Cotton. In 1902 at the experiment station at Tashkent, in 
Turkestan, about sixty per cent, of the cotton was destroyed by 
Neocosmospora vasinfecta E. F. Smith, the native sorts alone 
being attacked, the American sorts remaining immune. In 1903 
the disease did not reappear. A bacterial gummosis of the base 
of the stems proved quite injurious, however, to three varieties 
of native cotton. Anthracnose, C oil cto trie hum gossypii Southw., 
was found in 1902 and 1903 in Caucasus, as was the areolete leaf 
spot, Ramularia areola Atks., for the first time in 1903. 
Sesame. In 1902 a wilt disease of sesame was found at the 
Golodnaya Steppe experiment station in Turkestan. It was 
caused by the fungus Neocosmospora vasinfecta var. sesami Jacz. 
The reviewer collected this at the same place in September of 
that year. In Transcaucasus a species of Ascochyta caused in¬ 
jurious leaf spots. 
Peanut. In various spots in Transcaucasus the peanut suf¬ 
fered with the attacks of two different rusts, viz., Puccinia ara- 
chidis Speg. and Uromyces arachidis P. Henn. 
Ramie. Metasphaeria boehmeriana Sacc. on the stems, and 
Cercospora boehmeriana Peck on the leaves were abundant at 
several points in the Caucasus. 
Tea. The tea plantations at points along the coast of the 
Black Sea in the vicinity of Batum suffered severe injury some 
years from Pestalozzia guepini Desm. In 1903, however, the 
injury was slight. The same disease affected Camellia, Mag¬ 
nolia, Rhododendron, Lemon and Almond. 
Citrus spp. The disease known elsewhere as Mai di Gomma, 
due to Fusarium limoni Br., occasioned serious injury in Cau¬ 
casus near the Black Sea. Sooty mould, Meliola penzizi Sacc. 
was also abundant, also attacking Camellia. 
Olive. As a result of the attacks of Cycloconium oleaginum 
Cast., affecting the foliage, the yield of olives at some points in 
Caucasus along the Black Sea was reduced one-half. In the 
same region sooty mould, Antennaria elaeophila Mont., was 
abundant. The anthracnose due to Gloeosporium olivarum Al¬ 
meida became a serious pest at one point in the same region. 
It had never been destructive in Caucasus before, although very 
destructive in Portugal. 
Fig. The only disease of the fig noted in 1903 was rust, 
Uredo Hci Cast. This was abundant near Batum, but further 
North along the coast was not found. 
Kaki. Up to 1903 the only disease of the Japanese Persim¬ 
mon that had been observed in Caucasus was Cercospora kaki E. 
& E. near Batum. In that year, however, the fruits were attacked 
when half grown, and caused to fall, by Botrytis diospyri Brizi.
