Abstract

The invention discloses an emamectin benzoate suspending agent and a preparation method thereof. The emamectin benzoate suspending agent comprises the following components by weight percent: 0.2-5 percent of emamectin benzoate, 1-10 percent of wetting dispersant, 2-10 percent of antifreeze agent, 1-6 percent of stabilizing agent, 1-5 percent of defoamer, 0.1-1 percent of thickening agent, 0.1-1 percent of preservative and the balance of water. In the emamectin benzoate suspending agent, an anion active agent is added, thereby the problems of grinding and livering of the emamectin benzoate are solved. Organic solvent harmful to the human and the environment is not adopted in the invention, thereby reducing pollution of the organic solvent to the environment; besides, the adopted dosage form has lower cost, thereby effectively reducing the solvent cost, the package cost and the transportation expense.

Description

technical field [0001] The invention relates to a emamectin benzoate suspension and a preparation method thereof. Background technique [0002] Emamectin benzoate (abamectin emamectin for short), trade name procloim (banleptm). It is a super efficient green insecticide. Emamectin benzoate is chemically synthesized from abamectin. Abamectin series products are widely used in the fields of medicine, pesticide and veterinary medicine. It is known as another drug revolution after penicillin . Starting from avermectin B1a, the activity of emamectin benzoate synthesized by chemical modification is 10-1000 times higher than that of the parent avermectin, and has ultra-high efficiency, broad spectrum, near non-toxicity, no residue, and no production. The characteristics of drug resistance are considered by the industry to replace other pesticides and become the leading product of pesticides in the 21st century. Emamectin benzoate insecticide has been widely used in the control o...
