For the oat cultivar, we found even more substantial endophyte associated increases in mean seedling length. The increases in mean seedling length were greatest for the combined fungal endophyte and fungicide treatment. We found significant increases in mean barley seedling length induced by the endophytes after 28 days of seedling growth at time points of up to 6 months from seed dressing. We tested a range of seed dressings to evaluate the effects of the endophytes: untreated seed, regular fungicidal dressing (triticonazole and prochloraz), endophyte seed spore dressing and a combination of endophyte and fungicide. We hypothesised that a consortium of fungal endophyte species applied as a seed spore dressing may improve the germination and subsequent growth of barley and oat seedlings. Root endophytic fungi have been shown to improve agronomic traits in spring barley and may be less sensitive to the regularly applied foliar fungicides. The use of beneficial fungi as crop inoculants is constrained by the need for application of fungicides because the pathogen controlling fungicides often concurrently suppress the efficacy of the beneficial mycobiont.
