causing them to appear scabby and pitted. (Fig. 9.) The 

 blotches are brownish-black, and at picking time they are usually 



conspicuous. The 

 disease weakens the 

 canes and the ber- 

 ries dry up as if suf- 

 fering from drouth. 

 It also attacks the 

 leaves. It appears 

 to be widely distri- 

 buted in New York. 

 Our own plantations, 

 particularly the Shaf- 

 fer, are becoming 

 badly diseased. In 

 one of the large rasp- 

 berry plantations in 

 Orleans Co., run in 

 connection with an 

 evaporating estab- 

 lishment, the disease 

 occasioned a serious 

 loss. 



In the treatment 

 of this disease it is 

 very important that 

 the plants be kept in 

 a thrifty condition. 

 Our bushes have suf- 

 fered less than others we have seen in market patches which were 

 less severely attacked, simply for the reason that they are robust. 

 It is not necessary to practice laborious culture. We treat our plan- 

 tations cheaply by cultivating them lightly once or twice a week 

 until the berries begin to ripen, and again after the berries are off 

 until well into August. Light and frequent cultivations in loose 

 and well-tilled soil are much less expensive than half the amount 

 of tillage upon neglected or poorly treated soil, and their effect 

 upon the plants is greater. 



There have been no systematic experiments published, so far as 

 I am aware, upon the treatment of raspberry anthracnose with
