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 1

[0034] Embodiment 1 The environment-friendly type fast thermal osmosis double-contact herbicide is selected from the following raw material proportions, 12 parts by weight of 20% paraquat solution (produced by Monsanto, U.S.), 20 parts by weight of 35% glyphosate isopropylamine salt solution (Zhejiang Xin'anjiang Chemical Group Co., Ltd.), 25 parts by weight of 30% hydrogen peroxide solution (commercially available, technical grade), 12 parts by weight of aluminum sulfate (commercially available, technical grade), 12 parts by weight of magnesium sulfate (commercially available, technical grade). sales, industrial grade), 12 parts by weight of anhydrous sodium sulfate (produced by Sichuan Meishan Glauber's Salt Co., Ltd.) and 5 parts by weight of penetrant JFC (produced by Shanghai Auxiliary Research Institute), the preparation method is to first paraquat solution, glyphosate Put the phosphine solution and hydrogen peroxide solution into a sealed plastic container with a stirrer...

Embodiment 2

[0035] Example 2 An environment-friendly fast thermal osmotic double-contact herbicide is selected from the following raw material ratio, 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, the aluminum sulfate of 15 parts by weight, the magnesium sulfate of 10 parts by weight, the anhydrous sodium sulfate of 15 parts by weight, the penetrant JFC of 2 parts by weight, the peppermint essence of 2 parts by weight (produced by Hangzhou Knight Flavor and Fragrance Co., Ltd.) and 1 The organic dye amaranth (produced by Shanghai Dyestuff and Fuel Research Institute) of parts by weight.

[0036] 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 Mix, adjust the smell of...

Embodiment 3

[0046] Example 3 Same as Example 1, except that the 20% paraquat solution in the raw material is replaced by "Gewuzong" herbicide produced by Syngenta (China) Investment Co., Ltd., and the 35% glyphosate isopropylamine salt solution is used by Monsanto Company of the United States Produced "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-type chemical herbicide compositions, and in particular relates to a herbicide composition for controlling water hyacinth, ricegrass and other harmful weeds. Background technique [0002] Water hyacinth is a perennial aquatic plant native to South America. It has strong asexual reproduction ability, and the maximum daily reproductive capacity of its population is 20-30%. Water hyacinth and ricegrass are the main aquatic plants that pollute water bodies and block waterways in southern my country. They multiply and float on the water surface, reducing the penetration of light into water bodies, resulting in deterioration of water body environment, reduction of aquatic organisms, and blockage of rivers and obstruction of shipping. . Due to its strong reproductive ability, herbicides are mostly used to control the harm of aquatic plants at present. The commonly used herbicides are paraquat and glyphos...
