At least 74 countries do not authorise paraquat in their markets, with bans, phase-outs, and withdrawals from the market. National and regional bans and phase-outs were effective at reducing paraquat poisoning and deaths. Restrictions on the use and application of paraquat, however, did not always result in a significant reduction in poisoning or suicide mortality, and many countries introduced bans after restrictions proved ineffective.

European countries were the first to ban paraquat due to its high acute toxicity, irreversible toxic effects, and risk of unintentional poisoning (Norway (1981), Sweden (1983), Hungary (1991), Austria (1993), Denmark (1995), and Finland3 (1996)) [73]. A regional-level European Union (EU) wide ban on paraquat applicable to all 27 member countries in 2007
In Brazil, in 2015, the National Health Surveillance Agency (ANVISA) concluded that paraquat should be banned due to the high incidence of acute poisoning and the association with Parkinson's disease [41, 74]. In 2017, the Collegiate Directorship Resolution 177/2017 imposed a complete ban on paraquat starting in 2020 [75]. The preceding three years were a phase-out period to allow businesses to gradually stop paraquat use [3, 40].
China, the largest paraquat producer in the world, announced its intention to ban paraquat in 2012 due to its chronic toxicity and adverse health events, including suicides. In 2014, the government stopped registration and licensing of the liquid solutions of paraquat; all domestic sales and use of paraquat stopped in 2016. A paraquat gel product was registered in 2016 and withdrawn in 2020. The production of paraquat for export purposes is still allowed [76].
