en.Wedoany.com Reported - Lier Chemical Co., Ltd. (002258.SZ), a Chinese pesticide manufacturer, plans to construct a relocation project for a fine chemical multi-functional pilot verification platform in a new plant area located in Hongwu Village, Tangxun Town, Mianyang Economic and Technological Development Zone, Sichuan Province. The project has a total investment of 35 million yuan, including 2.09 million yuan for environmental protection, and will build three new pilot production lines with a pilot period not exceeding two years. The maximum pilot scale for pyroxasulfone, methoxyfenozide, and cyantraniliprole is 50 tons per year each.
Lier Chemical Co., Ltd., founded in 1993 and headquartered in Mianyang City, Sichuan Province, was listed on the Shenzhen Stock Exchange in July 2008. The company is primarily engaged in the research, development, production, and sales of high-efficiency and safe pesticides, with products covering three major series: herbicides, insecticides, and fungicides, including over 30 technical materials, more than 100 formulation varieties, and some chemical intermediates. The company has production bases in Mianyang (Sichuan), Nantong (Jiangsu), Guang'an (Sichuan), Yueyang (Hunan), Hebi (Henan), Jingzhou (Hubei), and Jinshi (Hunan).
According to the developer's plan, the original pilot project ("New Pesticide Pilot Research and Engineering Verification Project") at the old plant site is scheduled to cease pilot operations in June 2026, and the pilot production line for cyantraniliprole has not yet been constructed. This relocation project will build a new fine chemical multi-functional pilot workshop in the new plant area, covering an area of approximately 1,200 square meters. The workshop will be equipped with reactors, quenching tanks, quenching crystallization tanks, cooling crystallization tanks, neutralization and phase separation tanks, centrifuges, dryers, solvent recovery tanks, solvent distillation tanks, distillation column kettles, and various intermediate storage tanks, along with supporting storage, transportation, utility, and environmental protection facilities.
The three products planned for pilot testing are all new high-efficiency varieties currently attracting significant attention in the pesticide industry. Pyroxasulfone is a novel isoxazole herbicide primarily used for pre-emergence soil treatment in crops such as corn and soybeans; methoxyfenozide is an insect growth regulator insecticide that disrupts the normal molting process of pests by mimicking the action of molting hormone; cyantraniliprole is a diamide insecticide developed by DuPont, belonging to the same class as chlorantraniliprole, characterized by high efficacy and a broad spectrum. If this pilot project is successfully implemented, it will provide process verification data to support the subsequent industrial scale-up of these products. The project is currently in the public notice stage for the proposed approval of its environmental impact assessment.
