Brazil has taken another step forward in sustainable agriculture with requests for the first registrations of biological fungicides based on Trichoderma yunnanense. These products highlight the growing role of biological solutions in controlling soil-borne diseases while reducing reliance on conventional chemistry.
What’s New?
Two registration processes are currently underway:
- Total Biotecnologia has submitted applications for two products (provisionally identified as DEF-MIC-052-23A and DEF-MIC-052-23A-1).
- Ihara has requested approval for a product under the Kouken brand, formulated with Trichoderma yunnanense strain IHA02.
If approved, these would be the first fungicides based on this species registered in Brazil.
Why Trichoderma yunnanense?
Belonging to the well-known Trichoderma genus, T. yunnanense is recognized for its biological control activity against major soil-borne pathogens such as Sclerotinia, Rhizoctonia, and Fusarium. Its mechanisms include rapid root and soil colonization, competition with pathogens, and mycoparasitism -while also supporting plant health and vigor.
A Strong Signal for Sustainable Agriculture
Brazil is already a global reference in biological crop protection, and these registration requests reinforce the country’s commitment to innovative, low-impact plant protection tools aligned with integrated pest management (IPM) strategies.
For growers, these developments may soon translate into new biological options to manage diseases more sustainably – an area Lexagri continues to closely monitor worldwide.
