Abstract/Contents:"In agar culture [agriculture], Trichoderma aureoviride inhibited the growth of Pythium aphanidermatum, the cause of turfgrass root rots. It covered the P. aphanidermatum colony and produced large numbers of conidia. The effective concentration was at 4.65 × 106 cfu/mL, and the inhibitory effect reached 53.56%. Comparing the inhibition effect of T. aureoviride suspension with that of three kinds of fungicides, T. aureoviride at a concentration of 107 cfu/mL had the same effect as 25% metalaxyl with inhibition rates of 77.37% and 79.57%, respectively. Microscopic observation showed that T. aureoviride either entwined the hyphae of P. aphanidermatum or grew parallel with them, then penetrated and parasitized them. The main antagonistic mechanism of T. aureoviride against P. aphanidermatum was hyperparasitism."
