“…Fungal isolates Bipolaris sorokiniana 98004 (Cruz Alta -RS), 98012 (Lagoa Vermelha -RS) and 98032 (Engenheiro Beltrão -PR) were selected based on results obtained in previous pathogenicity tests (Minotto et al, 2014).…”

Streptomyces sp. R18(6) and Streptomyces sp. 6(4) strains were evaluated for their ability to control brown spot and common root rot caused by Bipolaris sorokiniana in wheat crops. The antifungal activity of these isolates was tested using a double-layer assay and culture pairing at 28 °C. Physiological and enzymatic activity performed through siderophore, indole-3-acetic acid, nitrogen fixation and phosphate solubilization tests. The biocontrol of the disease and growth-promoting efficiency of wheat seedlings were assessed using in vivo assays in a greenhouse. In the culture pairing assays, both strains inhibited B. sorokiniana mycelial growth, while in the double-layer only Streptomyces sp. R18(6). Streptomyces sp. 6(4) produced auxin, siderophores, fixed nitrogen and solubilized phosphate, whereas R18(6) did not produce siderophores. In the greenhouse assays, strain R18(6) showed statistical differences in shoot dry mass and root dry mass compared with those of strain 6(4) in the presence of the phytopathogen (P ≤ 0.05), and these results were more evident when the environmental temperature was higher. In the absence of the phytopathogen, Streptomyces sp. 6(4) strain increased the root dry mass compared with that of the control during the same period. Therefore, these isolates can potentially control root rot and brown spotting and may promote the growth of wheat plants.

The objective of this research was to evaluate the response of wheat plants to the application of possible elicitor compounds against Bipolaris sorokiniana pathogen. This response was measured through the quantification of antioxidant enzymes, malondialdehyde and flavonoids, evaluation of the severity of brown spot disease and productivity in wheat, greenhouse and field crops. The treatments consisted of suspensions of endophytic fungi Aspergillus japonicus and Trichoderma tomentosum, salicylic acid, acibenzolar-S-methyl and fungicide. In the field trials, in 2015 and 2016, the development of the disease was lower and productivity was higher in all treatments, with emphasis on the fungicide. However, endophytic fungi suspensions demonstrated potential as growth promoters, disease severity reducers and protective antioxidant response activators, as they promoted significant increase in superoxide dismutase, catalase, glutathione and flavonoid enzymes.
