Variation in the production of trichothecene mycotoxin deoxynivalenol (DON) in spring barley varieties after treatment with the fungicides azoxystrobin and tebuconazole
Plant Protection Science 41 (2), 58-62
Abstract: Eight varieties of spring barley (Hordeum vulgaris Lin.) were artificially inoculated with a Fusarium culmorum (W.G. Smith) Saccardo - isolate and naturally infected in the middle of the flowering period, and 2 d later treated with the fungicides azoxystrobin or tebuconazol at a dose of 1 l/ha in 250 l of water. In both control and treated samples of grain the content of deoxynivalenol (DON), the main trichothecene mycotoxin produced by F. culmorum, was determined by gas chromatography (GC-ECD). The treatment with either fungicide resulted in elevated levels of DON, an effect that was more pronounced with azoxystrobin.
