Syngenta and Kyoyu Agri Join Forces to Develop an Innovative Rice Herbicide
Syngenta, a global leader in agricultural innovation and crop protection, has announced a strategic collaboration with Kyoyu Agri Co. Ltd., a leading Japanese agrochemical manufacturer, to expand access to advanced herbicide solutions for rice farmers across selected Asian markets. The partnership will focus on products based on Cyclopyranil, a novel herbicide active ingredient developed by Kyoyu Agri, with the aim of addressing the growing challenge of herbicide-resistant weeds and supporting sustainable rice production.
The collaboration represents an important step toward providing rice farmers with innovative weed management technologies at a time when resistance to existing herbicides is becoming an increasingly serious concern. By combining Kyoyu Agri’s proprietary technology with Syngenta’s extensive commercial reach and distribution network, the companies aim to make advanced crop protection solutions more accessible to farmers in key rice-producing regions of Asia.
Cyclopyranil Offers a New Approach to Rice Weed Management
Cyclopyranil is a novel herbicide active ingredient designed to provide effective control of a broad range of troublesome weeds in rice cultivation. Its ability to deliver high levels of weed control at low application rates makes it a promising addition to existing weed management programs. The technology is expected to provide farmers with another tool for protecting their crops against weeds that compete with rice plants for essential resources such as nutrients, water, sunlight, and space.
One of the key features of Cyclopyranil is its unique mode of action. It is the first rice herbicide in Syngenta’s portfolio to be based on the protoporphyrinogen oxidase (PPO)-inhibiting mode of action, classified under Herbicide Group 14. This mechanism offers a different approach to weed control compared with several commonly used herbicide groups.
The introduction of a new mode of action is particularly significant as agricultural producers face increasing difficulties in managing weed populations that have developed resistance to established herbicides. Cyclopyranil can control a wide spectrum of broadleaf and grass weeds through contact activity, including certain weed populations that have developed resistance to herbicides with other modes of action, such as acetyl-CoA carboxylase (ACCase) and acetolactate synthase (ALS) inhibitors.
Another important advantage of Cyclopyranil is its flexibility of application. It can be used as either a pre-emergent or post-emergent herbicide, depending on the product formulation, approved label directions, and the specific weed management requirements. This flexibility can help farmers adapt their weed control programs to different field conditions and crop growth stages.
Addressing the Growing Challenge of Herbicide Resistance
Herbicide resistance has emerged as one of the major challenges confronting rice farmers worldwide. The repeated use of herbicides with the same mode of action can create selection pressure, allowing resistant weeds to survive and reproduce over successive growing seasons. As these populations spread, the effectiveness of conventional weed control methods can decline, increasing the difficulty and cost of protecting rice crops.
Researchers have documented more than 190 cases of herbicide-resistant weeds in rice production systems globally. These cases highlight the need for diversified weed management strategies and the development of new crop protection technologies that can help farmers respond to evolving weed populations.
Among the most problematic weeds in rice cultivation is barnyard grass (Echinochloa crus-galli). This aggressive weed competes with rice plants for essential nutrients, water, and other resources, potentially reducing crop growth and productivity. Its close resemblance to young rice plants can also make early identification difficult, allowing infestations to become established before effective control measures are implemented.
The spread of resistant barnyard grass and other troublesome weeds can place considerable pressure on rice production systems. Farmers may need to invest additional time and resources in weed control, while inadequate management can threaten crop yields and profitability.
Against this background, the introduction of Cyclopyranil-based herbicide solutions could help broaden the range of weed control options available to rice growers. When integrated into an appropriate resistance management program, herbicides with different modes of action can contribute to more diversified weed control strategies. Effective resistance management also depends on following product labels, rotating or combining suitable modes of action where recommended, and incorporating cultural and mechanical weed control practices.
Syngenta Highlights Its Commitment to Agricultural Innovation
Commenting on the partnership, Ioana Tudor, Global Head of Marketing at Syngenta Crop Protection, emphasized the importance of developing new solutions as herbicide resistance continues to spread.
She noted that rice farmers are facing a shrinking range of effective weed control options as resistant weed populations become more widespread. According to Tudor, Syngenta is committed to reversing this trend by introducing the next generation of innovative crop protection technologies.
She added that the collaboration with Kyoyu Agri would provide farmers with new tools to address herbicide resistance, protect their yields, and support the long-term productivity of rice farming.
Syngenta’s participation in the agreement reflects its broader focus on providing crop protection solutions that respond to changing agricultural challenges. By working with technology developers and agrochemical manufacturers, the company aims to expand the availability of innovative products that can help farmers manage weeds more effectively and maintain agricultural productivity.
Kyoyu Agri Seeks to Expand the Global Reach of Its Technology
Masakazu Yamada, President of Kyoyu Agri, described the agreement as a significant milestone in bringing the company’s proprietary technologies to international markets.
Yamada expressed confidence that Syngenta’s established distribution network would help make the Cyclopyranil-based innovation available to rice farmers across selected Asian countries. He also highlighted the importance of helping farmers overcome the growing problem of weed resistance, protect their harvests, and reduce the operational burden associated with daily farm management.
For Kyoyu Agri, the collaboration offers an opportunity to extend the reach of its research and development capabilities beyond its existing markets. Partnering with a global crop protection company could help accelerate the commercial introduction of its technology in regions where rice cultivation plays a major role in food production and agricultural livelihoods.
The agreement also demonstrates the importance of collaboration between agrochemical innovators and international crop protection companies in responding to complex agricultural challenges. Developing a new active ingredient is only one part of the process; bringing it to farmers also requires regulatory approvals, product development, distribution capabilities, and appropriate technical support.
Expanding Access to Advanced Herbicide Solutions Across Asia
Under the agreement, Syngenta will market products based on Cyclopyranil in a number of Asian countries. The partnership is expected to strengthen the range of weed management options available to rice farmers in selected markets, although the timing of product launches and availability will depend on local regulatory approvals and market-specific requirements.
Asia is a particularly important region for rice production, with millions of farmers depending on the crop for their livelihoods and communities relying on it as a staple food. Effective weed management is essential to maintaining crop productivity, improving resource use, and reducing avoidable yield losses.
The introduction of Cyclopyranil-based products could provide an additional option for farmers dealing with difficult-to-control weeds, particularly where resistance has reduced the effectiveness of existing herbicides. Its low-rate activity, broad weed control spectrum, and flexible application timing may offer practical benefits when products are used according to approved recommendations.
However, the long-term effectiveness of any herbicide depends on responsible use. Integrating new technologies into comprehensive weed management programs will be important to help preserve their performance and limit the further development of resistance.
A Strategic Step Toward the Future of Rice Farming
The collaboration between Syngenta and Kyoyu Agri marks a significant development in the effort to address herbicide resistance in rice cultivation. By combining Kyoyu Agri’s Cyclopyranil technology with Syngenta’s global expertise and distribution capabilities, the companies aim to expand access to innovative weed control solutions in selected Asian markets.
As resistant weeds continue to challenge conventional agricultural practices, the development of new herbicide technologies and diversified weed management approaches will remain essential. The partnership reflects a shared commitment to helping farmers protect crop yields, manage increasingly complex weed populations, and improve the efficiency of their farming operations.
With Cyclopyranil-based solutions planned for introduction across selected Asian countries, the collaboration could contribute to strengthening weed management programs and supporting the future productivity of rice farming. The success of this effort will depend on regulatory progress, responsible product use, and the integration of the new technology into broader, sustainable agricultural practices.
