the large well- 

 defined spots, with pale centers, which are surrounded by 

 a brownish border. Spraying with the standard 4-4-50 

 Bordeaux mixture is effective in controlling this disease. 

 The spraying should begin just as the buds are opening, and 

 repeated at intervals of two weeks until four or five sprays 

 have been given.
