Incidence of gray mold (% of affected berries) in ‘Benitaka’ table grapes after 30 and 45 days of storage in cold chamber at 1 ± 1 °C and 3 days at shelf-life at 22 ± 1 °C after the period of cold storage, individually packaged in clamshells with different SO₂-generating pads and perforated plastic liners, inoculated with 10⁶ spores mL⁻¹ Botrytis cinerea.
