Study points to technological differences among biofungicides

The use of biofungicides in the control of soil-borne diseases has been gaining ground in the Brazilian agricultural market, driven by technological advances and the search for more sustainable alternatives in phytosanitary management. According to a survey conducted by Gabriel Medina, a professor at the University of Brasília, the available products present relevant differences in composition, mode of action, and agronomic performance. The analysis shows that most biofungicides are formulated from the fungus Trichoderma, although there are also solutions based on bacteria of the genus Bacillus. There are products with only one microorganism and others that use microbial consortia, developed from exclusive strains isolated by the companies themselves or in partnerships with public research institutions, always with specific control objectives. The modes of action also vary according to the microorganism used. While fungi act mainly through parasitism on soil pathogens, bacteria ...
