The young tender stems ma}^ become affected and the plants killed when conditions are favorable for the parasite; or it some- times appears later on the pods, as well as on other parts of the plant. The disease is very noticeable on the yellow pods of wax varieties, which are reduced in value or rendered unfit for market purposes. Figure 62 illustrates the dis- eased pods. The Cornell Station (Cor- nell Station Bulletin 255, p. 436) makes the following statement in regard to this disease: "The spots or cankers are black with reddish or yellowish mar- gins. IMost growers are also familiar with the disease on the seed itself, espe- ciallv on the white beans, where it makes rusty, red spots of various sizes, sometimes involving nearly the entire seed, though ordinarily onl}' producing a slight discoloration on one side. The disease enters the seed by way of the pod, the fungus penetrating from the outside into the young and tender seed. . When the diseased seeds are planted in the soil, and first come through the ground, the_v are sure to show the small black cankers on the cotyledons or seed leaves and a little later on the ;.
