ThzID1-M3 reduced the Fsp population levels (P < 0.05). In soil with the added Fsp, mean estimates of Fsp DNA peaked at day 3, decreased by day 7, and leveled off when ThzID1-M3 was not present.
Fsp DNA slightly increased by day 3 and was undetectable by day 7 when ThzID1-M3 was added, resulting from the inhibition of germination and hyphal growth of Fsp by ThzID1-M3.
