Overseas agrochemical giants halt paraquat production? Hongli Direct line-up limit up in afternoon, company responds

On the afternoon of March 4th, the leading pesticide company Hongtaiyang’s stock price surged straight to the daily limit. As of 2:07 PM, it was trading at 6.83 yuan per share, with over 380,000 lots of buy orders on the limit-up board, driving the collective activity of pesticide concept stocks such as Guangkang Biochemical, BSM, and Zhongqi Shares. According to industry website World Agrochemical Network this morning, Syngenta will cease all global production of paraquat herbicide by the end of June 2026. This move is due to fierce competition from global generic drug manufacturers, gradually weakening Syngenta’s production advantage in this field. Regarding the stock price movement, a reporter from 21st Century Business Herald contacted Hongtaiyang as an investor. Company staff responded that the afternoon price increase may be directly related to the news of Syngenta’s production halt. Hongtaiyang’s global market share of paraquat exceeds 50%. Currently, only Syngenta has large-scale overseas capacity, and after its shutdown, global capacity will further concentrate domestically. Regarding market concerns about price increases, the company stated that the event was sudden, and it has not yet determined whether paraquat prices will rise. The specific impact on performance is still under assessment. (21st Century Business Herald)
