Abstract


The object of this study was to determine the effectiveness of some fungicides such as Dithane M-45 (mancozeb) - 0.3%, Plantvax (oxycarboxin) - 0.075%, Saprol (triforine) - 0.1%, Calirus (benodanil) - 0.3%, Bayleton 5 WP (triadimefon) - 0.05%, Baycor (biloxazol) - 0.1%, Vigilex (dichlobutrazol) - 0.04% in the control of chrysanthemum white rust (Puccinia horiana). Tests were conducted in the period 1979-1980. Plants of four varieties were sprayed 8 times weekly. The disease was completely suppressed in the combinations with Plantvax, Saprol, Calirus, Bayleton 5 WP, Baycor and Vigilex. The disease index of Puccinia horiana infection on chrysanthemums was only slightly lower when Dithane M-45 was applied. Plantvax was phytotoxic for all tested varieties, Vigilex suppressed plant growth, treated plants were 3/4 shorter in comparison with plants of all the other combinations.
