Antifungal activity of compound 1 and compound 2 extracted from C. rosea against plant pathogens B. cinerea and F. graminearum. Conidial suspensions in half-strength potato dextrose broth were inoculated in 96-well microtiter plates containing compound 1 or compound 2. Frequency of germinating conidia was determined 8 hour post-inoculation by counting the number of germinating and non-germinating conidia, while germ tube length was measured using ImageJ software. (A) B. cinerea conidia germination, (B) B. cinerea germ tube length, (C) F. graminearum germ tube length. Abbreviation: 1, compound 1; 2, compound 2. Concentrations of compound are indicated below the bar. Error bars represent standard deviation based on three biological replicates. Different letters indicate statistically significant differences (P ≤ 0.05) within the experiments based on Fisher’s exact test.
