Popis:	Six fungicides at three rates (1.5x, 1.0x and 0.5x mg a.i/ml) were evaluated on radial growth and and regrowth of mycelia of Fusarium pallidoroseum isolated from castor (Ricinus communis) in vitro. It was observed that the fungicides (Benomyl, Benomyl + Thiram, Mancozeb, Metalaxyl-m + Thiomethoxan + Difenconazol, Tricyclazole and Carbendazim + Mancozeb) at all the concentrations tested inhibited mycelial growth and regrowth of the fungus. Benomyl, Benomyl + Thiram and Tricyclazole completely inhibited mycelia growth of fungus at 1.5x, 1.0x and 0.5x mg a.i/ml. Metalaxyl-m + Thiomethoxan + Difenconazole, Carbendazim + Mancozeb partially inhibited radial growth and re-growth of mycelia only at 1.5x mg a.i/ml, not at 1.0x and 0.5x mg a.i/ml. The inhibitory effect of all the fungicides on mycelia growth and re-growth was greatest at 1.x5 mg a.i/ml.
