Analysis of application scenarios: The diversified role of N-formylmorpholine aromatic solvents in pesticide preparations
In the field of pesticide preparations, N-formylmorpholine aromatic solvents (NFM aromatic solvents) show diverse application scenarios due to their unique performance and versatility. Whether used to formulate specific types of pesticide formulations or to solve certain specific problems, NFM aromatic solvents play a crucial role.
Formulate oil suspension agent (OD)
Oil Dispersion (OD) is a new form of pesticide preparation, which has attracted widespread attention due to its efficient and environmentally friendly characteristics. NFM aromatic solvents mainly act as solvents and co-dispersants in such formulations. By dissolving the active ingredient in NFM aromatic solvent and mixing it with water, a stable water-in-oil or oil-in-water system can be formed. This system not only improves the dispersion uniformity of the active ingredients, but also significantly enhances the stability of the preparation and extends the shelf life of the product.
For example, when formulating an oil suspension agent containing cypermethrin, the NFM aromatic solvent is able to completely dissolve cypermethrin and act in concert with the emulsifier to form stable suspended particles with a particle size less than 1 μm. These tiny particles are more likely to adhere to the plant surface during spraying, thereby improving the efficacy of the medicine.
Preparation of emulsion oil (EC)
Emulsifiable Concentrate (EC) is another common form of pesticide preparation. The main function of NFM aromatic solvents here is to dissolve the active ingredients and form a uniform oil phase. When the emulsion preparation is diluted, the NFM aromatic solvent can be quickly emulsified with the aqueous phase.A stable emulsion is formed to ensure that the active ingredients are evenly distributed throughout the solution.
Take imidacloprid emulsion as an example, NFM aromatic solvent can not only completely dissolve imidacloprid, but also form emulsion particles with particle size less than 2μm during the dilution process. This particle size not only ensures the stability of the medicine liquid, but also improves the coverage area and penetration capacity during the spraying process.
Solve special problems
In addition to conventional formulation forms, NFM aromatic solvents can also be used to solve some special agricultural problems. For example, when controlling resistant pests, a compound pesticide preparation is required. NFM aromatic solvents can effectively dissolve a variety of active ingredients to form compound preparations, enhancing drug efficacy while reducing the risk of resistance.
In addition, when pesticides are used in cold areas, low temperatures may cause the formulation to freeze or delaminate. Due to its low freezing point and good low temperature stability, NFM aromatic solvents can effectively avoid these problems and ensure the normal use of the preparation under various climatic conditions.
| Preparation type | Main Function | Sample Application |
|---|---|---|
| Oil Suspension Agent (OD) | Improving dispersion and stability | Cyclothrin Oil Suspension Agent |
| Embroidery (EC) | Form a stable emulsion | Iimacloprid Emulsion |
| Compound formulation | Enhance the efficacy of the drug and reduce the risk of resistance | Multiple pesticide compound preparations |
| Clow-temperature preparations | Provides low temperature stability | Special preparations for cold areas |
From the above analysis, it can be seen that the application of N-formylmorpholine aromatic solvents in pesticide preparations is not limited to a single function, but their use can be flexibly adjusted according to different needs. This flexibility and versatility make it an indispensable and important tool in modern agriculture.
