Resumo: | Toxigenic fungi that infect corn grains are among the major problems in Brazil as they are associated with toxicological implications for both humans and animals. Mechanical-physical methods have been used to separate contaminated grains in lots of corn kernels based on the symptoms caused by fungi. The objective of this study was to assess whether the presence or the type of symptoms were associated with fungal incidence and total fumonisin levels in corn kernel samples from the field. Kernels of two hybrids were separated visually into three groups: 1) asymptomatic or symptomatic exhibiting 2) kernel rot or 3) kernel streak symptoms. A high frequency of Fusarium spp. was observed in asymptomatic (69.5%) and kernel rot (69.9%). Stenocarpella sp. and Penicillium sp. were found in kernel rot (16.0%) and kernel streak (44.1%), respectively. High fumonisin levels (7.24 μg.g-1), above the maximum tolerated limit, were detected only in kernel rot. No association between fumonisin levels and the frequency of Fusarium spp. in kernels was found. |
