Brazil officially imposes ban on paraquat from September 22 10-15-2020

According to the Collegiate Directorship Resolution (RDC) 177/2017, the Brazilian National Health Surveillance Agency (Anvisa) maintained the decision to ban paraquat by a vote of three to two on September 15, which took effect on September 22. That means, paraquat will not be produced or used in Brazil, and the import of paraquat to Brazil will be prohibited.

In 2008, Anvisa began reassessment of 14 agrochemical active ingredients including paraquat, and later in October, 2017 announced the Collegiate Directorship Resolution (RDC) 177/2017, which imposed a complete ban on paraquat starting September 22, 2020. The 3 years before the ban took effect were a transitional period intended to allow enterprises to gradually curtail their use of parquat. The decision was made because paraquat is connected with an increased risk of Parkinson's disease and has a potential mutagenic effect on cells.

Ministry of Agriculture and Rural Affairs of China increases regulation of paraquat


On October 9, 2020, the Ministry of Agriculture and Rural Affairs of China published a notice of increased regulation of paraquat on its official website. The new regulation will require stricter rules for the production and export of paraquat. According to the notice, only enterprises with a production license of paraquat technical concentrates and a registration certificate for exports are allowed to produce paraquat technical concentrates in China. Paraquat manufacturers should apply for official verification of proper qualifications for the production of paraquat technical concentrate by November 11, 2020. In addition, manufacturers of paraquat technical concentrates will no longer sell paraquat products inside China, and paraquat products should only be allowed for export.

The notice also mentions an increase in national supervision and spot-checks on other pesticides including aquacid, glyphosate as well as glufosinate, to make sure that no additional paraquat is added into these pesticides.


In 1984, paraquat was first introduced into the Chinese pesticide market. During that time, paraquat was practical but expensive in China. The principal of Shandong Academy of Pesticide Sciences started to do research and development on paraquat afterward, and finally successfully developed technology for paraquat production in 2004. China became the second country to develop paraquat technology and the largest producer for paraquat, and since then paraquat was widely used across China.

Glufosinate industry expected to flourish in China as paraquat faces stricter regulations

Besides glyphosate and glufosinate, paraquat, which is being used in over 120 countries, is the third most common non-selective pesticide in the world. Recently, due safety concerns regarding paraquat, the use of glufosinate in China and other Southeast Asian countries has become more common. As a result, glufosinate has become the second most popular non-selective pesticide in the world in 2018. The current prohibition on the use of paraquat in Brazil has left room for other pesticides in the market. China is also the largest producer of glufosinate in the world. With Brazil’s ban on the production and usage of paraquat products, imports of glufosinate from China are expected to increase.

Lier Chemical, Seven Continent and Limin Group Co., Ltd. are the three largest glufosinate manufacturers in China. Among the three manufactuers, Lier Chemical is the largest glufosinate manufacturer in the world. Its production bases in Mianyang and Guangan cities can produce approximately 17,000 tons glufosinate per year.
