Real and statistical processing of barley yield data naturally contaminated with fusariotoxin
Asen Nikolov, Nadezhda Sertova, Maya Ignatova
Abstract: Fumonisins are produced by fungi of the genus Fusarium spp., which are widely spread out in the nature. They are produced during grain growth, ripening and harvesting and are known as “field mycotoxins“. Fusarium species can produce compounds that are toxic to animals and humans. In this study, the development of Fusarium toxins was determined in healthy and mechanically damaged barley grains treated and untreated with fungicide, respectively, under natural contamination. It was found that healthy kernels treated with fungicide had the highest yield of 6700 kg.ha-1 followed by the yield of damaged kernels treated with fungicide. The lowest yield of 4850 kg.ha-1 was reported for the damaged and untreated barley grains. The two treatments whose plants were treated with fungicide had a higher yield than their counterparts, i.e. the plants not treated with fungicide. In confirmation of this by mycotoxicological analysis was established the presence of fumonisin 0.234 in healthy seeds untreated with fungicide and 0.274 in mechanically damaged untreated seeds. Fumonisin concentrations were measured by using Enzyme-Linked Immunosorbent Assay (ELISA) method. The used approach in this study shows that fungicide treatments effectively reduce mycotoxin levels in barley and increase grain yield. The use of fungicides should be combined with other infection mitigation strategies, such as avoiding mechanically damaged grains, which are a suitable substrate for mycotoxins production. These measures will help to improve food and feed safety.
