Occurrence of spores of Tilletia laevis and T. tritici in wheat deliveries in western Victoria

Samples of wheat grain delivered to five receival centres in western Victoria during the 1987188 harvest were examined for the presence of spores of Tilletia laevis and T. tritici. Of the 217 samples, 64 (29%) were contaminated with trace amounts of spores, predominantly those of T. tritici. All but two samples were from crops grown from seed which had been treated for bunt control.
