The Institute for the Control of Agrochemicals, Ministry of Agriculture (ICAMA) was established in 1963 as an institution affiliated with the Ministry of Agriculture (MOA). ICAMA, as mandated by MOA, specializes in nation wide pesticide registration and administration with the main responsibilities for registration, quality control, bioassay and residue monitoring of pesticides, supervision of pesticide markets, information-sharing, international cooperation and other services. You may visit the website http://www.chinapesticide.org.cn/. 
We have managed to reprocess the registration data(till 2021.12) as per the Chinese version of the website and list below the TOP100 companies that holding the most registrations of technical materials in China. As we couldnot find/match the English name of each company, there could be some differences in presenting the exact English names as they should be. Please let us know if you have any doubts. If you need the full list, please mail us sales@vcommend.com.
