Syngenta Unveils MicroRNA Platform Yielding 5-10% Crop Gains

Syngenta has introduced a new agricultural platform called EXORT that uses naturally occurring plant microRNAs to increase crop yields by 5% to 10%. Rather than altering a plant's DNA or applying synthetic chemicals to kill pests, the technology sprays tiny doses of natural regulatory molecules directly onto leaves to optimize how the plant allocates its own resources for grain and fruit growth. This approach marks a departure from conventional agrochemicals, focusing instead on influencing the crop's internal biological processes to maximize its natural potential.[1][2]

The fundamental mechanism relies on microRNAs, which act as biological "dimmer switches" within plant cells. These tiny molecules naturally regulate how genetic instructions are translated into proteins. By applying a precisely selected pool of plant-derived microRNAs, the EXORT platform fine-tunes the plant's existing biological signaling mechanisms. When sprayed onto the leaves, the microRNAs are absorbed and temporarily influence gene expression to prioritize fruit set, grain growth, and overall development. Because the platform uses the plant's pre-existing regulatory pathways, it does not introduce new genetic material or permanently alter the organism's underlying DNA sequence.[2][6]

The platform's efficacy was tested in 240 field trials across more than 15 countries between 2022 and 2025. Across six major crops—including rice, soybean, corn, cotton, fruits, and vegetables—the microRNA application consistently delivered yield improvements ranging from 5% to 10% compared to untreated crops. In specific rice trials, yields increased by as much as 740 kilograms per hectare. The extensive testing program, described as one of the largest biological field programs of its kind, demonstrated that the fundamental biological mechanism could be reliably translated into a practical, field-scale agricultural solution.[5][6]

Because the plant's own biological processes amplify the initial microRNA signal, the required dosage is exceptionally low. Approximately 50 milligrams of the active compound are delivered in about 100 grams of formulated product per hectare. This allows the treatment to be incorporated into existing tank mixes, meaning farmers do not need to alter their standard field routines, purchase new application equipment, or change their established crop management schedules. The ability to integrate seamlessly into current farming practices removes a significant barrier to widespread commercial adoption.[3][5][6]

The ultra-low application rate also presents significant logistical and environmental advantages. A single pallet of the EXORT-based product can treat roughly 15 times as many hectares as a standard liquid biostimulant. This translates to an estimated 99% reduction in plastic packaging and a 90% decrease in required warehouse storage volume per hectare. For large-scale agricultural operations, these reductions in shipping weight and storage space represent substantial cost savings and a lower carbon footprint across the supply chain.[5][6]

Syngenta describes the platform as a fundamental shift in agricultural science and crop protection. Jerome Cassayre, Syngenta's head of biologicals research, stated, "EXORT technology introduces a new class of active substances and is the first novel mode of action in biologicals in more than 20 years." The company plans to launch the first commercial products in Latin America in 2027. Following that initial rollout, a phased introduction is scheduled across approximately 20 countries, pending the establishment of regional regulatory frameworks for agricultural biostimulants.[6]

While the field trials show consistent gains, the technology's performance remains sensitive to environmental conditions. Syngenta's data indicates that the microRNAs work best when applied to actively growing leaves under favorable water-uptake conditions. Corn responded most strongly under higher rainfall and humidity, while tomatoes showed the best results under moderate-to-low fertility stress. These variations indicate that the platform's success will depend heavily on precise application timing and local climate factors, requiring farmers to carefully monitor field conditions to maximize the biological response.[5]

The transition from fundamental microRNA research to a field-scale agricultural tool marks a significant shift in crop management strategy. As the 2027 commercial launch approaches, the agricultural sector will watch closely to see if these biological signals can reliably maintain their 5% to 10% yield gains across the unpredictable variables of global commercial farming. If successful, the platform could open a new category of biological agricultural inputs focused entirely on influencing a plant's own regulatory systems rather than supplying conventional nutrients or combating external pathogens.[1][2][6]
