1032. Atkinson, Geo. F. Some leaf-blights of cotton. <Ala, Exp. Sta. Bull. No. 36, 
Auburn, Mar., 1892, pp. 32, pi. 2. 
Describes yellow leaf-blight (the same as black rust of previous papers) as a physiolog¬ 
ical disease, due to imperfect nutrition or assimilation. Gives an account of the appear¬ 
ance of the disease on the leaves, the injury to which may be increased by the growth of 
fungi under favorable conditions. Gives details of experiments with various fertilizers, 
especially with kainit and nitrate of soda. The former tends to prevent the disease and 
also to increase the crop. Gives history of kainit as a preventive, and discusses the effects 
of the characters of soil on the disease. “ Red leaf-blight” is due to hastened maturity of 
the plant, caused by impoverished condition ot the soil, and maybe prevented by use of 
proper fertilizers. “Cerealite” is said to produce good results (see Exp. Sta. Rec.', vol.m, 
July, 1892, pp. 844-845). (J. F. J.)

Notes the spread of disease in the South, as well as its virulent nature, and recommends 
immediate destruction of all infected trees. Wild plums in vicinity should be destroyed, as 
disease appears among these tirst and then spreads to cultivated trees. (J. F. J.)

This seems to be a new disease, which has lately appeared in the French vineyards. The 
leaves become dry and curl up in the form of a tube, and this takes place very suddenly, 
while the petiole shows an annular incision at the base of the blade or where the petiole is 
joined to the stem. The leaves do not drop oft but remain on the trees in this abnormal 
position. High winds may be the cause. (T. H.)

Feb. 27, 1892, p. 276, 1 col. 
Describes a disease affecting orchids which causes the pseudo-bulbs and leaves to change 
from green to yellow and black. In one case the diseased portions were cut from the leaves 
and when planted recovered. The editor recommends cutting out diseased portions and 
washing the wound with Condy’s fluid or carbolic acid. (J. F. J.)

Refers to an obscure disease which causes plants to shrivel up on cold, clear nights, with 
dew but no wind. The plants recover when the weather becomes warm. (J. F. J.)

Refers to the destructive nature of the California vine disease and notes the demand of 
various societies in France that the Government prohibit the introduction of vines from 
California and from America in general. (J. F. J.)

off affected leaves. (J. F. J.)

F. Sahut claims to have discovered a new disease of grapevine, due to insects. These 
are red spiders (Tetranychus) , which live upon the lower surface of the leaves, where they 
produce a silky tissue^ rather loose in texture. The leaves attacked in this way turned 
yellow, faded, and soon dropped off. Yiala considers this case to be a mere coincidence, 
since, according to him, the leaves were killed by Plasmodiophora vitis , although the color 
of the spots on the leaves was bright red, not brown, as in the “brunissure.” Several 
correspondents state that this disease seems to start in places near the roads, where it often 
has been observed to remain without going farther. (T. H.)

Notes the presence of an obscure disease in bulbs, due, it is thought, to impaired consti¬ 
tutions arising from unsuitable cultural conditions. (J. F. J.)

liable to be killed by the hot sun [sun scald]. (J. F. J.)
