In vitro Efficacy of Fungitoxicants on the Growth of Fusarium oxysporum f.sp.carthami Isolates Causing Wilt of Safflower
Subscribe/Renew Journal
Fusarium oxysporum f.sp. carthami causes wilt of safflower and results in a considerable yield loss. The efficacy of five fungitoxicant at 1,10,25,50,100,500 and 1000 μg/ml concentrations were tested against nineteen isolates of Fusarium oxysporum f.sp.carthami. As the concentrations of fungitoxicants increased, the per cent inhibition also increased. Carbendazim was best fungicide for inhibiting the growth of Fusarium oxysporum f.sp.carthami followed by Propiconazole, Thiram, Captan and Copper oxychloride. Even 1g/ml of Carbendazim was equal or better than 1000 μg/ml of rest of the fungicides in inhibiting the growth of Fusarium oxysporum f.sp.carthami.
