The aim of this paper was to determine the efficacy of some bioproducts based on useful bacteria from the genus Bacillus and Pseudomonas against the phytopathogenic Sclerotium cepivorum fungus wich causes white rot in onion crop.The selected bacterial strains for this study were: Bacillus subtilis Us.a2, isolated from rhizosphere of green garlic, with deposited DSMZ number 23654; Pseudomonas chlororaphis Sal.c2, isolated from rhizosphere of lettuce; Bacillus pumilus OS.15 and Bacillus amyloliquefaciens OS.17 strains isolated from rhizosphere of onion and Bacillus subtilis 98a isolated from wheat straw. The five strains, besides other important biological features such as lithic enzyme production, mobility, action to stimulate plant growth, showed in vitro antagonistic ability against Sclerotium cepivorum. In order to be tested in vivo, the strains were formulated as microemulsion (which can be applied as seed treatment) and alginate beads (which can be distributed in rows along with the seeds). The tests were performed in growth chamber conditions by using artificially infected soil.Results showed a moderate or similar efficacy of bioproducts compared with the chemical control Topsin 500 SC.
