| Abstract: | Black rot of yam bean has been collected from the market in certain localities of Yunnan Province.The diseased tuber-root is characterized by the black dis-coloration of the interior tissues without conspicuous external symptoms.The evidence at hand indicates that the infection takes place before the digging time, through the dead main tap roots.It is unlikely that it works in the storage. |
