BLACK ROT. 
The presence of this disease was noted in all the counties visited, but 
its attacks this season have evidently been slight as compared with its 
ravages farther south, only an occasional cluster being attacked. That 
the malady has gained a foothold throughout this section can not be 
doubted, but timely applications of the copper mixtures will, if early un¬ 
dertaken, prevent severe ravages in future seasons. 
ANTIIRACNOSE. 
Found sparingly at Fair Haven, Lyons, and Komulus, where it had 
damaged the fruit principally, only an occasional cane being affected. 
DOWNY MILDEW. 
This disease appears to be one of the worst pests of the New York 
vineyardist, presenting itself in the form of gray rot or brown rot in 
most of the vineyards visited, but as far as seen doing only slight dam¬ 
age to the foliage. 
POWDERY MILDEW. 
Numerous cases of this fungus were seen in almost every vineyard 
examined, except those sprayed with some of the copper mixtures. The 
fruit where attacked becomes discolored, and accumulations of dust 
which can not be removed occur upon the diseased portions rendering 
the clusters unfit for market. 
GRAPE GLGEOSPORIUM. 
This disease,* to be described in another number, although a new one, 
should be carefully looked after. It was noted in every packing house 
visited, and although any of the copper remedies would doubtless check 
its ravages it is likely to prove a troublesome pest. 
GRAPE CLADOSPORIUM. 
Upon two vines of Clintou in Cayuga County the immature stage of 
a species of Gladosjporium was noticed in connection w 7 ith powdery mil¬ 
dew. The berries attacked assumed a dirty orange-yellow hue, became 
rough and unsightly, and were ruined for market purposes. It is hoped 
that the mature spores of this fungus may be found and the species 
identified, but as yet only the mycelial form has been seen forming 
a thick felt composed of much torulosed mycelium upon the epidermis 
of the berry.
