APPLE BLIGHT.* 
Never before have I seen this disease one tenth part as destructive. 
In middle and north Georgia the apple trees were badly spotted by it. 
The injury was not confined to twigs, but affected branches of several 
years’ growth, greatly injuring next year’s fruit prospect. The disease 
was also common in Pennsylvania, where in other years I have found it 
common, although confined principally to the twigs. In Michigan it was 
not seen. In Kansas it was worse even than in Georgia. At Manhattan 
I was show n several young and thrifty orchards of bearing age which 
had been sadly injured. The attack began in 1889 and continued this 
year with increasing severity. The disease was not confined to twigs, 
but often destroyed large limbs and in some cases one-half or even 
the whole of the tree, as in pear blight. The owner was in despair. 
Certain varieties were noticeably worse injured than others. This was 
found to be true for different orchards and both years. Certain sorts 
escaped almost entirely. 
PEAR-LEAF BLIGHT, t 
In Dr. W. S. Maxwell’s orchards the Lawrence aud Bartlett pears in 
sod ground were very slightly attacked. They held their foliage prac¬ 
tically intact until October 15. The cultivated trees were badly affected 
aud shed their foliage early, except Keifer, which did not sufi'er. I ob¬ 
served this fungus at Still Pond, Md., in 1887, in these same orchards 
and elsewhere, and also in other parts of the peninsula, but it was not 
destructive and was not then considered of any consequence by any of 
the pear growers. Now they are all talking about it. 
This year quince and pear orchards all over the Delaware and Chesa¬ 
peake peninsula were seriously defoliated, and, as a consequence, were 
quite commonly in second leafage and blossom in October. The injury 
last year was also very great, amounting in some large orchards to an 
almost total loss of the crop. 
BLACK ROT. £ 
In Georgia and Kansas the summer was hot and dry. Vineyards in 
both States ripened a large and fine crop of fruit, which was almost 
free from rot. Enough Lcestadia could be found for specimens, aud the 
same was true for Peronospora viticola, but neither did auy injury. 
In Delaware there was also a long drouth in midsummer and black 
rot was not seriously destructive. 
VINE BLIGHT.§ 
In good soil in one corner of a fine bearing vineyard near Griffin, Ga., 
twenty-five or thirty thrifty vines suddenly sickened in midsummer and 
* Bacillus amylovorus , (Bunill) Trev. 
t Entomosporium maculatum , L<5\\ 
X Tap, stadia Bidwelli, (Ell.) V. and R. 
§Later this blight was attributed to lightning, by the owner and others, who said 
lightning had also caused a similar appearance in the cotton fields.
