fungus, Beauveria bassiana from different geographic regions, i.e.
Coahuila, Nuevo Leon and Tabasco were assessed for their in vitro and in vivo
antagonistic activity in tomato Solanum lycopersicum L., against soil
borne disease, Fusarium oxysporum f. sp. lycopersici race 3.
strains were assessed in vitro (dual culture technique, lytic enzyme
production and inhibition potency of culture filtrates). Strain 1215 was used
to control F. oxysporum f. sp. lycopersici race 3 in tomato
plants in vivo. The strain was applied to soil, foliar sprayed or stem
injected, and plant development determined.
strains inhibited pathogen growth collapsing the mycelium, but only B.
bassiana strain 1215 inhibited growth of F. oxysporum f. sp. lycopersici
race 3 efficiently with 72% when applied in to the medium two days earlier.
Lytic enzyme inhibited up to 21% of the growth of soil borne fungal pathogen
in vitro. Application of B. bassiana strain 1215 to soil decreased by
1.4 the plant index disease without any adverse effect on plant height and
the most efficient was B. bassiana strain 1215, which reduced the
growth of F. oxysporum f. sp. lycopersici race 3 in vitro and
decrease disease development in vivo without any adverse effect on plant
height and root development and can be used as biological control agent
against certain fungal pathogens.
