and turn reddish-brown. The whole berry may be thus discolored. 
After a time the affected berry develops little black pimples or 
pustules much like those of the Black Rot, but not so numerous. In 
this case, however, the berry does not turn black, but retains its 
brown color as it dries up. The dried fruit is more likely to drop to 
the ground, and in this respect, the disease differs from the Black 
Rot. 
Remedy. — The application made for the Black Rot will be effectual 
in protecting vines against the Ripe Rot, particularly, if the later 
applications are made. As a rule, Ripe Rot never seriously reduces 
a crop, and, therefore, cannot be regarded in the same class as the 
four previously described diseases. 
WHITE ROT. 
( Coniothyrlum diplodiella. ) 
This is a fungous disease of minor importance, but it may break 
out seriously in certain localities. It has been located in Ohio and 
New Jersey and no doubt it exists iu Pennsylvania. It has been de- 
scribed as being in vineyards of Italy, though it is known to be a 
native of America. 
Symptoms.— This fungus attacks the peduncle of the fruit and de- 
velops there. As a result the berry shrivels up and becomes dry. 
Later, little black pustules or pimples like those of Black Rot may 
be seen on the surface of affected parts. These are not likely to 
occur until the grapes begin to ripen. 
Remedy. — The use of Bordeaux mixture is recommended as the 
best treatment to be given vines affected with the White Rot. Vines 
which have been treated for Black Rot or the mildews are protected 
against the White Rot also. 
OTHER FUNGI ATTACKING GRAPES. 
There are several other fungi that attack the grape, but never 
with serious consequence. The vineyardist who keei;s a close watch 
upon the health of his vines will undoubtedly meet with some of 
them, but unless the evidences he finds correspond closely to the 
symptoms of the diseases already described, he does not need to be 
alarmed for his crop. 
INSECTS. 
The United States Department of Agriculture has records of over 
100 different kinds of insects as feeding upon the grape-vine and yet 
this plant is looked upon as comparatively free from insect enemies. 
It is true that the grape phylloxera has caused the loss of many mil
