Bioinputs gain strength with high-impact finding

The discovery of new natural molecules with potential for agricultural use is gaining momentum with studies investigating the interaction between plants and microorganisms. From research conducted by the Federal University of Minas Gerais, the United States Department of Agriculture, and Embrapa Environment, an endophytic fungus isolated from a tropical medicinal plant revealed substances with herbicidal and antifungal action. The fungus, belonging to the genus Fusarium, was collected in a forest area and characterized by molecular biology methods. Even without a precise species definition, the characterization was sufficient to advance the tests. The extract was submitted to bioassays on lettuce and bentgrass seeds, models used to evaluate herbicides. Three substances were isolated and, at specific concentrations, completely inhibited seed germination, with an effect comparable to that of synthetic products such as acifluorfen. Tests with duckweed confirmed the high activity, ...
