Toyama Agricultural Experiment Station reported that it was very effective for control of Sclerotinia rot of Chinese milk vetch (Astragalus sinicus L.) to mow the tops of the vetch in autumn. The writer made field tests to confirm the result. When the top of vetch plants was cut off with scissors and the plant fragments were carefully removed from the plots, the number of affected plants was less, giving higher yield, than the untreated plots. But when the top of vetch was mowed with mower or specially designed sickle, the development of the disease was as much or more severe, as compared with the check. The explanation is that the cutting fragments remained in the plots may serve as a nourishing substratum for the fungus, which become vigorous enough to pass over to the vetch plants.
