Problems solved by technology

[0003] At present, the conventional dosage forms of chlorpyrifos are microemulsion, water emulsion, and emulsifiable concentrate. The dose of chlorpyrifos can achieve the purpose of killing insects
Moreover, the solvents used in EC formulations 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% chlorpyrifos emulsifiable granules.

[0016] Liquid chlorpyrifos 20%, emulsifier FS-7PG (nonionic and anionic mixed surfactant, produced by Takemoto Oil) 5%, water-soluble polymer polyvinyl alcohol (PVA) 8%, and the rest is supplemented by carrier sodium benzoate. First mix chlorpyrifos and emulsifier evenly, then add the mixed chlorpyrifos 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, The carrier sodium benzoate is then added to the viscous emulsion to obtain a pre-granulated mixture, which is finally granulated and dried.

Embodiment 2

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

[0018] Liquid chlorpyrifos 30%, emulsifier SB-75 (non-ionic and anionic mixed surfactant, produced by Takemoto Oil) 8%, water-soluble polymer carboxymethyl starch sodium (CMS) 10%, the rest is supplemented by carrier sodium sulfate . First mix chlorpyrifos and emulsifier evenly, then the mixed chlorpyrifos is added to an aqueous solution of 8% sodium carboxymethyl starch (CMS) (CMS and water are made into an aqueous solution at a ratio of 1:8), and mixed evenly to obtain a viscous emulsion. Then add the carrier sodium sulfate into the viscous emulsion to obtain a pre-granulated mixture, which is finally granulated and dried.

Embodiment 3

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

[0020] Liquid toxin 40%, emulsifier FS-7PG (non-ionic and anionic mixed surfactant, produced by Takemoto Oil) 8%, water-soluble polymer sodium carboxymethylcellulose (CMC) 10%, the balance is carrier sulfuric acid Ammonium supplementation. First mix chlorpyrifos and emulsifier evenly, then add the mixed chlorpyrifos into 12% sodium carboxymethylcellulose (CMC) aqueous solution (CMC and water are made into an aqueous solution at 1:12), mix well to obtain a viscous emulsion , and then 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 chlopyrifos emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The chlopyrifos emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of chlopyrifos, 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 chlopyrifos and the emulsifying agent uniformly firstly; adding chlopyrifos 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 have quick acting and duration, can be completely emulsified by adding water in use, and can achieve good effect at low concentration; and bactericidal effect is superior to other dosage forms with the same active ingredients.

Description

Technical field [0001] The present invention involves a pesticide pesticide, which specifically involves a preparation method for a poisonous cricket can be emulsified and poisonous crickets can be emulsified. Background technique [0002] Poisonous death is a pesticide pesticide with a wide range of insecticidal spectrum. It has the effect of gastric poisoning, touching, and fumigation. It is a acetylcholine inhibitor. It is easy to combine the organic matter in the soil.The safety of consumers has better preventive effect on rice, wheat, cotton, fruit, vegetables, vegetables, and tea trees. [0003] At present, the routine use dosage forms of poisonous death are three types of dosage, water emulsion, and emulsion oil.Dose poisonous crickets can achieve insecticidal purposes.And the solvents used in the dosage of milk (EC) are mainly aromatics such as toluene and dystershopine. They also waste a large amount of oil resources and do not meet the requirements and trends of sustain...
