438 Report or THE HorTICULTURIST OF THE 
potassium sulphide for two gallons of water. This treatment is 
repeated at intervals of from seven to ten days depending on the 
amount of rain that comes to wash off the applications. After the 
fruit is marketed spraying is no longer resorted to, although the 
mildew may continue through the season on the ends of growing 
shoots. 
SUN SCALD. 
The ripening fruit of the gooseberry is liable to sun scald. The 
skin at first has a bleached appearance and afterwards the fruit 
shrivels and drops. The conditions which bring about this trouble 
are not well understood. It sometimes causes serious loss. 
Remedy.— The only remedy known at present is to pick the 
fruit while it is green, 7. e., unripe. 
GOOSEBERRY INSECTS. 
The saw flies which attack the gooseberry are of the same species 
at those which are found on.the currant. See page 426. 
GRAPE DISEASES. 
The various prominent vineyard diseases of the State, with the 
exception of the anthracnose, may be controlled by spraying ac- 
cording to directions given for treating the black rot, page 430. 
ANTHRACNOSE. 
(Sphaceloma ampelinum DeBy.) 
Description.— This disease attacks any tender portions of the 
growing vine. When the leaves are affected dark spots are first 
formed on their surface. As the disease advances these spots en- 
large, and irregular cracks are often formed through the dead 
tissue. Frequently many of these small cracks run together, form- 
ing a long irregular slit through the leaf. Similar marks are 
formed on the tender shoots, though they are not so noticeable. 
When the fruit is attacked the disease is sometimes called bird’s- 
eye rot. Circular spots are formed on the surface of the berry.
