grape juice; and the remaining 5 per cent, into wine. In California 15 

 per cent, are grown for table use, 30 per cent, for raisins, and 55 per cent, 

 for wine. A good vineyard will produce on the average about 1,000 eight- 

 pound baskets per year, although there are exceptional vineyards, receiv- 

 ing good care and on good soil, which have produced double that amount. 



As to the enemies of the grape, the root-worm beetle is the worst in the 

 Chautauqua region. In the larva stage it feeds on the fine roots and 

 causes very serious damage to the vines. In June or July the beetle comes 

 out of the ground and feeds on the leaves. Spraying at this time with 

 lead arsenate serves somewhat to keep the insect in check. 



In the Central Lake and in the Hudson Valley districts, mildew and 

 black rot are very serious diseases. The mildew attacks the leaves and to 

 some extent the fruit, using up the vitality of the vine. Spraying about 

 twice, two weeks apart, with Bordeaux mixture soon after the leaves are 

 well out in the spring will control this disease. The black rot attacks the 

 fruit, causing it to decay on the vines, the worst infection usually occur- 

 ring in July, especially with wet weather. Treatment for this should be 

 by spraying every week or two with Bordeaux mixture, about a day or 

 two before a rain if possible, as the spores begin to germinate soon after 

 a wet day, and the poison mixture if dried on the vine will prevent the 

 growth of the spores. There are a few minor diseases and enemies here 

 in the east, but the ones mentioned are the most important from the 

 grower's point of view.
