Whereas CK—control without the use of bio-pesticides, C—use of 0.50 g L⁻¹ Chitosan, L—use of 10.00 g L⁻¹ Lentinan, N—use of 0.05 g L⁻¹ Ningnanmycin, CL—Chitosan plus Lentinan, CN—Chitosan plus Ningnanmycin, LN—Lentinan plus Ningnanmycin, CLN—Chitosan plus Lentinan plus Ningnanmycin. All the above treatments were applied by means of root irrigation with 200 mL, foliar spraying with 200 mL, and then inoculated with PRSV virus. *—p < 0.05, **—p < 0.01, ***—p < 0.001, Ns—not significant.
