TABLE 3.

Biocontrol effect of Iturin A and Fengycin A on potato leaflets in vitro.

	Disease index (DI)

Treatments	Disease prevention (DP)	Disease therapy (DT)
Control	77.93.99^a	76.13.87^a
Iturin A	22.21.09^b	32.61.60^b
Fengycin A	14.50.69^c	25.71.33^c
I + F	6.20.29^d	10.10.49^d
Metalaxyl	4.90.26^d	7.60.36^d

Control (distilled water); I + F: Iturin A (25 μg/mL) + Fengycin A (25 μg/mL), 1:1 in volume; Metalaxyl (10 μg/mL), the same below. Data are presented as the average (total 36 leaflets per treatment) ± the standard deviation. Different letters a–d in the same column indicate a significant difference in DI between treatment groups (P < 0.05).
