Worden. This variety is thought by many to be superior to the 

 Concord. It is so nearly like that variety in growth of vine, form, 

 size and quality of fruit that only by close inspection can the differ- 

 ence be delected. It is certainly earlier and that for New England 

 is very decidedly in its favor. Some growers report it more subject 

 to cracking after rain storms. 



MILDEVr AND BLACK ROT. 



Again we are able to report very decided success in the use of 

 copper solution in preventing mildew and black rot, and we feel sure 

 that even those varieties most subject to the attack of these diseases 

 can be made to grow in perfect health. For the best results we 

 would recommend the following treatment: 



1st. Spray the vines and trelHses and the ground under them 

 with the solution of copper sulphate, Formula a, before the leaves 

 unfold. 



2d. As soon as the leaves are well expanded spray with the Bor- 

 deaux mixture one-half strength, i. e. 50 gallons of water to the 

 regular formula. 



3d. Just before the blossoms open, spray again with the Bor- 

 deaux mixture, adding I lb. of Paris green to 100 gallons of the 

 mixture. 



4th. Soon after the fruit has set, spray again with the Bordeaux 

 mixture, and repeat at intervals of from two to four weeks accord- 

 ing to the weather, up to about August ist. Should the weather be 

 dry and cool the longer interval will be sufficient, but if hot, moist or 

 rainy, application should be made not less than once in two weeks. 

 After a heavy rain it is best to make an application at once, if it is 

 near the time for spraying. 



5th. After August 1st, one or two applications of the ammoni- 

 acal carbonate of copper should be made at intervals of from 2 to 4 

 weeks, as further use of the Bordeaux mixture would disBgure the 

 fruit. 



PEACH. 



The peach orchards connected with this station, and many others 

 in the State, did not blossom as full as in 1891, but a fair crop of 

 fruit was set. Generally, throughout the State, the crop was of 

 greatly inferior quality, owing to the effect of drought and cold 

 weather at the time of ripening. 



The trees experimented with were sprayed before the leaves
