Abstract

Fusarium wilt of tomato, caused by Fusarium oxysporum f. sp. lycopersici (Fol) is a common disease in tomato. The arbuscular mycorrhizal fungus (AMF) Rhizophagus intraradices (previously called Glomus intraradices) was evaluated on its bioprotective ability against Fol in tomato cv. Missouri plants. Pathogenicity assays with Fol isolates from races 1, 2 and 3, showed that races 2 and 3 are the most aggressive for this cultivar, being the isolate R3C5 from race 3 the most virulent one. The results using this isolate showed that root rot index (RRI) caused by Fol is lower in tomato mycorrhizal plants grown under a low phosphate (20μM) fertilization regime (Fol +AMF +Pi 20μM) compared to non-colonized plants (Fol +Pi 20μM). Fol infested plants subjected to high phosphate (200μM) fertilization (Fol +Pi 200μM) had an intermediate RRI value that was not significantly different in the two treatments. These findings suggest that R. intraradices confers tolerance to Fol in tomato cv. Missouri plants and that this mechanism may partially be influenced by improved phosphate nutrition.
