[0024] Embodiment 1 15% Mesotrione Dispersed Oil Suspension Concentrate

[0025] Mesotrione 15%, fatty alcohol polyoxyethylene ether 4%, polyethylene glycol monooleate 6%, organic bentonite BP183 1.5%, methyl oleate to make up, mix the above components and perform high shear Pre-dispersed, then added to a sand mill, and ground for 3 hours to obtain a sample;

[0026] A stabilizer was added to the sample, and after stirring for 0.5 h, the final formulation was obtained. The amount of stabilizer added is shown in Table 1.

[0027] The contents of the samples before storage and the samples after heat storage were determined by high performance liquid chromatography, and the decomposition rate was calculated. The measurement results are shown in Table 1.

Abstract

The invention belongs to the technical field of pesticides, and in particular relates to a dispersible oil suspension containing mesotrione. The active component of the dispersible oil suspension concentrate contains mesotrione, and a stabilizer is added; wherein, the added amount of the stabilizer accounts for 0.1-5wt% of the dispersible oil suspension concentrate system. The dispersible oil suspension concentrate added with a stabilizer of the present invention can reduce the decomposition of mesotrione in the oil dispersion medium, and can ensure that the relative decomposition rate of mesotrione is below 5% in the thermal storage stability test; Prevent the darkening of the appearance of the preparation, so that the dispersible oil suspension preparation product containing mesotrione maintains the stable state of mesotrione during storage and transportation; the adaptability of the stabilizer involved in the present invention to the original formulation Well, whether it is a single-dose dispersible oil suspension concentrate of mesotrione or a mixed-dose dispersible oil suspension concentrate compounded with other ingredients, the original physical and chemical properties of the preparation have not been affected.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a dispersible oil suspension containing mesotrione. Background technique [0002] Mesotrione, also known as "Mesotrione", is a pre-emergence and post-emergence broad-spectrum selective herbicide capable of inhibiting hydroxyphenylpyruvate dioxygenase (HPPD), which can effectively control the main broad-spectrum Leaf grass and some grass weeds. Mesotrione is easy to conduct in plant xylem and phloem, and has contact killing effect and specific effect. [0003] The development of dispersible oil suspension concentrates began in the late 1970s and gradually developed in the 1980s. Since the application effects of water-based and granulated products, especially the drug efficacy, are still far behind those of emulsifiable concentrate preparations in many cases, dispersible oil suspension concentrates are an ideal choice in some cases. [0004] Mesotrione is prepared...
