Problems solved by technology

[0003] At present, diazinon has three dosage forms: microemulsion, water emulsion and emulsifiable concentrate, but these three dosage forms are not enough in quick effect, long-lasting effect and environmental protection. Diazinon can achieve the purpose of killing insects
Moreover, the solvents used in emulsifiable concentrate (EC) are mainly aromatic hydrocarbons such as toluene and xylene, which pollute the environment and waste a lot of petroleum resources, which do not meet the requirements and trends of sustainable agricultural development

Embodiment 1

[0015] Example 1: 20% diazinon emulsifiable granules.

[0016] Liquid diazinon 20%, emulsifier YUS-FS1 (non-ionic phosphate, produced by Takemoto Oil) 5%, water-soluble polymer polyvinyl alcohol (PVA) 8%, and the balance is supplemented by carrier ammonium bicarbonate. First, mix diazinon and emulsifier evenly, then add the mixed diazinon into 10% polyvinyl alcohol (PVA) aqueous solution (PVA and water are made into an aqueous solution at a ratio of 1:10), mix evenly to obtain a viscous Emulsion, and the carrier ammonium bicarbonate is added to the viscous emulsion to obtain a pre-granulation mixture, which is finally granulated and dried.

Embodiment 2

[0017] Example 2: 30% diazinon emulsifiable granules.

[0018] Liquid diazinon 30%, emulsifier YUS-SB75 (nonionic and anionic mixed surfactant, produced by Takemoto Oil) 8%, water-soluble polymer carboxymethyl starch sodium (CMS) 10%, the balance is carrier sodium benzoate make up. First, mix diazinon and emulsifier evenly, then add the mixed diazinon into 8% carboxymethyl starch sodium (CMS) aqueous solution (CMS and water are made into an aqueous solution at a ratio of 1:8), mix evenly to obtain a viscous Thick emulsion, then adding the carrier sodium benzoate to the viscous emulsion to obtain a pre-granulated mixture, finally granulated and dried.

Embodiment 3

[0019] Example 3: 40% diazinon emulsifiable granules.

[0020] Liquid diazinon 40%, emulsifier YUS-CH7000 (nonionic and anionic mixed surfactant, produced by Takemoto Oil) 9%, water-soluble polymer sodium carboxymethylcellulose (CMC) 12%, the balance is carrier sulfuric acid Ammonium supplementation. First mix diazinon and emulsifier evenly, then the mixed diazinon is added to 12% carboxymethylcellulose sodium (CMC) aqueous solution (CMC and water are made into an aqueous solution at 1:12), and mix evenly to obtain A viscous emulsion, and the carrier ammonium sulfate is added to the viscous emulsion to obtain a pre-granulated mixture, which is finally granulated and dried.

Abstract

The invention relates to diazinon emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The diazinon emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of diazinon, 5%-10% of emulsifying agent, 8%-12% of water-soluble polymer, and the balance of carriers. The preparation method comprises the following steps: mixing liquid diazinon and the emulsifying agent uniformly firstly; adding diazinon after mixing into a water solution of the water soluble polymer, and mixing uniformly, thus viscous emulsion is obtained; then adding the carriers into the viscous emulsion, thus a pre-granulating mixture is obtained; and finally granulating and drying. The granules provided by the invention are emulsifiable granules without adding an organic solvent, can be completely emulsified by adding water in use, can achieve good effect at low concentration, have quick acting and duration, and can maintain a long-term superior effect; and bactericidal effect is superior to other dosage forms with the same active ingredients.

Description

technical field [0001] The invention relates to a pesticide insecticide, in particular to a diazinon-emulsifiable granule and a preparation method of the diazinon-emulsifiable granule. Background technique [0002] Diazinon is a broad-spectrum, high-efficiency, and low-toxic organophosphorus pesticide (insecticide and acaricide), which has contact killing, stomach poisoning, fumigation, and certain systemic effects. Its mechanism of action is to inhibit acetylcholinesterase. , Homoptera and other pests have good control effects, and can also be used for seed dressing to control underground pests. It is suitable for the control of crop pests and mites in tea, fruit, cotton, rice, wheat, vegetables, flowers and other crops. [0003] At present, diazinon has three dosage forms: microemulsion, water emulsion and emulsifiable concentrate, but these three dosage forms are not enough in quick effect, long-lasting effect and environmental protection. Diazinon can achieve the purpos...
