Syngenta has entered a strategic collaboration with Kyoyu Agri Co. Ltd to bring a new rice herbicide based on the active ingredient Cyclopyranil to selected markets across Asia, underscoring the company’s continued appetite for external innovation.
The agreement will see Syngenta market products based on Cyclopyranil, a novel herbicide active ingredient developed by the Japanese agrochemical manufacturer, leveraging its own regulatory expertise, manufacturing capabilities and commercial network to scale the technology across key rice-growing regions.
External innovation strategy on show
The partnership is notable at a time when Syngenta has been linked with plans for a future Hong Kong IPO, with investors likely to scrutinise how the company balances investment in internal research with access to innovation from external sources.
Rather than bearing the full cost and risk of discovering new active ingredients itself, the deal demonstrates how major crop protection companies can complement their own R&D efforts by commercialising technologies developed by smaller specialist innovators.
New tool against resistant weeds
Cyclopyranil is Syngenta’s first rice herbicide based on the protoporphyrinogen oxidase (PPO)-inhibiting mode of action, also known as Herbicide Group 14. According to the companies, the active ingredient delivers effective control of a broad spectrum of grass and broadleaf weeds, including populations that have developed resistance to widely used ACCase and ALS herbicides.
The herbicide can be used both before and after weed emergence, providing growers with greater flexibility in management programmes.
The launch comes as herbicide resistance continues to spread in rice production systems. Researchers have documented more than 190 cases of herbicide-resistant weeds in rice globally, with species such as barnyard grass posing a growing threat to yields.
“As herbicide resistance spreads, the effective toolbox of options available to rice farmers is steadily dwindling,” said Ioana Tudor, Global Head of Marketing at Syngenta Crop Protection. “Our collaboration with Kyoyu Agri will bring farmers new breakthrough tools to overcome resistance, protect their yields, and ensure a productive future for rice farming.”
Route to market
For Kyoyu Agri, the deal provides access to markets that would be difficult to reach alone.
“Bringing our proprietary technologies to the global stage is a key milestone for us,” said Masakazu Yamada, president of Kyoyu Agri, who said Syngenta’s distribution network would help make the technology widely available across Asia.
The collaboration illustrates how large agribusinesses look to be increasingly acting as commercialisation partners for externally developed technologies, combining discovery from specialist innovators with the scale needed to bring new crop protection tools to farmers worldwide.
