Problems solved by technology

However, due to the rapid reproduction of water plants such as water hyacinth and rice grass, and they are aquatic plants, after the water plants die after spraying, the new aquatic plants can still cover the original water body, and it is impossible to completely kill water hyacinth and rice grass. The main fast-growing aquatic plant

Embodiment 2

[0034] Example 2 An environmentally friendly fast thermal osmosis double contact herbicide, with the following raw material ratios: 10 parts by weight of 20% paraquat solution, 25 parts by weight of 35% glyphosate acid solution, and 20 parts by weight of 30% hydrogen peroxide Solution, 15 parts by weight of aluminum sulfate, 10 parts by weight of magnesium sulfate, 15 parts by weight of anhydrous sodium sulfate, 2 parts by weight of penetrant JFC, 2 parts by weight of peppermint flavor (produced by Hangzhou Knight Flavors and Fragrances Co., Ltd.) and 1 Parts by weight of organic dye amaranth (produced by Shanghai Dyestuff and Fuel Research Institute).

[0035] The preparation method is to first put the paraquat solution, glyphosate solution and hydrogen peroxide solution into a sealed plastic container with a stirrer, mix and stir evenly, and then add sodium sulfate, magnesium sulfate, aluminum sulfate and penetrant evenly After mixing, the odor of the mixed liquid is adjusted wi...

Embodiment 1

[0042] The test results of the herbicides in Example 1 and Example 2 are the same, and the test data are shown in Table 1.

[0043] Test items

[0044] It can be seen from Table 1 that, in addition to the higher content of cyanide, the environmentally friendly fast thermal osmotic double contact herbicide and harmful substances are far lower than the toxic and harmful content in the national food hygiene standards. In addition, the cyanide in this herbicide should be able to determine that most of the components are potassium ferrocyanide. Potassium ferrocyanide is used as an anticaking agent in table salt. It cannot be considered that the cyanide is the cyanide in the inorganic poison. Potassium, sodium cyanide or sodium cyanate and other substances.

Embodiment 3

[0045] Example 3 Same as Example 1, except that the 20% paraquat solution in the raw materials is replaced by the "Ke Wuxian" herbicide produced by Syngenta (China) Investment Co., Ltd., and the 35% glyphosate isopropylamine salt solution is used by Monsanto Produce "Roundup" herbicide instead.

Abstract

The present invention relates to an environment-protecting type quick thermossmosis double-contact weedkiller. Said weedkiller is made up by using paraquat, glyphosate, hydrogen peroxide, aluminium sulfate, magnesium sulfate, sodium sulfate and osmotic agent JFC through a certain preparation process. Said invention also provides its preparation process.

Description

Technical field [0001] The invention belongs to the technical field of contact-killing chemical herbicide compositions, and in particular relates to a herbicide composition for preventing and controlling harmful weeds such as water hyacinth and rice grass. Background technique [0002] Water hyacinth is a perennial aquatic plant native to South America, with strong asexual reproduction ability, and the maximum daily reproduction capacity of its population is 20-30%. Water hyacinth and rice grass are the main aquatic plants that pollute water bodies and obstruct waterways in southern my country. They multiply and float on the water surface, reducing the ability of light to penetrate the water body, causing the deterioration of the water environment, reducing aquatic organisms, and blocking the rivers and hindering navigation. . Due to its strong reproductive ability, herbicides are currently used to control the harm of aquatic plants. Commonly used herbicides are paraquat and glyp...
