Agricultural Biologicals: RNA and Biocontrol Enter a New Technology Race from the U.S. to Brazil
RNA bioinsecticides, bacteriophages and microbial solutions are advancing as the U.S. and Brazil emerge as key testing grounds for biologicals.
On September 17, 2026, AgroSpheres and FMC announced that two proprietary RNA-based bioinsecticide candidates had advanced into global field development across the United States, Brazil and Asia, following laboratory, greenhouse and research-plot evaluations. The milestone matters because it moves a new class of precision biological crop protection closer to commercial agriculture while targeting economically important lepidopteran pests, including fall armyworm (Spodoptera frugiperda). For growers across the Americas, the trials could help determine whether RNA technologies can deliver reliable performance under real-world production conditions.
The candidates combine proprietary RNA biomolecules with AgroSpheres' AgriCell delivery technology, designed to protect and efficiently deliver biological active ingredients. The critical test now moves from proof of concept toward field consistency, scalability and economics. Those factors will ultimately matter more to growers than the "biological" label itself. Performance across different environments, residual activity, application requirements, compatibility with integrated pest management programs and cost per acre will be central to determining whether these technologies can compete alongside established chemical and biological crop protection tools.
Fall armyworm (Spodoptera frugiperda) is among the economically important lepidopteran pests targeted by emerging RNA-based bioinsecticide technologies.
From RNA to Bacteriophages, Biological Crop Protection Expands
RNA is only one part of a broader technology shift. In the United States, EcoPhage received U.S. Environmental Protection Agency approval for GoldenEco, a bacteriophage-based biopesticide designed to control bacterial diseases caused by Xanthomonas and Pseudomonas in tomatoes and peppers. Bacteriophages are naturally occurring viruses that infect specific bacteria, providing a highly targeted biological approach that differs significantly from conventional chemical or copper-based disease-control strategies.
The development illustrates how quickly the definition of agricultural biologicals is expanding beyond traditional inoculants, microbial products and biostimulants. The pipeline now includes bacteriophages, RNA molecules, engineered microbes, nitrogen-fixing technologies and next-generation biofungicides. For U.S. agriculture, the opportunity is tied not only to sustainability goals but also to resistance management, production efficiency and the need for additional modes of action. Yet biological origin alone does not guarantee commercial success: efficacy, shelf life, formulation, logistics and return on investment remain essential.
Investment by major crop protection companies reinforces that shift. Syngenta, for example, is expanding biological research within its global Seedcare network, while its agreement with Amoéba provides exclusive distribution rights for a next-generation biofungicide targeting Septoria leaf blotch and yellow rust in European cereal markets. The significance for the U.S. is strategic rather than immediate commercial availability: biological technologies are increasingly being incorporated into mainstream R&D portfolios rather than developed as a separate niche within crop protection.
Agricultural biologicals are expanding beyond conventional microbial products to include RNA molecules, bacteriophages and other precision biotechnology platforms.
Brazil, meanwhile, provides a particularly important testing ground. Its enormous corn and soybean acreage, tropical and subtropical pest pressure, multiple cropping cycles and sophisticated commercial farming sector make the country a demanding environment for new crop protection technologies. Including both the United States and Brazil in RNA bioinsecticide field development allows developers to evaluate performance across two of the world's most important agricultural markets, while generating data under markedly different production systems and environmental conditions.
U.S.-Brazil Agriculture Could Shape the Next Biologicals Market
Brazil's role extends beyond field trials. The country established a dedicated legal framework for bioinputs through Law 15,070/2024, covering production, registration, import, export, research, commercialization and agricultural use. In 2026, Brazilian authorities continued working on implementation of the framework. Regulatory clarity is becoming a competitive factor in agricultural biotechnology, because the speed and predictability of registration can influence where companies conduct trials, deploy capital and prioritize commercial launches.
The U.S. brings another essential component: an established regulatory pathway for microbial and biochemical pesticides through the EPA, combined with one of the world's largest crop protection markets and a deep agricultural biotechnology ecosystem. For developers, however, regulatory approval represents only one hurdle. The transition from successful trials to repeat grower adoption requires dependable field efficacy and a clear economic proposition. Biological products must fit existing equipment, application windows and integrated pest management systems without introducing complexity that outweighs their agronomic benefits.
Brazil's production scale, multiple cropping systems and intense pest pressure make the country a strategic testing ground for next-generation biological crop protection.
There is also a trade dimension. U.S. and Latin American agricultural value chains increasingly operate within markets shaped by maximum residue limits, phytosanitary standards, traceability requirements and sustainability commitments. Biological crop protection could provide additional tools for meeting some of those demands, particularly in high-value export crops. At the same time, differences between regulatory systems can become non-tariff barriers when products, active ingredients or residue standards recognized in one market are treated differently in another.
The emergence of RNA bioinsecticides therefore represents more than another product launch. Crop protection is moving toward a portfolio where chemistry, biology, biotechnology and digital agriculture increasingly coexist. The U.S. brings regulatory capacity, investment and a powerful innovation ecosystem; Brazil contributes agricultural scale, intense pest pressure and one of the world's most dynamic tropical production systems. How technologies perform across both markets could provide an early indication of whether the next generation of biologicals can move from promising science to practical, scalable tools for farmers across the Americas.
