Description

Technical Field

[0001] This invention relates to the field of pesticide manufacturing technology, and in particular to a non-selective herbicide composition aqueous solution and its preparation method. Background Technology

[0002] The use of herbicides not only ensures high and stable agricultural yields, improves labor productivity and working conditions, but also promotes innovation in cultivation techniques. However, herbicide technology is facing multiple challenges and opportunities, such as increasingly serious resistance problems, the gradual decline in the effectiveness of traditional herbicides, and increasingly stringent requirements for environmental protection and food safety. On the one hand, this prompts researchers to continuously explore new mechanisms of action and active compounds; on the other hand, it also accelerates the development of safer and more environmentally friendly herbicide formulations.

[0003] Glyphosate is a non-selective, residue-free, non-selective herbicide that is highly effective against perennial rooted weeds. It is widely used in rubber, mulberry, tea, orchards, and sugarcane fields. Its CAS number is 1071-83-6. Glyphosate primarily inhibits enolpyruvylshikimate phosphate synthase in plants, thereby inhibiting the conversion of shikimate to phenylalanine, tyrosine, and tryptophan, interfering with protein synthesis and leading to plant death.

[0004] Existing glyphosate aqueous formulation synergists suffer from problems such as insignificant synergistic effects, high toxicity, environmental unfriendliness, easy stratification at low temperatures, and the formation of flocculent insoluble substances. Therefore, developing safer and more environmentally friendly herbicide formulations is of great significance. This invention improves the stability of the formulation system by optimizing the formulation and adding adjuvants, which can significantly enhance the herbicidal activity and provide a new solution for agricultural production.

[0103] Example 1: Determination of key performance indicators:

[0104] The performance indicators of the aqueous solution prepared in this application were determined using conventional testing methods in the art.

[0105] 1) Thermal storage stability: The test was conducted according to method 2.1 in GB / T 19136-2003.

[0106] 2) Low temperature stability: determined according to method 2.1 in GB / T 19137-2003.

[0107] 3) Freezing stability: Stored at -18℃ for 14 days;

[0108] 4) Persistent foaming property: Tested according to GB / T 28137-2011.

[0109] 5) Determination of wettability and permeability: Comply with the relevant provisions of HG / T 2575-94.

[0110] It is made of 21-count 3-ply and 21-count 4-ply fine cotton canvas, in a circular shape with a diameter of 35mm.

[0111] Measurement Procedure: After the foam in the test sample diluent has completely disappeared, place the canvas sheet on the copper wire frame and carefully lower it horizontally onto the surface of the diluent. Immediately start the stopwatch and record the time (s) until the canvas disc begins to settle. Prepare 200ml of each test sample solution (100x dilution) using distilled water (or tap water) and place them in a 250ml beaker. Record the time from placement to the start of settling. When the sample diluent penetrates into the fibers of the canvas disc and its specific gravity is greater than that of the sample diluent, the canvas disc begins to settle. Record the time (s) from placement to the start of settling. A short complete wetting time and a short settling time indicate that the addition of a penetrant in the formulation effectively reduces surface tension and that the penetrant has strong wetting and penetrating properties.

[0112] 6) Measurement of surface tension:

[0113] Prepare a 100-fold dilution of each test sample using distilled water (or tap water), with 200 ml of each solution placed in a 250 ml beaker. Measure the surface tension of the test samples using the platinum plate method at 20°C.

[0114] The test results and the measurement results of relevant performance indicators are shown in the table below:

[0115] Table 1. Results of stability tests

[0116]

[0117] Table 2 Performance Index Measurement Results

[0118]

[0119]

[0120] As can be seen from Table 2, the aqueous solution containing glyphosate of the present invention has good wetting and penetration properties, low surface tension, low foaming, and all other indicators are qualified.

[0121] Example 2: Hydrophilic / Hydrophilic leaf surface retention test:

[0122] Experimental method: The prepared sample was diluted with deionized water to 0.1% (w / w), and then transferred to a beaker by ultrasonic vibration; then...

[0123] Experimental targets: morning glory and foxtail grass;

[0124] Collect fresh morning glory or foxtail grass leaves, prepare regular leaves using a hole punch, and measure the leaf area S (cm²). 2 Immerse the leaves in the solution for 15 seconds, remove them vertically and suspend them for 30 seconds until no more droplets drip down. Weigh the leaves, M1. Finally, calculate the masses M0 and M1 of the leaves before and after treatment. l Take multiple measurements and average the results.

[0125] Formula for calculating retention: Rm = (M l -M0) / S

[0126] Results: Table 3 shows that the adsorption and adhesion of the samples (Preparation Example 1, Preparation Example 2, Preparation Example 3, Preparation Example 4, and Preparation Example 5) on the leaf surface per unit leaf area were enhanced.

[0127] Table 3. Test of water retention on hydrophilic and hydrophobic leaves.

[0128]

[0129] Example 3: Compatibility test with pre-emergent herbicides

[0130] Pre-emergent herbicides primarily act on the soil to prevent weed seed germination, while glyphosate is a systemic herbicide that effectively kills existing weeds. A mixture of both can simultaneously control weed seeds and existing weeds in the soil, significantly improving weed control efficiency. Therefore, farmers often mix pre-emergent herbicides with glyphosate-based products in actual pest control. However, due to differences in adjuvant systems, stratification and precipitation often occur during the mixing process. This article selects 42% S-metolachlor, isoxaflutole, and atrazine SE, which has shown excellent pre-emergent effects in cornfields, for mixing.

[0131] Test method: Prepare a 50-fold dilution of each sample with distilled water (or tap water). Prepare a 50-fold dilution of 42% S-metolachlor·isoxachlor·atrazine SE with distilled water (or tap water). Mix 100 ml of each sample's 50-fold dilution with 100 ml of the 42% S-metolachlor·isoxachlor·atrazine SE dilution. Place the mixture in a 250 ml graduated cylinder and let it stand at room temperature for 1 hour before observation.

[0132] Table 4 Results of the mixing test with pre-emergent herbicides

[0133] deal with Dilute 50 times, 1 hour Preparation Example 1 No layering, no sedimentation Preparation Example 2 No layering, no sedimentation Preparation Example 3 No layering, no sedimentation Preparation Example 4 No layering, no sedimentation Preparation Example 5 No layering, no sedimentation Preparation Example 6 No layering, no sedimentation Compare with Example 1 No layering, no sedimentation Compare with Example 2 Precipitation Compare with Example 3 Layering Compare with Example 4 Precipitation

[0134] Table 4 shows that no stratification or precipitation occurred when the prepared examples (Preparation Examples 1 to 6) were mixed with the pre-emergent herbicide. The prepared examples of this invention used coconut oil amine polyoxyethylene ether quaternary ammonium salt, dodecacarbonyl alcohol polyoxyethylene ether, and C8-C... 10 The mixture of alkyl polysaccharides serves as a surfactant, and the synergist ammonium sulfate is added to prevent the mixed drugs from separating or precipitating, thereby expanding the scope of application of the formulation.
