ROJAS BADIA, Marcia M; SANCHEZ CASTRO, Daymara; ROSALES PERDOMO, Katia  e  LUGO MOYA, Daysi. Antagonism of Bacillus against fungi of the genus Fusarium, pathogens of vegetables. Rev. Protección Veg. [online]. 2017, vol.32, n.2, pp. 00-00. ISSN 2224-4697.

The objective of the present work was to determine the effect of Bacillus isolates against the phytopatogenic fungi Fusarium oxysporum and Fusarium moniliforme. The antagonistic at seven and fifteen days effect of 14 stains of Bacillus against two Fusarium species was determine. In the antagonistic assay against F. oxysporum, nine bacterial isolates kept the fungal inhibition over 80 % for seven and fifteen days. In the experiment against F. moniliforme, only six isolates showed inhibition percent of over 50 % after 15 days of incubation. In this work the high potential of new isolates of Bacillus as antagonists of Fusarium, phytopatogens of vegetables crops, was demonstrated. RCGr32, RCQ7, and RCGr33 were selected as the best promising isolates for the biological control of these fungi
