As of December 31, 2018, the use of endosulfan and methyl bromide, the two high-toxic pesticides, will be prohibited in China for agricultural purposes.
Methyl bromide is a colorless and odorless gas. With its high efficiency and broad spectrum, the product can exterminate a large variety of insect pests. Since the 90s, governments of all countries stopped the use of this fumigant. In China, from July 1, 2018, the registration of methyl bromide was revoked, followed by the prohibition of the use of methyl bromide for agricultural purposes as of December 31, 2018.
At present, China has three methyl bromide technical enterprises and only one formulation product. In the United States, methyl bromide is used for pre-planting soil fumigation, harvesting fumigation and architectural fumigation. In the EU, it was banned in 2008. In Australia, it is only used for soil fumigation.
Endosulfan is an insecticidal and miticidal agent with contact toxicity and stomach toxicity, which is not systemic. As an organochlorine compound, it has a bioaccumulation and endocrine disruption effect. Since July 1, 2018, the registration of endosulfan was revoked in China. From March 27, 2019, the use of all endosulfan products for agricultural purposes will be prohibited.
Endosulfan has been banned in more than 50 countries, including the EU, some Asian and West African countries. However, it is still in use in quite a lot of countries, including India, Brazil and Australia. Since March 31, 2016, the registration of endosulfan was revoked in the US. In the EU, it was banned in 2005.
