DISEASES OF PLANTS.
The control of experimental conditions in phytopathological research, A. A.
POTTER (Phytopathology, 6 (1916), No. 1, pp. 81-88).-The author calls attention
to the necessity for the improvement of methods of phytopathological research in
order that experiments may be more definitely controlled.
Effect of meteorological conditions on development of plant diseases, II,
G. N. DOROGIN (Mat. Mikol. i Fitopatol. Ross., 1 (1915), No. 4, pp. 3-5, fig. 1).This
is the second report (E. S. R., 34, p. 840) on the meteorological conditions
in the region of Petrograd in connection with plant diseases. It covers the
spring months of 1915.
Report of the assistant plant pathologist, 0. D. SHERBAKOFF (Florida Sta.
Rpt. 1915, pp. XCIV-XCVIII).-A brief report is given of investigations begun
by the author, the principal ones being in connection with seed bed diseases of
celery and tomatoes. While a number of diseases of these truck crops are destructive
in parts of Florida, the work has been carried on chiefly with damping
off. This, the author thinks, is due to several organisms, among them a Rhizoctonia,
a Fusarium, a species of Gloeosporium, and Sclerotinia libertiana. Brief
notes are given on the prevailing fungus diseases of a number of vegetables.
These include lettuce drop, early blight of celery, Phomopsis of eggplants,
Cercospora spots of peppers, cucumber rust, and tomato rust.
Notes on parasitic fungi in Wisconsin, I, II, III, J. J. DAVIS (Trans. Wis.
Acad. Sci., Arts, and Letters, 18 (1915), pt. 1, pp. 78-109, 251-271) .-The three
parts of this contribution are supplemental to a provisional list and give somewhat
detailed discussion of a large number of forms. Some of these species
are claimed to be new, while others are provisionally so considered. Several
species not previously reported for Wisconsin are listed, also additional hosts
of these fungi. Alphabetical indexes of hosts are also given.
On fungus parasites of cultivated plants, V. KAZANOVSK'I (Khozfaistvo,
1915, p. 696; abs. in Mat. Mikol. i Fitopatol. Ross., 1 (1915), No. 4, p. 124).-It
is stated that many Russian varieties of wheat and a minority of introduced
ones are attacked by yellow rust.
A survey of plant parasites in 1913 in the Province of Tula, N. P. TRuSOVA
(Mat. Mikol. i Fitopatol. Ross., 1 (1915), No. 4, pp. 35-56).-During the wet
summer of 1913 in the Province of Tula, Russia, the author observed 152 different
diseases on cultivated, and 102 on wild, plants. These include many wellknown
fungus enemies of field and forage crops and of garden, orchard, and
forest plants. Several new species are also described.
New species of mycoflora in the Province of Astrakhan, found in 1914,
S. SHEMBEL (SZEMBEL) (Mat. Mikol. i Fitopatol. Ross., 1 (1915), No. 4, pp.
107-112, figs. 10).-The author gives descriptions of four species which are considered
as new and named respectively Didymosphceria (Didymella) alhaginis
on Alhagi camelorum, supposedly the winter stage of Septoria alhaginis, previously
reported by the author (E. S. R., 34, p. 842); Rhabdospora dodartic and
Hendersonia dodartice on Dodartia orientalis; and Cercospora zygoptfyl on
ZygopVfylmn fabago.
A Gymnosporangium with repeating spores, J. C. ARTHUR (Amer. Jour.
Bot., S (1916), No. 1, pp. 40-45, fig. 1).-Evidence is presented and discussed
regarding the supposed identity of Uredo nootkatensis and A3cidium sorbi, the
name proposed for the new combination being G. nootkatensis.
The physiological relation of the powdery mildews to their hosts, G. M.
REED (Missouri Sta. Bul. 141 (1916), p. 25).-A brief summary is given of investigations
of powdery mildews in relation to their hosts, 22 varieties of wheat
having been tested, all but 3 of which gave 100 per cent infection. Two varieties
