“Black Spot” Disease. 
By H. TRYON, Entomologist and Vege. 
table Pathologist. 
The diseose of the vine known in Aus- 
tralia as Black Spot, and originally 
identified by the writer with the An- 
thracose (H'rench) and Schwarze Brenner 
(German) of European vignerons (vid. 
Tryon, H.—Insect and Fugus Pests, on 
the living tissue of either wood, leaf, 
tendril, flower stalk, or fruit of a minute 
parasitic fungus, technically designated 
Gloeosporium ampelophagum (or Space- 
loma ampeiinum). 
The external features as well as the 
. character of the injuries connected with 
“ Black Spot” or ** Anthracnose” aré too 
well known to need description here, and 
the minute fungus organism that ocva- 
sions it so little patent to observation 
that. further reference to it may be 
omitted after stating that the spores or 
seeds that it sheds, and whose presence 
constitutes the dull reddish grey centres 
of the ‘spots,’ are so small that it would 
require nearly 500 placed on and touching 
one another to covera single inch of ex- 
tent. 
The treatment of this malady is in 
great part a preventative one, and in its © 
details has reference to the following 
facts relating to the dissemination of the 
latter :— 
I. Its first introduction into a district, 
or even into a vineyard, is almost always 
effected through the medium of cuttings 
which, if they do not exhibit the charac- 
acteristic markings that it has occasioned, 
at least may harbor the fungus germs | 
(spores). 
2, Its continuance in a vineyard from 
one season to another 1s dependent upon 
the persistence of the fungus parasite in 
a living condition, on or closely within the 
surface of the ripened wood. ‘ 
Its virulence as a disease is dependent 
upon successive infection of one part after 
another of the growing grape vine as 
spring and summer proceed, its onset 
and progress being favored by humid 
conditions and a variety of grape vine 
especially susceptible to its attack 
Whenceit happens that the disease ex- 
ists permanently in the coastal districts 
of the State, whilst in more western 
localities only occasionally, as a seriously 
injurious malady; and, under both con - 
ditions, certain kinds of grape vine 
escape its attacks.
