Treatments	Mean mycelial radius of P. nicotianae (cm) ± standard deviations (SD)	Mean mycelial radius of Trichoderma sp. (cm) ± (SD)	Mean% of inhibition in growth ± (SD)
Trichoderma asperellum strain IMI393899	1.48 ± 0.10	2.50 ± 0.10	58.77 ± 2.80 a
Trichoderma atroviride strain TS	1.31 ± 0.08	2.69 ± 0,08	63.50 ± 1.93 b
Phytophthora nicotianae isolate Ph_nic	3.59 ± 0.00	–	–

In the fourth column, values with different letters are statistically different according to Tukey’s honestly significant difference (HSD) test (P ≤ 0.05).
