Abstract

The invention discloses a pymetrozine suspension seed coating agent and a preparation method of the pymetrozine suspension seed coating agent. The suspension seed coating agent comprises the following components by weight: 5-60 parts of pymetrozine, 3-30 parts of dispersing agent, 0.1-10 parts of stabilizing agent, 0.1-10 parts of film forming agent, 0.1-10 parts of antifoaming agent, 1-10 parts of anti-freezing agent, 0.1-10 parts of penetrating agent, 0.2-10 parts of preservative, and 0.5-10 parts of colouring agent, adding water to complement the number of the materials to be 100 parts. The pymetrozine suspension seed coating agent has the advantages of low toxicity, good pesticide effects, long duration, high safety and convenience in use, can reduce the environment pollution, improve the pesticide utilization rate, and reduce the usage amount of the pesticides.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a pymetrozine suspension seed coating agent and a preparation method thereof. Background technique [0002] Pymetrozine, the structural formula is as follows, chemical name: (E)-4,5-2 hydrogen-6-methyl-4-(3-pyridylmethylamine)-1,2,4-triazine- 3(2H)-one. [0003] Pymetrozine is a high-efficiency and low-toxic insecticide. It is safe for the environment, humans, livestock, natural enemies of pests and other beneficial organisms. It is not easy to produce resistance to pest control. It is an environmentally friendly insecticide. Powder, suspending agent, but there is no suspension seed coating agent specially used for seed dressing. The chemical structural formula of pymetrozine is as follows: [0004] Contents of the invention [0005] The purpose of the present invention is to uniformly disperse pymetrozine in deionized water as solid particles with small particle dia...
