Problems solved by technology

[0012] Seed treatment agents containing a single active component are frequently used, the actual effect is poor, and the scope of action is narrow, and the purpose of simultaneously eliminating pests and pathogens cannot be achieved
Although prothioconazole, abamectin, emamectin benzoate, and chlorpyrifos are highly effective as fungicides and insecticides, their single-dose use for a long time will easily cause diseases and pests to develop drug resistance, resulting in increased dosage, The problem of reduced prevention effect and shortened duration is not conducive to the sustainable development of the environment

Embodiment 1

[0096] Embodiment 1: 32% prothioconazole, abamectin, chlorpyrifos seed treatment suspension agent (1:1:30)

[0097] Components: prothioconazole 1.0%, abamectin 1.0%, chlorpyrifos 30.0%, styrene maleic anhydride copolymer sodium salt 4.0%, polyoxyethylene polyoxypropylene ether block copolymer 2.0%, polyethylene Pyrrolidone 0.5%, ethylene glycol 5%, xanthan gum 0.15%, silicone antifoaming agent 0.1%, rose essence 0.2%, cassone 0.5%, water to make up to 100%.

[0098] Preparation method: Mix the components, mix them evenly through high-speed shearing, and then sand them through a sand mill for 2-3 hours to make the average particle size reach 1-5 microns, and then 32% prothioconazole can be prepared. Vermectin. Chlorpyrifos Seed Treatment Suspension.

Embodiment 2

[0105] Embodiment 2: 42% prothioconazole, abamectin, chlorpyrifos seed dry powder (1:10:10)

[0106] Ingredients: Prothioconazole 2.0%, Abamectin 20.0%, Chlorpyrifos 20.0%, Sodium Lignin Sulfonate 4.0%, Hydroxyethyl Cellulose 0.5%, Silica 15.0%, Rhododendron 0.3%, Talc Top up to 100%.

[0107] Preparation method: the components are mixed evenly, firstly subjected to mechanical pulverization, and then through jet pulverization, and then mixed evenly to obtain 42% prothioconazole, avermectin and chlorpyrifos seed treatment dry powder.

Embodiment 3

[0111] Example 3: 32% prothioconazole, abamectin, chlorpyrifos seed treatment microcapsule suspension (1:30:1)

[0112] Components: Prothioconazole 1.0%, Abamectin 30.0%, Chlorpyrifos 1.0%, Dimethylolurea 3.0%, Gum Arabic 0.5%, Styrene maleic anhydride copolymer sodium salt 2.0%, Citric acid 1.0% , Sodium Lignin Sulfonate 2.0%, Alkyl Phenol Polyoxyethylene Ether Phosphate 3.0%, Ethylene Glycol 3.0%, Xanthan Gum 0.15%, Silicone Defoamer 0.1%, Cassone 0.5%, Rhododendron 0.2% , topped up to 100%.

[0113] Preparation method: prothioconazole, abamectin and chlorpyrifos are wet-pulverized to prepare a suspension, dimethylol urea and gum arabic are added, and a polyurea reaction is induced under acidic conditions to form a coating on the active ingredients , and finally adding ethylene glycol, xanthan gum and other structural regulators to obtain 32% prothioconazole. abamectin. chlorpyrifos seed treatment microcapsule suspension.

Abstract

The invention discloses a seed treating agent composition and applications thereof, and relates to the technical field of pesticide compounding. The composition comprises an effective component A, aneffective component B and an effective component C, wherein the effective component A is prothioconazole, the effective component B is avermectin or derivatives thereof, and the effective component Cis chlorpyrifos. The weight ratio of the effective component A, the effective component B and the effective component C is 1-30:1-30:1-30. Seed treating agents can take effects from different target points, can kill pests and achieve sterilization, and provides comprehensive protection for seeds. The composition is good in environment compatibility, low in toxicity, and safe to human, livestock, natural enemies, and the like, and is a wide-spectrum and efficient seed treating agent composition. The composition has high synergistic effects, reduces the application cost, and has control effectsobviously superior to control effects when a single agent is used. The composition has obvious popularization value.

Description

technical field [0001] The present invention relates to a seed treatment composition and application thereof, in particular to a seed treatment composition containing prothioconazole, abamectin or derivatives thereof and chlorpyrifos as active ingredients and application thereof, belonging to the compound pesticide compound with the technical field. Background technique [0002] Seed treatment agent is a kind of pesticide used for the surface treatment of seeds. The active ingredients are mainly insecticides or fungicides. Compared with conventionally used stem and leaf treatment pesticides, seed treatments have obvious advantages in reducing the amount and frequency of pesticide application, reducing environmental pollution, reducing field operation procedures, saving labor, saving costs, and increasing efficiency. [0003] The seed treatment technology that my country has vigorously advocated and promoted in recent years is mainly to compound pesticides, fungicides, compo...
