Disease incidence (DI) of oil palm seedlings challenged with Ganoderma boninense and treated with phenazine and hexaconazole. T2–T5 denote the different treatments: T2, G. boninense inoculated oil palm seedlings; T3, G. boninense inoculated oil palm seedlings treated with 1 mg/ml phenazine; T4, G. boninense inoculated oil palm seedlings treated with 2 mg/ml phenazine; T5, G. boninense inoculated oil palm seedlings treated with hexaconazole. The DI values are recorded at monthly intervals (1–4 mpi). All values are expressed as the means of three biological replicates.
