Summary and Conclusions
In tests to compare the accuracy of the ultraviolet-light and the gram stain methods for selecting potato seed stocks free from bacterial ring rot, it was found: (1) That the ultraviolet-light method was just as effective as the gram stain method; (2), that the ultraviolet-light examinations were made in less than one-tenth of the time necessary for the gram stain tests; and (3), that the ultraviolet-light method had additional value in reducing the incidence of other “ascula” diseases.
