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 an effervescent granule containing chlorantraniliprole and emamectin benzoate. The effervescent granule is mainly applied to control of insect pests on crops. The composition comprises the effective components of 1-20% of chlorantraniliprole, 1-20% of emamectin benzoate, 2-10% of dispersing agent, 1-5% of wetting agent and 1-5% of stabilizer, and also comprises 0.5-20% of disintegrating agent, 5-20% of acid source, 5-20% of carbon dioxide gas source, 0.01-2% of binder and the balance of inert filler. The invention simultaneously discloses a preparation method of the effervescent granule. The method comprises the following steps: firstly, crushing raw materials into particles with the particle size of less than 10 microns by a jet mill, and mixing by a mixer; and simultaneously adding binder slurry, evenly mixing, and then drying and screening to prepare the effervescent granule by an effervescent pelletizer. The effervescent granule is free of pollution on environment, fast to disintegrate, accurate to meter and convenient to use. The insecticidal compound effervescent granule belongs to an environment-friendly pesticide, and is free of three wastes in production and convenient to use.

Description

technical field [0001] The invention relates to the technical field of pesticide dosage forms, in particular to a chlorantraniliprole-amamectin emamectin effervescent granule 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...
