Effects of chemical treatments on infestation of Alternaria spp. and Fusarium spp. in correlation with technological wheat quality

In this study, the time of infestation by fungi from genus Alternaria spp. and Fusarium spp. was investigated in different stages of wheat maturity (milk, waxy, and technological maturity); the effects of different fungicides on the yield, technological properties, and content of mycotoxin DON were studied also. The results showed that Alternaria spp. attacked spike and kernel in f lowering and end-f lowering stage, as it was already known for Fusarium species. Fungicide treatment increases the yield up to 20%, test weight by 3.7%, and thousand-kernel weight up to 19.1%. High content of mycotoxin DON, above tolerable limits, was detected only in the treatment with fungicide Caramba and in untreated control

Mycobiota of Serbian wheat grain in 2010

This research focused on the assessment of the infection level of sampled wheat grains with phytopathogenic fungi. The samples were taken from the localities Rimski Šančevi and Sombor. The research investigated the impact of localities to intensity of fungal infection by fungi from genus Fusarium and Alternaria. Isolates from genus Fusarium and Alternaria were determined to species level. Pathogenicity of Fusarium and Alternaria isolates from different localities to wheat seedlings was also established.
