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 suspending agent containing chlorantraniliprole and lambda-cyhalothrin. The suspending agent is mainly applied to control of insect pests on crops. The lambda-cyhalothrin is low in melting point, so that dosage form of the lambda-cyhalothrin at present is mainly emulsified after being dissolved, and is mainly missible oil, a microemulsion and an emulsion in water, but the three dosage forms contain benzene organic solvents, and are not environmental dosage forms in true sense. By adopting the suspending agent, the complex suspending agent of the chlorantraniliprole and the lambda-cyhalothrin is introduced, does not contain an organic solvent, does not contain carcinogenic, teratogenic or mutagenic agents, and is the environmental dosage form in true sense. The composition comprises the main effective components of 1-20% of chlorantraniliprole, 1-10% of lambda-cyhalothrin, 3-6% of dispersing agent, 1-2% of wetting agent, 1-2% of stabilizer, 0.1-0.2% of defoamer, 0.2-5% of suspending agent, 3-5% of antifreezing agent and the balance of water. The insecticidal compound suspending agent belongs to an environment-friendly pesticide, is free of three wastes in production, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of pesticide formulations, in particular to a chlorantraniliprole-effective-cyhalothrin suspension 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 othe...
