138 BOARD OF AGRICULTURE. [Jan., 



Among' quince diseases, the leaf blight, and fruit spot 

 (Entomosporium niaculatum, Lev.). 



Among apricot diseases, the fruit rot (Monilia fructigena, 

 P.) and the leaf spot (Cylindrosporium padi, Karst.). 



Among cherry diseases, the fruit rot (Monilia fructigena, 

 P.) and the leaf spot (Cylindrosporium padi, Karst.). 



Among peach diseases, the fruit rot (Monilia fructigena, 

 P.) and the leaf curl (Exoascus deformans, Berk., Eckl.). 



Among the plum diseases, the fruit rot (Monilia fructigena, 

 P.) and the leaf spot (Cylindrosporium padi, Karst.). 



Among grape diseases, the anthracnose (Sphaceloma 

 ampelinum, D. By.), the black rot (Laestadia bidwellii, Ell., 

 V. & R.), the brown rot or downy mildew (Plasmopora viticola, 

 B. & C. Berl. & De T.), and the powdery mildew (Unicinula 

 spiralis, B. & C). 



Among currant diseases, the leaf spots (Septoria ribes, 

 Desm.), and Cercospora angulata, Wint.). Also anthracnose 

 (Gloeosporium ribis, Lib., Mont. & Desm.). 



Among gooseberry diseases, the leaf spots (Septoria ribes, 

 Desm.), and Cercospora angulata, Wint.). The gooseberry 

 mildew is better controlled by use of liver of sulphur than by 

 the Bordeaux mixture treatment. 



Among diseases of vegetables amenable to the Bordeaux 

 mixture treatment are: The early blight of the potato (Al- 

 ternaria solani, E. &']\L, J. & G.), the late blight of the potato 

 (Phytophthora infestans, D. By.), the mildew of the cucumber 

 (Plasmopora cubensis, M. B. & C), the leaf blight of celery 

 (Cercospora apii, Fres.), and the leaf spot of celery (Septoria 

 petroselina, Desm., var. Apii, Br. & Car.). 



Jt must not be inferred that proper treatment with Bor- 

 deaux mixture proves equally successful in controlling each 

 of the diseases named, nor that such treatment is always profit- 

 able. It has been demonstrated, for example, that the ripe rot 

 of fruits, which is caused by Monilia, cannot always be kept 

 under satisfactory control by practical treatments; also that 

 raspberry anthracnose may be successfully treated with Bor- 

 deaux mixture, but the expense of the treatment outweighs the 

 advantages of the treatment which are gained. It is profitable, 

 therefore, for one who undertakes to treat a plant disease with 

 the Bordeaux mixture, to post himself as to the particular 

 treatment which the case in hand demands.
