Abstract:
The plant growth promoting fungus Fusarium equiseti GF183 effectively controlled Fusarium wilt of spinach caused by Fusarium oxysporum f. sp. spinaciae in transplanting systems using paper pots. Reduction in disease severity ranged from 43.5 to 91.8%. Double application of F. equiseti GF183 increased the protective effects. The number of colony-forming units of F. oxysporum f. sp. spinaciae per gram fresh weight of roots was significantly reduced (P<0.05) in plants treated with F. equiseti. Root extracts from both F. equiseti-treated plants and F. equiseti and pathogen-treated plants significantly inhibited new production of budding-cells of F. oxysporum f. sp. spinaciae.
