Nissan Chemical and BASF form strategic partnership to bring BASF’s novel insecticide, Prexio® Active, to rice growers in Japan

October 17, 2025

Nissan Chemical Corporation (Headquator: Tokyo Japan, Representative Director, President: YAGI Shinsuke) and BASF today announced a strategic partnership to develop and commercialize BASF's innovative insecticide active ingredient, Prexio®Active, for rice growers in Japan.

Prexio® Active (active ingredient: Fenmezoditiaz, Development code: NC-520) delivers exceptional, long-lasting control of key rice pests, including rice planthoppers, green rice leafhopper, and chewing insect pests such as rice water weevil, rice leaf beetle, rice stem borer, and rice skipper.

"This collaboration reflects our commitment to supporting sustainable growth of Japanese agriculture with locally relevant innovations," said Yuji Sato, Head of Agricultural Chemicals Division at Nissan Chemical Corporation. "Prexio® Active provides growers with a new option to manage pest resistance and improve productivity in rice."

"Prexio® Active is the result of years of targeted research into effective and sustainable pest control," said Harold Bastiaans, Vice President Global Insecticide Research and Seed Solutions at BASF Agricultural Solutions. "With Prexio® Active, we can safeguard rice while limiting the effect on non-target species when applied according to label instructions."

"Prexio® Active helps effectively manage most of the key pests in rice and offers great operational flexibility, allowing growers to readily adapt it to various rice farming practices that support sustainable rice production in Japan," said Stephanie Jensen, Vice President Crop System Rice and Portfolio Solutions Insecticides and Seed Treatment at BASF Agricultural Solutions. "Designed for flexibility and ease of use, Prexio® Active supports a wide range of rice farming practices, including granular application for traditional nursery box farming and foliar application for both transplanted and direct-seeded rice."

Through this partnership, BASF and Nissan will each develop tailored formulations and mixtures with Prexio® Active, which will be offered to rice growers in Japan.
