EXPERIMENT STATION BULLETINS. 183 



GRAPES. 



Results with gi'apcs have been somewhat unsatisfactory this season. This was 

 due to several causes, among which were injury by winter, several varieties being 

 frozen to the ground and others more or less damaged; attack of both dovvny and 

 powdery mildew, especially the latter, and a hard frost on the night of September 30, 

 which caused the leaves to fall considerably and prevented some of the late ripening 

 varieties from maturing properly. 



Before the buds opened, the vines were sprayed with copper sulphate, one pound to 

 fifteen gallons of water. For the powdery mildew liver of sulphur was used at the 

 rate of three ounces to ten gallons of water. This solution was applied on the first 

 appearance of the disease in early August. Two weeks later, downy mildew appearing 

 also, the plants were again sprayed, copper sulphate being used for this application 

 at the i^te of one pound to two hundred and fifty gallons of water. These attacks 

 of mildew Avere confined jirincipally to hybrids with V. vinifera. The vines were 

 quite free from the work of insects. 



Adirondack was killed nearly to the ground by the freeze. It has not proven of 

 A-ahie here. Biack Eagle was also badly killed back, and bore only a few small clusters 

 of fruit. It is a grape of good quality, but lacks vigor, productiveness and hardiness. 

 Brighton set a fair crop of fruit, but most of it was badly coated with powdery mildew. 



Campbell Early is one of the most promising of the new varieties. Tlie vines are 

 vigorous, hardy and productive. Bunches long, shouldered, moderatelv eomnact : 

 berries large, fiirm, cling to stem well. Ripens with Moore Early, keeps well, and is of 

 goofl quality. 



Delaware and Diamond bore very full crops. Downing and Mills were frozen to 

 the ground. Duchess was quite badly injured and bore but little fruit. Etta yielded 

 a very large crop, but it is too acid tind low in quality to be of much value. It is a 

 white grape, borne in large, compact clusters. 



Goldstein is a new black variety set in ISOT. It j^roves very vigorous, hardy, and 

 productive, but is of poor quality and shells badly. Guinevra and Josselvn 'i >■ re 

 among the more productive varieties. Guinevra is a large white grape of good quality, 

 borne in medium to large compact clusters. Josselvn 9 is a dark purple grape of 

 rather poor quality. The clusters are long, cylindrical, moderately compact. 



Niagara was quite unproductive. The vines were somewhat injured by the winter, 

 but made a strong growth of new wood this season. Pocklin?ton came through the 

 winter uninjured and bore a full crop. Rogers Nos. 24 and 30, and Secretary, were 

 killed to the ground. Triumph, which is a southern grape requiring a long season, 

 has usually failed to mature })roper]y here, but this season ripened fairly well. How- 

 ever, the quality of the grape as grown in this section is poor and the bunches, although 

 very large and compact, were rather unattractive in appearance because of the attack 

 of powdiry mildew. 



Ulster and Woodruff set too much fruit, and this, together with the frost of Sep- 

 tember 30, prevented the ripening of more than a small part of the crop. Ulster is a 

 red grape of good quality, with its berries in cylindrical, compact clusters. Wood- 

 ruflf is also a red grape. The bunches which are sometimes inclined to be small and 

 imperfect were large and compact this season, but the quality was very poor.
