ther west, rot, mildew, early frosts, and rose bugs. The 

 destruction by insects and mildews is largely the result of 

 poor cultivation and lack of care. 



The following, condensed from Bulletin XIX., August, 

 1890, of the Cornell University Agricultural Experiment 

 Station, Ithaca, N. Y., may be of interest and value to 

 grape growers in this State : — 



' ' We warn our readers not to put faith in statements that 

 certain varieties of grapes are exempt from diseases, for 

 some of the most serious cases which we have seen this 

 year were noticed upon a variety which has been said to be 

 free from attack. The advent of rots and mildews is not a 

 cause for alarm. They are to be expected, and they will 

 undoubtedly spread. But the means are at hand to keep 

 them in check easily and economically. The mildews and 

 rots can be kept in check by the timely and persistent use 

 of Bordeaux mixture. Begin before the flowers open, and 

 spray every week or ten days until well into August. For 

 anthracnose (the fungus which causes the scab of the berry 

 and on the wood causes black, shallow pits), sulphate of 

 iron applied before the leaves appear is probably the best 

 remedy. After treatment should be made with Bordeaux 

 mixture." 



Experiments have shown that girdling the grape vine 

 makes a decided gain in the time of ripening of the fruit ; 

 that there is no loss of sugar, and that the increased size of 

 the fruit makes it very attractive, and more than makes up 

 for any increased softness of the berry.
