Problems solved by technology

[0003] Traditional prochloraz has three dosage forms: microemulsion, water emulsion, and emulsifiable concentrate. These three dosage forms are insufficient in terms of quick-acting, long-lasting, and environmental protection. They all have the problem of poor drug efficacy and require a larger dose. Only prochloraz can achieve the purpose of killing insects
Especially for the prochloraz product of the emulsifiable concentrate type, the solvents used are mainly aromatic hydrocarbons such as toluene and xylene. These substances are not easy to degrade, that is, they pollute the environment and waste a large amount of petroleum resources, which do not meet the requirements of sustainable agricultural development and trend

Embodiment 1

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

[0016] Liquid prochloraz 20%, emulsifier FS-7PG (nonionic and anionic mixed surfactant, produced by Takemoto Oil) 8%, water-soluble polymer polyvinyl alcohol (PVA) 8%, and the rest is supplemented by carrier sodium benzoate. First mix prochloraz and emulsifier evenly, then the mixed prochloraz is added to 10% polyvinyl alcohol (PVA) aqueous solution (PVA and water are made into an aqueous solution at a ratio of 1:10), and mixed evenly to obtain a viscous Emulsion, then adding the carrier sodium benzoate to the viscous emulsion to obtain a pre-granulation mixture, finally granulation and drying.

Embodiment 2

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

[0018] Liquid prochloraz 30%, emulsifier SB-75 (non-ionic and anionic mixed surfactant, produced by Takemoto Oil) 10%, water-soluble polymer carboxymethyl starch sodium (CMS) 10%, the rest is carrier Yuanming Powder make up. First mix prochloraz and emulsifier evenly, then the mixed prochloraz is added to 8% carboxymethyl starch sodium (CMS) aqueous solution (CMS and water are made into aqueous solution at 1:8), and mixed evenly to obtain viscous Thick emulsion, and then adding the carrier sodium bicarbonate to the viscous emulsion to obtain a pre-granulated mixture, finally granulated and dried.

Embodiment 3

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

[0020] Liquid prochloraz 40%, emulsifier FS-7PG (nonionic and anionic mixed surfactant, produced by Takemoto Oil) 12%, water-soluble polymer sodium carboxymethylcellulose (CMC) 12%, the balance is carrier sulfuric acid Ammonium supplementation. First mix prochloraz and emulsifier evenly, then the mixed prochloraz is added to 12% carboxymethylcellulose sodium (CMC) aqueous solution (CMC and water are made into an aqueous solution at 1:12), and mixed 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 prochloraz emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The prochloraz emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of prochloraz, 8%-12% of emulsifying agent, 8%-12% of water-soluble polymer, and the balance of carriers. The preparation method comprises the following steps: mixing liquid prochloraz and the emulsifying agent uniformly firstly; adding prochloraz 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 maintain a long-term superiority effect, and achieve good effect at low concentration.

Description

technical field [0001] The invention relates to a pesticide fungicide, in particular to a prochloraz fungicide and a preparation method of the prochloraz fungicide. Background technique [0002] Prochloraz is a high-efficiency, broad-spectrum, low-toxic fungicide, which has multiple functions such as systemic conduction, prevention, protection and treatment, and works by inhibiting the biosynthesis of sterols. The diseases caused by Ascomycetes and Deuteromycetes have obvious control effects, and can also be mixed with most fungicides, insecticides, and herbicides, all of which have good control effects. It can treat and eradicate many diseases on field crops, fruits and vegetables, turf and ornamental plants. [0003] Traditional prochloraz has three dosage forms: microemulsion, water-emulsion, and emulsifiable concentrate. These three dosage forms are not enough in terms of quick-acting, long-lasting, and environmental protection. They all have the problem of poor drug ef...
