Problems solved by technology

However, when preparing suspoemulsions containing low-melting compounds, the use of conventional solvents will lead to unstable phenomena such as crystallization, flocculation, and Ostwald ripening, and the quality of the preparations cannot be guaranteed.
And the use of relatively expensive special solvents such as lactate solvents can solve the problem of the stability of some low-melting compound suspoemulsions, but it will greatly increase the cost of suspoemulsions, seriously restricting the large-scale production of suspoemulsions, and both The component composition cannot combine the functions of sufficient solubility and Oswald ripening inhibitor when some high-cost solvents are selected, so there is an urgent need to break through the bottleneck of low-melting compound formulations that cannot be mass-produced

Abstract

The invention belongs to the technical field of pesticides, and relates to a suspoemulsion pesticide composition (containing a low melting point compound and thiram) and its preparation. The composition contains an active component and a solvent; the active component is compound A and thiram; wherein, compound A is a bactericidal compound with a melting point of less than 90°C; the solvent is at least one aliphatic alcohol or alicyclic compound that dissolves compound A alcohol. The solvent added in the composition of the present invention further develops a broader idea of ​​solvent selection in the suspoemulsion, and breaks through the bottleneck of low-melting compound compound preparations that cannot be produced on a large scale.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a suspoemulsion pesticide composition (containing low melting point compound and thiram) and its preparation. Background technique [0002] Low melting point bactericidal compounds (such as propiconazole, prochloraz, pyridoxazole, chlorpyrifos, trifloxystrobin, imazalil, pyraclostrobin, metalaxyl, metalaxyl, tebufenfen, triflurax There are many challenges in the screening of additives and the production process when preparing preparations. Due to its inherent characteristics of low melting point, the product is prone to crystallization and the suspension rate drops sharply after heat storage. , Poor stability over time and other shortcomings. [0003] Thiram is a dithiocarbamate fungicide and is a protective fungicide. It has a wide bactericidal spectrum and has a good control effect on a variety of crops such as downy mildew, blight, anthracnose, cereal smut, and seedling yel...
