German startup SenseUP is enhancing RNA interference biopesticides to address agricultural pests more efficiently while lowering environmental impacts.
RNA interference (RNAi) presents a unique opportunity in pest management by targeting specific genes in pests and pathogens without negatively impacting surrounding soil, plants, or wildlife. This precision offers a stark contrast to traditional chemical pesticides, which often include broader applications that can harm non-target species and ecosystems. Yet, achieving stability, cost-efficiency, and versatility presents significant hurdles that SenseUP is determined to address.
Addressing Key Challenges in RNAi Implementation
According to Juan Martinez, co-CEO and managing director of SenseUP, the startup is tackling three primary challenges that have historically hampered the widespread adoption of RNAi products: stability, cost, and the ability to target multiple pests simultaneously.
Stability: RNA molecules are inherently unstable; they can degrade quickly, especially in variable field conditions. SenseUP addresses this issue by encapsulating double-stranded RNA (dsRNA) within the cell walls of tailored strains of Corynebacterium. This innovative method allows these RNA-based biopesticides to remain stable for over 18 months at room temperature, which makes storage and transportation significantly easier.
Cost: In addressing production costs, SenseUP utilizes biosensors to identify high-yielding strains of Corynebacterium. This approach enables screening of millions of strains efficiently, allowing the company to identify the most suitable candidates for commercial biopesticide production that can compete price-wise with traditional synthetic options.
Breadth of Application: SenseUP's technology also combines multiple dsRNA sequences into one formulation, providing a single biopesticide capable of targeting various pests simultaneously. This flexibility is particularly appealing to farmers who prefer comprehensive solutions over multiple products.
From Niche to Mainstream
Martinez suggests that the perception of RNAi's role in crop protection has shifted. “A few years ago, I would have said that RNAi would remain a niche market; today, I believe it will become mainstream,” he remarked during a recent interview at the World Agri-Tech Innovation Summit in London. The shift in perspective reflects growing confidence in the technology's potential as well as advancements in regulatory pathways.
The Scope of SenseUP's Technological Advancements
SenseUP differentiates itself from other companies in the RNAi space by not limiting its focus to just insecticides. The startup is also observing promising results in developing fungicides. Their platform aims to create a wide array of solutions for both crop protection and animal health.
On their business model, Martinez clarifies that while SenseUP will handle technology development and manufacturing, the commercialization aspect will involve partnerships with established crop protection companies. This structure allows SenseUP to concentrate on leveraging its expertise while relying on partners for marketing and distribution.
Partnerships and Regulatory Pathways
Understanding what larger crop protection companies seek before committing to partnerships is essential. Martinez highlights that they typically look for evidence of efficacy from field trials, consistent product performance, scalability of production, and a clear regulatory pathway.
SenseUP claims to have made significant progress in all these areas. Their biopesticide has shown strong performance in trials, maintaining stability and cost-effectiveness while also being scalable for larger production needs. Additionally, the burgeoning acceptance of RNAi products within regulatory frameworks is promising. Recently, various products have received approvals in markets, including rapid registrations in the U.S. and even more impressively, in Mexico.
Furthermore, with ongoing legislative adjustments in the European Union aimed at streamlining the approval processes for agricultural biologicals, there’s optimism that new RNAi products will be recognized and integrated into existing agricultural policies.
Initial Focus and Future Directions
In terms of practical applications, SenseUP has directed its initial research towards controlling *Coleoptera* (beetles) and various sucking pests. The company is also exploring fungicides that would impact crops such as grapes and potatoes, signaling a broad approach to agricultural pests and diseases.
Martinez believes that once RNAi products prove effective in higher-value crops, they will likely expand to address common challenges faced by a wider range of agricultural sectors, including broad-acre crops. The evolution from niche solutions to mainstream applications may also draw in sectors unfamiliar with biological solutions, ultimately benefiting agricultural ecosystems.
Conclusion
As agriculture continues to navigate the challenges of sustainability and productivity, the advancements made by SenseUP offer a glimpse into a potential future where crop protection is both environmentally responsible and economically viable. With ongoing improvements in technology and growing regulatory support, RNA interference may indeed transition from a niche technology to a staple in modern agriculture.
