Embodiment 1

[0021] Example 1: 10% pymetrozine water dispersible granules

[0022] Each component is (weight):

[0023] Pymetrozine 10 parts

[0024] 25 parts of polycarboxylate

[0025] Sodium Carboxymethyl Starch 12 parts

[0026] Sodium p-methoxy fatty acid amide benzene sulfonate 12 parts

[0027] Sodium carboxymethyl cellulose 10 parts

[0028] 31 parts of anhydrous sodium sulfate

[0029] Pymetrozine and other additives except the binder are crushed and mixed in a gravity-free mixer according to the formula ratio for 20 minutes, and then the mixture is put into a double screw mixer (Ⅰ), and the mixture is crushed by airflow while mixing It is crushed to a particle size of more than 1000 meshes, collected by a cyclone separator and a bag filter, and finally mixed with a double screw mixer (II) to obtain a uniform powder. Then accurately weigh a quantitative amount of powder in a boiling granulator, spray the binder according to the formula, and dry to obtain a granular water-dispersible granule ...

Abstract

The invention discloses a pymetrozine water dispersing granule and a preparation method thereof. The pymetrozine water dispersing granule comprises the following components in percentage by weight: 5%-80% of pymetrozine, 2%-25% of dispersing agents, 2%-20% of disintegrating agents, 1%-15% of wetting agents, 0.1%-10% of cementing agents, and the balance of fillers complemented to 100%. The invention has stable physical and chemical property and difficult decomposition and degeneration, needs no organic solvent, has no dust entrainment, can not burn and explode, saves the petroleum resources, reduces the environmental pollution, is safe for operators and environments in the production and usage process, can be processed into a high-content preparation as required and saves the packing, storage and transportation cost.

Description

Technical field [0001] The invention belongs to the field of pesticide formulations, and specifically relates to a pymetrozine water dispersible granule and a preparation method. Background technique [0002] Pymetrozine is a pyridine or triazinone insecticide. It is a brand-new non-biocidal insecticide. It was first developed by Ciba-Geigy of Switzerland in 1988. This product is a piercing and sucking mouthpart for various crops. Pests show excellent control effects. Research using electro-penetration graph (EPG) technology shows that whether it is drip, feeding or injection test, as long as the aphids or planthoppers come into contact with pymetrozine, the needle blocking effect will occur almost immediately, and the feeding will be stopped immediately, and finally starvation Fatal, and the process is irreversible. Therefore, pymetrozine has an excellent function of blocking insect transmission. Although the mechanism of stylus obstruction caused by pymetrozine is still uncl...
