RASPBERRY DISEASES. 
ANTHRACNOSE. 
(Gloeosporium venetum Speg.) 
The replies to our circular letter of inquiry indicate that rasp- 
berry anthracnose has been common. Although not so stated, 
these replies probably relate to anthracnose on last year’s canes. 
Judging from our own observations we believe that canes of the 
present season’s growth have been but slightly affected. 
RUST. 
(Pucca peckiana Howe. Syn. Caeoma ntens Schw.) 
Rust has occurred in several plantations, but not to a destruc- 
tive extent except in a very few cases. Under some conditions 
rust has a tendency to reduce the number of prickles. For a more 
detailed discussion of this subject, see Blackberry Rust, page 194. 
ROOT GALLS. 
We know of but one occurrence of this disease in the Hudson 
Valley. Others probably exist, however. In April a fruit grower 
at, Madalin, Dutchess County, sent us a red raspberry root bear- 
ing several rough, spongy, roundish knots or galls varying from 
the size of a pea to that of a walnut. The sender wrote that in 
the spring of 1898 he had purchased 30 Loudon raspberry plants 
from a Rochester nurseryman. A year later half of them had 
died from the root galls. 
The cause of such root galls is not known. ‘There is some 
evidence that the disease is communicable from one plant to 
another, and also from raspberries to peaches and vice versa. 
Plants showing root galls should not be planted, not even after 
the galls have been removed. 
WINTER INJURY. 
Red raspberries not laid down were injured by the severe win- 
ter. At Poughkeepsie, red raspberries of the variety Marlboro 
winter-killed nearly to the ground, while Miller’s Red in the
