Fusarium moniliforme Sheldon — Pathogenicity to Wheat Seedlings and Ability to Produce Fumonisins

Abstract

AbstractAll 17 examined Polish isolates of Fusarium moniliforme Sheldon [syn. F. verticillioides (Sacc.) Nirenberg], originating from wheat, maize and barley kernels, exhibited pathogenicity to wheat seedlings of the cultivar ‘Almari’ (5 isolates‐very strong, 3 strong, 3 medium, 5 weak and only one very weak). The same isolates were able to produce the mycotoxins fumonisins on rice under laboratory conditions. Fumonisin B1 (FB1) was detected in concentrations ranging from 1.3 to 2240mg/kg and fumonisin B2(FB2) from 0.7 to 600 mg/kg. The yield of the fumonisins produced in vitro was not related to the pathogenicity of individual isolates.
