Notes:
Direct harvesting, with mechanical removal of the foliage (topping), of onion crops followed by post-harvest drying at ambient temperatures (c. 18°C) resulted in an increase in the incidence of onion neck rot (Botrytis allii).The disease was substantially reduced if topped onions were dried at 30°C with an airflow of 425 m3 air/h/tonne. The treatment was most effective if the crop was removed from the field for drying within 48 h of topping thus avoiding severe infection of the damaged green tissues of the necks of onions.
