Cherries. Witches brooms, Exoascus cerasi Sadeb., were 
reported from St. Petersburg, Plock and Tambov governments, 
which are widely separated from one another. Gnomonici ery- 
throstroma Fuck, causing a leaf spot occurred in Kharkov gov¬ 
ernment and in Caucasus while a leaf and fruit spot due to Clas - 
terosporium amygdalearum Sacc. occurred in Caucasus, in Crimea, 
and in Kursk government. A third leaf spot, Cercosporella 
cerasella Sacc. occurred in the two last named localities only. 
Monilia cinerea Bon. caused serious injury to cherries in parts of 
Kursk government, in many places in Transcaucasus, and at 
Balaclava in Crimea. 
Peach. Leaf curl, Exoascus deformans Fuck., was found 
in 1903 in Kherson government and Crimea, both on the Black 
Sea, especially on Arabian varieties, in Transcaucasus and in 
Transcaspian Province, Turkestan, where it practically defoliated 
the trees in May. Other leaf troubles were Clasterosporium 
amygdalearum Sacc., in much the same localities as the pre¬ 
ceding, except Turkestan, and Puccinia pruni-spinosae Fuck, 
observed near Batum in Caucasus. Considerable injury was 
occasioned to the fruits in many localities in Transcaucasus by 
Glocospormm laeticolor Berk. Peach yellows was reported from 
Sotchi in Caucasus. 
Apricot. Phoma armeniaca Thiim. was so destructive to 
the fruits of the apricot in Transcaucasus that they were very 
rare in the markets. 
Almond. Clasterosporium amygdalearum Sacc., leaf spot, 
and Gloeosporium amygdalinum Brizi, anthracnoses of fruit, twigs 
and leaves, were respectively in Transcaucasus and near Crimea. 
V. BERRIES. 
Gooseberry. Mildew, Sphaerotheca mors-uvae B. & C., was 
first observed in Russia in 1901; by 1902 it had spread to six 
governments, and in 1903 it was reported from nearly all parts 
of Russia and from Tomsk in Siberia; Transcaucasus remained 
as yet unaffected. In contrast with this very destructive parasite 
is Microsphaera grossulariac Lev., which is well known in 
Europe, but causes little damage. It occurred near Riga and in 
Smolensk and Kursk governments. Septoria grossulariae West, 
was quite abundant in Western and Central Russia. Rust, Puc¬ 
cinia pringsheimiana Kleb., occurred abundantly in Novgorod 
and Vladimir governments, and also in Smolensk government 
where it attacked and destroyed more than half the fruits. Al¬ 
though abundant the three previous years on the leaves, the 
fruits were not attacked until 1903. 
Black currant. Cronartium ribicola Dietr. was met with 
in 1903 in several widely separated places, e. g., Lifland in North¬ 
eastern Russia, Lodz in Poland, Kursk government in South Cen-
