Embodiment 1

[0020] Embodiment 1: 10% acetamiprid water-dispersible granules

[0021] Each component is (weight):

[0022] Acetamiprid 10 parts

[0023] Sodium methylene bis-naphthalene sulfonate 25 parts

[0024] Sodium carboxymethyl starch 12 parts

[0025] Sodium p-methoxy fatty amidobenzene sulfonate 12 parts

[0026] Sodium carboxymethyl cellulose 10 parts

[0027] Anhydrous sodium sulfate 31 parts

[0028] After pulverizing acetamiprid and other additives except for the binder, pre-mix in a gravity-free mixer for 20 minutes according to the formula ratio, then put the mixture into a double-screw mixer (I), and pulverize it by airflow while mixing. Machine pulverization to reach a particle size of more than 1000 mesh, collected by a cyclone separator and a bag filter, and finally mixed again in a double-screw mixer (II) to obtain a uniform powder. Then accurately weigh the quantitative powder into the fluidized granulator, spray into the binder according to the formula, dry to o...

Abstract

The invention discloses an acetamiprid water dispersible granule, which comprises the compositions by weight portion of: 5 to 80 percent of acetamiprid, 2 to 25 percent of dispersant, 2 to 20 percent of disintegrant, 1 to 15 percent of wetting agent, 0.1 to 10 percent of binder and others filler which is added for up to 100 percent. The acetamiprid water dispersible granule of the invention has the advantages of stable physical and chemical properties, not easy to be decomposed and degenerated. The acetamiprid water dispersible granule is not require to use organic solvents, and has no floating powder, no inflaming and exploding possibility, thus saving petroleum resources and reducing environmental pollution, being safe to operators and environment in producing and using; the preparation with high content can be processed according to the needs, and also has the advantages of saving cost of packaging, storing and transporting.

Description

technical field [0001] The invention belongs to the field of pesticide formulations, and in particular relates to acetamiprid water-dispersible granules and a preparation method. Background technique [0002] Acetamiprid is a neonicotinoid biomimetic insecticide. The combination of the insecticide with the acetylcholine receptor in the insect body makes the insect extremely excited, and the whole body convulses, paralyzes and dies. Only 0.5 grams of active ingredients are used per mu. It can control the harm of field pests. It is one of the pesticides with the lowest dosage at present, and it is moderately toxic. The insecticide is also effective against pests resistant to pyrethroids, organophosphates, and carbamates. It is suitable for controlling various pests of cotton, rice, fruit trees, vegetables, dry food crops, tea trees, tobacco and other crops, especially for Lepidoptera pests, Homoptera pests, Coleoptera pests, and Thrips pests. At present, the commonly used do...
