10 HATCH EXPERIMENT STATION [Jan. 



The raspberry cane blight, recently described by Prof. 

 F. C. Stewart, 1 has been noted in this State, and specimens 

 have been sent to Professor StcAvart, avIio has reported upon 

 them. How common this disease is, or is likely to become, 

 we are at present not able to say. There has been, more- 

 over, an unusual amount of winter-killing of raspberry canes, 

 resultinsr from the unusual conditions of the fall of 1902. 



Some complaint has been made in regard to a potato stem 

 rot, a disease which is apparently more common in Vermont, 

 where it, with other potato diseases, is receiving serious 

 attention by Prof. L. R. Jones. 



An unusual leaf s})()t disease for this region Avas noted on 

 corn. This Avas caused by the fungus llehnlntJiosporium 

 incons2)icnum C. and E., which gave the leaves a badly 

 spotted ai)pearance, and in one instance rendered the crop 

 practically useless. Probably the extremely abnormal corn 

 weather during the past sunmier was responsible for this. 



A fungus known as Vermicular ia trkJielJa Fr, caused con- 

 siderable spotting and damage to the leaves of the English 

 ivy {Hedera helix, L.). There has been a minimum num- 

 ber of the usual shade tree fungous blights, although the 

 blight of the horse-chestnut leaves, caused by the fungus 

 PliylloMicfa spJuvropsoidea Ell. and Ev., was troublesome, 

 and a considerable amount of defoliation occurred to ma})les 

 from sun scorch. The Norway maple leaves were also 

 greatly lacerated by the winds at the time of unfolding, and 

 they were literally covered with honey dew, which in some 

 cases resulted in the development of a black mold on them. 



The stem rot diseases of the carnation, aster, campanula, 

 etc., have been rather common on out-of-door plants. The 

 usual blights of the melon and cucumber were present, but 

 these crops did so poorly that the fungus had little mate- 

 rial to work on. The general consensus of opinion among 

 growers of melons and cucumbers is that spraying does 

 little or no good when the anthracnose and alternaria are 

 present. This is especially true of the melon, where all 

 attempts at spraying, even when fre(|uently attended to, 

 failed to hold these fungi in check.
