Problems solved by technology

Excessive release of calcium ions in the intracellular calcium pool leads to paralysis and death of insects. It has high activity against larvae of lepidopteran pests, wide insecticidal spectrum and good persistence. According to the current test results, the activity against target pests is higher than other products. 10-100 times higher. And it can cause disorder in the mating process of some Lepidoptera insects. Studies have shown that it can reduce the egg-laying rate of a variety of Noctuidae pests

Abstract

The invention discloses a chlorantraniliprole-emamectin benzoate suspending agent and a preparation method thereof. The chlorantraniliprole-emamectin benzoate suspending agent is mainly used for preventing and treating insect pests on crops. The effective components of the composition comprise 1-20% of chlorantraniliprole, 1-10% of emamectin benzoate, 3-6% of a dispersant, 0.5-3% of a lubricant, 0.1-1% of a stabilizer, 0.05-0.2% of a defoamer, 0.2-5% of a suspending agent, 3-5% of an antifreezing agent and the balance of water. The insecticidal compound suspending agent is a green and environment-friendly pesticide which is free from three wastes in production and convenient to use.

Description

technical field [0001] The invention relates to the technical field of pesticide formulations, in particular to a suspension of chlorantraniliprole and emamectin benzoate and a preparation method thereof. Background technique [0002] The trade name of chlorantraniliprole is Kangkuan, and its chemical name is: 3-bromo-N-[4-chloro-2-methyl-6-[(methylcarbamoyl)benzene]-1-(3-chloropyridine- 2-yl)-1-hydrogen-pyridine-5-carboxamide, its structural formula is as follows: [0003] [0004] The appearance of pure chlorantraniliprole technical product is white crystal, specific gravity (requirement for liquid) 1.507g / mL, melting point 208-210°C, decomposition temperature 330°C, vapor pressure (20~25°C) 6.3×10 12 Pa, solubility (20~25, mg / L): water 1.023, acetone 3.446, methanol 1.714, acetonitrile 0.711, ethyl acetate 1.144. Chlorantraniliprole is an o-formamidobenzamide insecticide. Because the chemical structure of chlorantraniliprole has a new insecticidal principle that no ...
