FIGURE 7.

The in vitro antagonism assays using T. harzianum against the phytopathogenic fungus S. sclerotiorum (white mold). (A) Results obtained with the unencapsulated fungus, showing that the fungus was able to control the phytopathogen, according to the classification scale (Bell et al., 1982), but that there was the formation of white mold sclerotia (indicated by the arrows). (B) Results using the fungus encapsulated in wet microparticles. (C) Results using the fungus encapsulated in dried microparticles, indicating that the encapsulated fungus was a satisfactory antagonist.
