Recent occurrence of Fusarium wilt caused by Fusarium oxysporum on marjoram in Argentina
Australasian Plant Disease Notes 2 (1), 115-116
Abstract: In spring 2006, marjoram (Origanum vulgare) plants were found decayed and collapsed in Cordoba Province, in Argentina. Disease symptoms consisted of wilting, foliar necrosis, vascular discoloration, and death of infected plants. Several fungal isolates were obtained and identified as Fusarium oxysporum. Koch's postulates were completed. This appears to be the first record of a recent occurrence of Fusarium wilt of marjoram caused by this pathogen in Argentina.
