Problems solved by technology

[0007] At present, 5% uniconazole wettable powder is the most widely used in the market. Its product has a large particle size and poor adhesion. During use, there are problems such as polluting the environment and damaging the health of operators.
200510090044.9 discloses the microemulsion formula that mepiperium and uniconazole are mixed as active ingredients, but so far, the single-component microemulsion with uniconazole as active ingredients has not been reported

Embodiment 1

[0025] A kind of uniconazole microemulsion is made up of following components by mass percentage:

[0026]

[0027] Mix the above components thoroughly in proportion, slowly add water under stirring, heat and stir at 40°C for 30 minutes, the system changes from W / O type to O / W type, and cool at room temperature to obtain the product.

Embodiment 2

[0029] A kind of uniconazole microemulsion is made up of following components by mass percentage:

[0030]

[0031] Mix the above components thoroughly in proportion, slowly add water under stirring, heat and stir at 40°C for 30 minutes, the system changes from W / O type to O / W type, and cool at room temperature to obtain the product.

Embodiment 3

[0033] Dilute the uniconazole microemulsion provided by the invention to a concentration of 0.25mg / L, 0.5mg / L, 1.0mg / L, 2.0mg / L, and act on wheat seedlings.

[0034] 1. Effect on germination potential and germination rate of wheat

[0035] Germination potential and germination rate are indicators for detecting the germination quality of seeds. Cultivated in a dark box at 25°C, when the concentration was 1.0mg / L microemulsion soaked seeds, the germination potential increased by 5.82% compared with the wettable powder contrast, and decreased by 14.29% compared with the clear water contrast; High, at 86.65%. The research results showed that wheat seeds germinated neatly under the soaking of uniconazole microemulsion. See Table 1 and Table 2 for specific experimental data.

Abstract

The invention discloses a uniconazole microemulsion, a preparation method and an application. The microemulsion components include uniconazole, a solvent, a surfactant, a cosurfactant, an antifreezing agent and water. The uniconazole microemulsion provided by the invention is nano-scale, has obvious dwarfing effect of seedling soaking, good stability, small and uniform particle size, high drug efficacy, high transmission efficiency and permeability, and is helpful for plant absorption , better play the efficacy.

Description

technical field [0001] The invention relates to a plant growth regulator and its preparation method and application, in particular to a nano-level uniconazole microemulsion, its preparation method and application. Background technique [0002] Uniconazole chemical name: (E)-(RS)-1-p-chlorophenyl-2-(1,2,4-triazol-1-yl)-4,4-dimethyl-1-pentene -3-ol. [0003] Structural formula: [0004] [0005] Uniconazole is a triazole plant growth regulator. From the perspective of physiology and molecular level, it mainly regulates plant growth by inhibiting the synthesis of gibberellin and affecting the activity of indole acetic acid oxidase. Its biological effects include dwarfing plants, lodging resistance, anti-virus, bactericidal and so on. It has a strong growth inhibitory effect on herbaceous or woody monocotyledonous or dicotyledonous plants. The method of application can be root application, spray application and seed bud dipping. [0006] Pesticide microemulsion is an envi...
