Abstract

The level of Botrytis cinerea Pers ex Fr. on cabbages stored for 6.5 months in a cold store (+1 °C) and the subsequent number of merchantable cabbages were extremely reliably predicted by the B, cinerea contents of cabbages stored for 7 weeks at 5-10 °C, or 3.5 months at +1 °C. The cabbages were probably infected by B. cinerea in the field 3 weeks or more before harvesting. The fungus could still be controlled satisfactorily by spraying with fungicide 4 weeks before harvesting.
