摘要：

Wheat contamination with fungi leads to quantitative losses and qualitative depreciation due to mycotoxins accumulation. Currently there are no Fusarium-resistant wheat cultivars. There are only medium tolerant varieties to such infections. In the present study, several Fusarium spp. pathogens were isolated from wheat debris and kernels harvested in 2017 from different lines of Triticum aestivum obtained in the experimental field of NARDI Funduleu. Fungal cultures were identified at genus level hosed on their microscopic and cultural characteristics on different nutrient media. Fungal growth inhibition of these pathogens was studied in vitro, using strains of Bacillus amyloliquefaciens (BIR, BPA, OS17 and BW) with biological control potential. The biocontrol efficacy, established by biometric measurements, was in the range of 61.9 to 84.4%. Further studies are required to determine the in vivo effects of these biocontrol bacteria on wheat plants.
