Dose-dependent antifungal effect of L1 against Botrytis cinerea A1 at 4 °C. Inhibition of mycelial growth (by measuring the colony diameter) was observed in the presence of L1 ((A): 0 ppm, (B): 2 ppm, (C): 4 ppm, (D): 6 ppm, (E): 8 ppm, (F): 10 ppm) and compared with the commercial fungicide fenhexamid ((A): 0 ppm, (B): 2 ppm, (C): 4 ppm, (D): 6 ppm, (E): 8 ppm, (F): 10 ppm). Since both L1 and fenhexamid stock were dissolved in DMSO (vehicle), DMSO alone was also tested, adding the same concentration used with either L1 or fenhexamid in each case ((A): 0% v/v, (B): 0.015% v/v, (C): 0.030% v/v, (D): 0.045% v/v, (E): 0.060% v/v, (F): 0.075% v/v) (DMSO [eq]). In all cases, the experiments were performed in biological triplicate.
