The Rotterdam Convention was officially in force in China in January. The reporter interviewed several pesticide manufacturers. The relevant personnel of these enterprises all stated that they are taking measures to stop the production of highly toxic products and implement low-toxicity reforms to speed up the adjustment of pesticide structure.
Li Ke, chief of the Department of Foreign Economics of Jiangsu Lianyungang Liben Pesticide Co., Ltd., told reporters that after the implementation of the Rotterdam Convention, importing countries will surely restrict the products with high toxic content and the demand will also decrease. The toxic products have taken measures to reduce production and stop production. At the same time, because the market has a greater demand for herbicides and a broader market than pesticides, they will also develop herbicides.
Liu Fujun, manager of the technical department of Shandong Huayang Pesticide Chemical Industry Group, said in an interview that they currently have more than 20 original drugs and more than 100 dosage forms, but there are more highly toxic varieties. At present, they are gradually implementing low-toxicity reforms in a planned manner. The first is to improve the process and use phosgene resources to transform existing high-toxic pesticide products to reduce their toxicity. For example, the original aldicarb was converted to oxapropionate, which greatly reduced the toxicity of the product; the conversion of carbofuran to butylthiocarbamate reduced the toxicity of the drug; the sulphur double produced after the modification of methomyl was modified. Wei, the toxicity of the product is also greatly reduced. The second is to improve the dosage form. Drawing on the successful experience of foreign countries, they gradually improved some of the traditional pesticide formulations such as powders, wettable powders, and emulsifiable concentrates, eliminated a number of backward formulations with serious environmental pollution, and developed a batch of environmentally friendly new pesticide formulations such as suspension concentrates, Water emulsions, soluble granules, etc. achieve efficient and safe use.
