Abstract

The invention provides an environment-friendly dinotefuran microemulsion which is prepared from the following components in percentage by weight: 1 to 20 percent of dinotefuran , 4 to 10 percent of anionic surface active agent, 2 to 12 percent of non-ionic surface active agent, 5 to 12 percent of ketone solvents with a boiling point above 150 DEG C, 0.01 to 0.04 percent of defoaming agent, and the balance of water, wherein the anionic surface active agent is selected from one or more of anionic surface active agents, wherein the hydrophobic group of the anionic surface active agents is vegetable oil hydrolyzed or pyrolysed linear chain alkyl or alkenyl, and the hydrophilic group of the anionic surface active agents is selected from carboxyl, acidophobe or sulfonic acid group; the non-ionic surface active agent is selected from one or more of polyethoxylated non-ionic surface active agents, wherein the hydrophobic group of the non-ionic surface active agent is vegetable oil or vegetable oil hydrolyzed or pyrolysed linear chain alkyl or alkenyl. The invention also provides a preparation method of the environment-friendly dinotefuran microemulsion.

Description

technical field [0001] The invention belongs to the field of new formulations of pesticides, in particular to a new environmentally friendly dinotefuran microemulsion using a plant-derived emulsifier and a preparation method thereof. Background technique [0002] Pesticides (referring to pesticide preparations in this specification) are special commodities for controlling agricultural and forestry crop diseases, insects, and weeds, and are indispensable means of production for modern agriculture. But it is also a "double-edged sword". On the one hand, through the application of pesticides, the country can recover about 30 billion kilograms of grain loss every year. On the other hand, the resulting food safety and environmental pollution problems are becoming increasingly prominent. The pollution caused by pesticides is caused by the active ingredients themselves, as well as by the solvents and auxiliaries in the formulation. Since the amount of solvents and additives is ge...
