Sodium 2,4,5-trichlorophenate (Dowcide B) (D-B) is used generally as a postharvest dip for Gladiolus corms in the control of Fusarium oxysporium f. sp. gladioli Synd. and Hans. D-B solutions were reduced gradually in fungicidal effectiveness and the pH was reduced similarly when used continuously for dipping corms. The end point for renewing solution was determined in terms of pH and number of corms treated.
