216 Report OF THE BoOTANIST OF THE 
It seems probable that the disease of red raspberries is the same 
of that of the black varieties. It may, perhaps, be aggravated 
by drought, but the evidence in hand is opposed to the theory that 
drought is the sole, or even the principal, cause. In the first 
place the symptoms are not those of drought. On raspberry canes 
suffering from drought the foliage becomes yellowish, the berries 
are abnormally small and the whole plant gradually dries up. All 
of the fruiting canes in a hill are about equally affected; in fact 
the whole plantation, if on. fairly uniform soil, will be uniformly 
affected. Whereas, in the disease under discussion, canes die 
here and there with diseased canes and healthy canes occurring 
even in the small hill. 
We are not prepared to say positively that the Phoma found on 
the affected canes is the cause of the disease because no inocula- 
tions with it have been made; but it is certainly to be regarded 
with suspicion. This disease is a worthy subject of investiga- 
tion.*° 
LEAF SPOT. 
(Septoria rubt Westd.) 
Rare. Observed only at Poughkeepsie. 
STRAWBERRY DISEASES. 
DROUGHT. 
Strawberries were damaged more by drought than by all di- 
seases combined. The few persons so situated that they could 
irrigate their strawberries reaped a harvest of profit. 
LEAF BLIGHT OR LEAF SPOT. 
(Sphaerella fragariae (Tul.) Sacc.) 
The situation with regard to this disease may be summed up in a 
phrase used by several of our correspondents; namely: “ Severe 
on some varieties.” It has not been nearly so virulent as in 
33 The supposedly bacterial disease of Turner and Marlboro rasperries de- 
scribed by Freda Detmers, in Ohio Agr. Exp. Sta. Bul. 6, p. 128, seems to be 
different. |
