Inhibition of enriched Pd by Tp in AC soil samples. a Soil samples from AC were inoculated with Pd (105 conidia/g soil) in duplicate. Following 7 days post-incubation at 10 °C, Tp at 10-fold (106 conidia/g soil) or 100-fold (107 conidia/g soil) to that of Pd (105 conidia/g soil) was added. Untreated soil (soil alone) and soil containing Tp served as controls. Two aliquots from each sample were processed for the recovery of Pd in culture at week 1, 3, and 5 post-incubation. Approximately, 50 and 67% killing of Pd was observed with 10-fold and 100-fold higher Tp at week 1 post-incubation, which gradually increased to 57 and 72% at week 3 post-incubation and 95 and 84% at week 5 post-incubation. b Soil samples were inoculated with Pd and treated with Tp as explained in a, except that these samples also received 1% millet seeds extract. Addition of millet seeds extract did not enhance Tp killing of Pd.
