Agri-mycin 100, Terramycin, amimycin, and bacitracin at various concentrations, and in some cases with 1% glycerol added, were tested for their effectiveness in controlling potato ring rot. Ring rot was reduced with both Agri-mycin 100 and Terramycin. Effective control was obtained only with Agri-mycin 100 at uneconomically high rates. At these rates, phytotoxicity was evident. Amimycin was completely ineffective. There was some evidence that bacitracin might increase infection although this was though to be an indirect effect. The pH of the treating solution did not appear to alter the effectiveness of Agri-mycin 100 or Terramycin. [ABSTRACT FROM AUTHOR] |
