In 1950, a new DDT workshop was built in the Sichuan Luzhou Chemical Plant. The 666 developed by the North China Institute of Agricultural Sciences and the Shanghai Pest and Insect Medicine Factory was also put into production in 1951. After that, toxaphene developed by the Zhejiang Chemical Research Institute was put into production in Zhejiang, Fujian, Anhui and other provinces. In 1952, 666, which was researched and developed by Shenyang Chemical, was also put into production in Shenyang; the production of 666 developed rapidly in my country, and the highest annual output reached 350,000 tons in the 1970s.
