Abstract:
Control of root rot and wilt on Kangaroo Paw (Anigozanthos) caused by Pythium myriotylum was tested, using artificial inoculations, in greenhouse experiments. Disease incidence in the inoculated but non-treated plots was 74% in Expt A (1999) and 46% in Expt B (2000). Disease incidence was significantly reduced by treatments with fenamidon (26 and 70%) and Terraclor SuperX (65 and 41%) in Expts A and B, respectively, in comparison with the non-treated plots. Disease incidence was reduced with Ridomil Gold by 7 and 48% in Expts A and B, respectively; with Dynone by 22 and 41% in Expts A and B, respectively; with Tachigaren by 20% in both experiments; and with Trichoderma harzianum treatment, disease incidence was reduced by 9% only in Expt B. Yields (recorded only in Expt B) obtained in plots inoculated with P. myriotylum were significantly lower than in the non-inoculated control plots. The most efficient treatment was fenamidon, with 324% more flowers than in the non-treated control. The number of flowers in terraclor SuperX, Ridomil Gold, Dynone and T. harzianum treatments was higher by 285, 249, 234 and 235% than in the non-treated control. In vitro tests demonstrated that the most effective doses, causing 50% inhibition of mycelial growth (ED50), were 0.09, 0.4, 0.4 and 4 μg/ml for the fungicides fenamidon, Ridomil Gold (mefenoxam), Terraclor SuperX (etridiazole + quintozene) and Dynone (prothiocarb), respectively. © 2005 Blackwell Verlag.
