Incidence and distribution of Fusarium species associated with feeds and seeds from Spain.

Samples of seeds and feeds (corn-based and mixed) were collected during surveys in 1991-92 and 1992-93 from two regions of Spain, one in northern Spain where the annual rainfall is over 900 mm, and the other in southeastern Spain where the annual rainfall is about 400 mm. The level of Fusarium contamination was determined in the 657 samples analysed, and results were analysed statistically to assess the effects of type of sample and meteorological conditions on Fusarium proliferation. The predominant Fusarium species was Fusarium moniliforme, which represented 92.2% of the total Fusarium strains isolated. Other species isolated were Fusarium oxysporum (5.9%), F. oxysporum var. redolens (0.6%), Fusarium poae (0.6%) and Fusarium sporotrichioides (0.6%).
