In a field trial in Florida, USA, 94.1 per cent of true date palms belonging to 5 cultivars (Deglet Noor, Zahidi, Thoory, Medjool and Halawy)developed symptoms of lethal yellowing (LY). MLOs were observed in the phloem of all symptomatic palms. Halawy palms survived infection longer than the other cultivars, and further trials are being conducted on this cultivar. It is suggested that when true palms contract LY, the lateral shoots may survive and grown into mature palms.
