Embodiment 1

[0027] Weigh 5% thiophanate-methyl, 30% pyraclostrobin, 3% propiconazole, 8% sorbitan monostearate (Span 60), phenylethylphenol polyoxyethylene ether (Nongru 602) 4%, fatty alcohol polyoxyethylene ether (Pingping plus O) 5%, organic bentonite 3%, talcum powder 2%, triphenyl phosphite 3%, and methyl oleate make up 100%. The above raw materials are mixed, dispersed at high speed for 20 minutes, and sanded with a sand mill until the particle size is less than 5 microns to obtain 5% thiophanate-methyl·30% pyraclostrobin·3% ​​propiconazole dispersible oil suspending agent.

Embodiment 2

[0029] Weigh 20% thiophanate-methyl, 10% pyraclostrobin, 15% propiconazole, 5% benzyl dimethylphenol polyoxyethylene ether (Nongru 400#), 5% sorbitan monohard Fatty acid ester (Span 80) 8%, castor oil polyoxyethylene ether (EL-40) 5%, polyvinylpyrrolidone 3%, white carbon black 5%, and biodiesel make up 100%. The above raw materials are mixed, dispersed at high speed for 15 minutes, and sanded with a sand mill until the particle size is less than 5 microns to obtain 20% thiophanate-methyl · 10% pyraclostrobin · 15% propiconazole dispersible oil suspending agent.

Embodiment 3

[0031] Weigh 30% thiophanate-methyl, 10% pyraclostrobin, 10% propiconazole, 8% calcium dodecylbenzenesulfonate, 2% sodium lignosulfonate, phenylethylphenol polyoxyethylene Polyoxypropylene ether (Nongru 1601) 5%, white carbon black 3%, attapulgite 2%, corn oil make up 100%. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill until the particle size was less than 5 microns to obtain 30% thiophanate-methyl·10% pyraclostrobin·10% propiconazole dispersible oil suspending agent.

Abstract

The invention discloses a dispersing oil suspending agent containing thiophanate-methyl. The dispersing oil suspending agent comprises the following components in percentage by weight of 3%-60% of thiophanate-methyl, 2%-40% of pyraclostrobin, 3%-50% of propiconazole, 2%-10% of a wetting dispersant, 2%-20% of an emulgator, 1%-10% of a stabilizer, 2%-10% of a potentiating agent, and the balance of solvent. The dispersing oil suspending agent provided by the invention has the advantages that the component is reasonable, the dosage form is environmentally friendly, compared with the single preparation, the preparation has the good sterilizing effect and the prominent synergistic effect, the crop safety is good, and the dispersing oil suspending agent has the excellent control efficiency on sigatoka and macrophoma musae.

Description

technical field [0001] The invention relates to an agricultural fungicide, specifically, the active ingredient is a dispersible oil suspension composed of the first active ingredient thiophanate-methyl, the second active ingredient pyraclostrobin and the third active ingredient propiconazole , belongs to the technical field of pesticides. Background technique [0002] Thiophanate-methyl, also known as thiophanate-methyl, English common name: thiophanate-methyl, chemical name: 1,2-bis-(3-ethoxycarbonyl-α-thioureido)benzene, belongs to benzimidazoles , is a broad-spectrum systemic fungicide, which can prevent and control a variety of crop diseases, and has systemic, preventive and therapeutic effects. It is transformed into carbendazim in plants, which interferes with the formation of the spindle in mitosis of bacteria and affects cell division. It can be used to prevent and control various diseases on cereals, vegetables, fruit trees and other crops. [0003] Pyraclostrobi...
