Fungal antagonists Trichoderma viride, T. harzianum, T. hamatum, T. koningii, T. pseudokoningii and the bacterial antagonists, Pseudomonas fluorescens and Bacillus subtilis were effective against Fusarium f. sp. cepae in in vitro conditions. Combined seed treatment of T. viride + P. fluorescens reduced the onion basal rot incidence both in pot and
in field conditions.
