Protection of grape berries from B. cinerea infection by treatment with 4 at 50 µM.

	DI ± SE a	Asymptomatic Berries (%) ± SD a
Control	1.93 ± 0.14	17.5 ± 8.7
Treated	1.03 * ± 0.24	51.25 * ± 18.0

^a Symptoms are expressed as Disease Index (DI) ± standard error (SE). The mean percentage of asymptomatic grape berries ± standard deviation (SD) was also calculated. Four independent infection experiments were performed for each treatment. Data were statistically analyzed by t-test. * indicates significant differences at p < 0.05.
