19 October 2026, São Paulo: Brazil’s health regulator ANVISA approved post-registration toxicological evaluations for three Syngenta biological fungicides on October 2, alongside similar approvals for four smaller biologicals and biostimulant makers, in a decision published in the Diário Oficial da União on October 7. Unlike a new registration, a post-registration evaluation applies to a product already on the market and lets a company add new approved uses, such as additional crops or target pests, to its label.
The Syngenta products, Arvatico, Certano and Reverb, are all microbiological products built around strains of Bacillus bacteria rather than synthetic chemistry. Arvatico and Certano both use Bacillus velezensis isolate CNPSo 3602 at 150 grams per liter, formulated as a suspension concentrate, and are labeled to control fungal root diseases including Fusarium wilt, Rhizoctonia damping-off and charcoal rot, as well as plant-parasitic nematodes such as the soybean cyst nematode and root-knot nematodes. Reverb combines three Bacillus species, Bacillus subtilis, Bacillus velezensis and Bacillus pumilus, each at 33 grams per liter, and is labeled against a broader range of roughly 35 fungal pathogens across crops including soybean, corn, coffee, sugarcane, wheat, citrus and apple. All three are registered to Syngenta Proteção de Cultivos Ltda. and formulated in Brazil by Tacto Biotecnologia and Total Biotecnologia.
The same resolution, RE 3.944, covered four other post-registration evaluations. Biocaz, a Brazilian manufacturer based in Minas Gerais, gained an evaluation for Biocaz Control, a microbiological insecticide and acaricide based on the fungus Beauveria bassiana, labeled against pests including whitefly, coffee berry borer and two-spotted spider mite across crops such as banana, sugarcane, corn, strawberry and soybean. Ballagro Agro Tecnologia, a Brazilian biologicals maker that distributes products through a partnership with FMC Corporation, had an entry for a product coded BFN2022-06. Plant Health Care, a UK-listed biologicals company that has held Brazilian regulatory approvals since at least 2023, had an entry for PHC 68949 WP. A fifth company, Cropchem, received crop-inclusion evaluations for two existing formulated products, Chust 250 CS and Taura 200 EC, extending their approved use to additional crops.

This batch is worth tracking because it shows a multinational originator, Syngenta, expanding its Brazilian biological fungicide line at the same time as smaller specialist and foreign-partnered firms move through the same regulatory stage. Brazil has positioned itself as one of the fastest-growing biological crop protection markets globally, and this kind of post-registration label expansion, adding crops and pests to products already sold, is typically how companies grow revenue from an existing biological asset without the cost of a brand-new registration. For global suppliers weighing where to invest in biologicals manufacturing or registration capacity, a multinational actively broadening an existing biofungicide portfolio in Brazil, alongside FMC’s local biologicals partner and a London-listed specialist, is a reasonable signal that the registration pathway for biologicals in Brazil, while still slower than most companies would like, is functioning well enough to support incremental label growth.
