“…Otane was commonly grown in the North Island, and two of the three CRDW17 crops were grown in South Canterbury, which contributed to the slightly higher mean infection levels in these regions compared with others. In an earlier study, Sayer & Lauren (1991) also found consistently higher infection levels in North Island crops than in those from the South Island. Rainfall during flowering is a major contributing factor to FHB development (Parry et al 1995) and may explain some of the regional differences in our study.…”

Samples of grain from 40 New Zealand wheat and barley crops harvested in 2000 were assayed for Fusarium infection. Grain from all crops was infected, and Fusarium incidence ranged from 3 to 52% of grains infected, with a mean of 14%. Incidence of Fusarium was higher in spring wheat than in autumn wheat or spring barley. The highest level of infection (52% grains infected) was found in Otane wheat (highly susceptible to Fusarium head blight) sown into a paddock after maize, although there were no general effects of cropping history on grain infection. Levels were lower when residues of the previous crop were burned rather than baled or incorporated. Infection levels varied between cultivars, corresponding to the variability in susceptibility to Fusarium head blight.

“…In recent years, Fusarium diseases (crown rot, root rots and Fusarium head blight) have become of increasing concern in New Zealand cereal crops. These diseases are caused by complexes of Fusarium species, and the species mixture varies between regions (Sayer & Lauren 1991).…”

“…Hussein & Baxter (1985) reported on the incidence of Fusarium species in maize grown in the Manawatu, and Sayer & Lauren (1991) found 22% of the Waikato maize samples they examined in 1987, 1988, and 1989 to have levels of Fusarium infection> 20%. Fungal infection of grain may result in off-flavours, reduced palatability and nutritive value, and contamination by mycotoxins.…”

“…is known as a disease leading to considerable reduction of grain yield and grain contamination with secondary metabolites of the pathogens. Seed infection by the fungi results in its reduced germination, seedling blight, root as well as foot rot (Sutton, 1982;Che/kowski et al, 1988;Scott et al, 1988;Wilcoxson et al, 1988;Daamen et al, 1991;Sayer & Lauren, 1991). Fusarium produces phytotoxic compounds and also a variety of metabolites toxic to humans and animals (Che3kowski & Mafika, 1983;Che2kowski et al, 1988b;Kiecana, 1988;Kiecana et al, 1988;Chelkowski et al, 1989;Adler et al, 1990;Snijders & Perkowski, 1990).…”

Reaction of triticale, wheat and rye accessions to graminaceous Fusarium spp. infection at the seedling and adult plant growth stages

1993

Pathogenicity of 20 isolates of 12 Fusarium species recovered from triticale seed against seedlings of 14 varieties of winter cereals (triticale, wheat, and rye) was tested. The most pathogenic inoculum was a mixture of isolates (a composite isolate) of all the species. The following species were individually the most pathogenic: E avenaceum, E culmorum, E sambucinum var. coeruleum, and E graminearum. Winter triticale was more resistant to seedling blight than rye but more susceptible than wheat.Also reactions of 31winter and 12 spring varieties of cereals to head inoculation with a composite isolate of 4 Fusarium spp. ( E avenaceum, E culmorum, F. graminearum, and F. sambucinum var. coeruleum) was studied. In comparison to other cereals of similar type winter and spring wheat appeared to be the most susceptible while winter rye reaction was comparable to winter triticale. Spring and winter triticale varieties responded to head infection intermediately.There was no significant correlation between seedling and head reactions to infection with Fusarium spp. for winter rye and triticale. For winter wheat a negative trend was found. The above findings imply that screening of cereals at the seedling stage can not be used to predict the resistance to head blight. Nevertheless, resistance at the stage is highly desirable to prevent excessive damage of the crops due to the seedling blight incited by Fusarium spp..
