In July 2015 and 2016, an unusual disease was observed on scapes of approximately 10% of field-grown elephant garlic (Allium ampeloprasum var. ampeloprasum) growing in a field in Newark, New York. Symptoms were sunken lesions up to 50 mm long, causing twisting, girdling and collapse of the scape. Lesions were initially cream to tan-coloured and became orange with the production of numerous acervuli without setae. Symptoms were confined to the scape. Although scapes are often removed to improve bulb yield, the disease is of importance where scapes are intended for fresh market sale, or where bulbil production is required for propagation.
