Effects of compound TPG1 on the development of plant diseases. (a) Control efficacy of TPG1 isolated from Trevesia palmata against seven plant diseases. RCB, rice blast; RSB, rice sheath blight; TGM, tomato gray mold; TLB, tomato late blight; WLR, wheat leaf rust; BPM, barley powdery mildew; PAN, pepper anthracnose. (b) Representatives of the plants treated by TPG1. Plants were inoculated with spores or mycelial suspensions of phytopathogenic fungi one day after treatment with TPG1. 1, treatment with a chemical fungicide as a positive control; 2–4, treatment with 500, 250, 125 μg/mL of TPG1, respectively; 5, treatment with the Tween 20 solution containing 5% methanol as a negative control. The bars represent the mean ± standard deviation of two runs with three replicates. Asterisks indicate significant difference compared with negative controls by Tukey’s test (**p < 0.001, *p < 0.01).
