]S"otes taken August 2d and 28th, show that the fungicide had been 

 of some value in checking the anthracnose, but the effects were not 

 so marked as was desired. The canes of the unsprayed Shaffer 

 were very much pitted, the older and larger ones being considerably 

 swollen and bent in places. The smaller canes as well as the leaves 

 also showed an abundance of infected places. The portion of the 

 rows which received the two treatments in June were not in much 

 better condition than the untreated plants. 

 The lower portion of the canes were 

 severely attacked, and although the num- 

 ber of pits did not appear to be so abund- 

 ant, still all parts of the plants were more 

 or less affected. The bushes receiving the 

 greatest number of treatments were the 

 most healthy, but the benefits derived 

 from the fungicide were not sufficiently 

 marked upon either variety to encourage 

 a grower to repeat the same line of treat- 

 ment. Some protection was undoubtedly 

 afforded and the plants were plainly in 

 better condition than their untreated 

 neighbors, yet the use of the Bordeaux 

 mixture during the growing season can 

 not be recommended as being of much 

 practical benefit. If the bushes are to be 

 sprayed, the first application should be 

 made as soon as the new canes appear, and 

 these should be kept covered as well as 

 possible. If some more adhesive material 

 than the Bordeaux mixture were employed, 

 better results would probably follow." 



These various results are conflicting. For 

 myself, I do not believe that spraying alone 

 is sufficient to keep down the anthracnose. 

 The very first requisite to clean patches is 

 a short rotation. Remove the plants just 

 as soon as they become weakened, either 

 from anthracnose or age. Next, thin out the young canes and 

 exercise care to remove and burn those which are most diseased. 

 Third, cut out and burn the old canes just as soon as the fruit is 

 off. These three operations are essential to the best raspberry
