Fig 1. Geographic distribution of P. verrucosum (A) and OTA (B) occurrence in winter wheat grain collected from on-farm storage bins across Southwestern Ontario, Canada.

¹Total grain samples collected. Open circles and dots represent individual on-farm storage bin operations. ND: bin operations where grain tested negative for P. verrucosum and/or OTA. CFU determined by dilution plating on DCYES media with a LOD: 63 CFU/g; OTA, LOD: 0.3ng/g determined by LC-ESI(+)-MS/MS.
