Abstract
Field wheat panicles infected with and without wheat head blight were collected in 2012 from Jiangsu province where Fusarium Head Blight (FHB) is prevalent. The collected panicles infected with FHB were assessed in the laboratory for Disease Severity Levels (DSL). A series of wheat samples with varying Rate of Diseased Panicles (RDP) and varying DSL were prepared by adding diseased panicles to healthy ones and analyzed using Ultra-Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC-MS/MS) for their Deoxynivalenol (DON) and Deoxynivalenol-3-Glucoside (D3G) contents. Consistent increases of DON and D3G levels were observed as the RDP and DSL of the wheat samples were enhanced, showing a distinct linear correlation between disease index (DI) of wheat head blight and DON and D3G content. The linear regression models were calculated as Y DON =257.78X DI +2315.61 (r=0.96) and Y D3G =41.81X . The models were validated with field samples collected in 2013 and showed a good fit for variation trends, but overestimated DON content and underestimated D3G content.
