Of 12 wheat samples from crops affected by head blight (caused by Fusarium graminearum) at harvest in the Northern Rivers region of New South Wales in November 1983, 11 contained up to 6.7 mg kg-1 (mean 1.8 mg kg-1) of the trichothecene mycotoxin, deoxynivalenol (DON, also known as vomitoxin). Grain feeds responsible for feed refusal and vomiting in a piggery in the region were found to contain up to 3.7 mg kg-1 of the toxin. Two triticale samples contained 9 and 11mg kg-1 of DON, but 2 barley samples were negative. A wide range of other wheat samples, principally representative of the New South Wales dryland wheat belt, were all, with 1 exception. found free of DON. Since DON can be produced in times of wet harvest, maximum limits for contamination of grains are recommended.

To establish the identity of Fusarium species associated with head blight (FHB) and crown rot (CR) of wheat, samples were collected from wheat paddocks with different cropping history in southern Queensland and northern New South Wales during 2001. CR was more widespread but FHB was only evident in northern NSW and often occurred with CR in the same paddock. Twenty different Fusarium spp. were identified from monoconidial isolates originating from different plant parts by using morphology and species-specific PCR assays. Fusarium pseudograminearum constituted 48% of all isolates and was more frequently obtained from the crown, whereas Fusarium graminearum made up 28% of all isolates and came mostly from the head. All 17 Fusarium species tested caused FHB and all 10 tested caused CR in plant infection assays, with significant (P < 0.001) difference in aggressiveness among species and among isolates within species for both diseases. Overall, isolates from stubble and crown were more aggressive for CR, whereas isolates from the flag leaf node were more aggressive for FHB. Isolates that were highly aggressive in causing CR were those originating from paddocks with wheat following wheat, whereas those from fields with wheat following maize or sorghum were highly aggressive for FHB. Although 20% of isolates caused severe to highly severe FHB and CR, there was no significant (P < 0.32) correlation between aggressiveness for FHB and CR. Given the ability of F. graminearum to colonise crowns in the field and to cause severe CR in bioassays, it is unclear why this pathogen is not more widely distributed in Australia.
