THE DISEASE 

 ECONOMIC ASPECTS 



Name, history, and geographical distribution 

 The name bean anthracnose, generally applied by American, English, 

 French, Italian, and other pathologists to the disease under consideration, 

 was apparently first used in this connection by Scribner (1888), although 

 the name anthracnose was used earlier to designate the grape disease 

 caused by Gheosporium ampelophagum Sacc. The terms pod spot, or 

 canker, and leaf spot are sometimes applied to the disease as it occurs on 

 these respective parts of the plant; while not uncommonly the terms rust 

 and blight, and rarely scab, are erroneously used by laymen. Frank 

 (1883 b) called the disease Fleokenkrankheit, and the names Brennerflecken, 

 Brennerfleckenkrankheit, Brennfleckenkrankheit, and Schwarzflecke7ikra?ikheit 

 have been used by German writers. In Holland, Schenk (1917) speaks 

 of the disease as Vlekziekte, and in Denmark it is called Bonnesyge by 

 Lind (1910). 



The disease was first definitely described by Saccardo (1878), who 

 reported its discovery by Lindemuth in the fruit and vegetable garden 

 of the Agricultural Institute of Poppelsdorf, at Bonn, in August, 1875. 

 Anthracnose spots are present, however, on specimens of bean pods 

 distributed by Desmazieres (1843b) under the name Septoria leguminum 

 Nob. Berkeley (1880) reports the disease on kidney beans from Bedford, 

 England, ascribing it to Ascochyta. Saccardo (1881) shows a good colored 

 reproduction of a pod affected with anthracnose, and drawings of the 

 fructifications of the fungus. The label indicates that the fungus was 

 collected at Padua in June, 1875, on Phaseolus vulgaris. Frank (1883 b) 

 states that Lindemuth reported to him the occurrence of the disease 

 in 1875 on the red-mottled Zucker-Stangenbrechbohnen, and a few 

 years later on numerous other varieties grown in the same vicinity. 

 Frank himself says the disease occurred in other parts of Germany in 

 1881 and in various localities in 1882, it being especially severe the 

 latter year. He gives an excellent account of the disease and its cause 

 in the article cited. Saccardo (1884) mentions the disease as being 

 common and injurious in Germany, Italy, France, England, and North 

 America. Richon (1889) records its presence in the Marne district of 

 France.
