Description

 TECHNICAL FIELD The present invention relates to the field of contact-type chemical herbicide compositions, and more particularly to a herbicide composition for controlling weeds such as water weeds, rice grass and the like. Background Art Water hyacinth is a multi-year aquatic plant native to South America, which has a strong asexual reproduction ability, and its population has a maximum daily reproduction rate of 20-30%. Water hyacinth and rice grass are the main aquatic plants polluting and obstructing waterways in southern China. They multiply and float on the water surface, reducing the ability of light to penetrate water bodies, causing the water environment to deteriorate, aquatic organisms to decrease, and blocking river channels to hinder shipping. . Due to its strong reproductive ability, herbicides are often used to control the damage of aquatic plants. The commonly used herbicides are paraquat and glyphosate. Paraquat is a contact herbicide that can quickly kill the parts that come into contact with the drug, but cannot be eradicated. Moreover, paraquat is more toxic and has an adverse effect on aquatic organisms after spraying. Glyphosate is a systemic non-selective herbicide that mainly inhibits the synthesis of certain synthetase in plants by leaf and diameter absorption, which interferes with protein synthesis and leads to the death of weeds. However, due to the rapid growth rate of water hyacinth and rice grass, and belonging to aquatic plants, the fresh water plants can still cover the original water body after the water plants are sprayed, and the water hyacinth and rice grass cannot be completely killed. The main aquatic plant that breeds fast.

化学名称为 1， 1-二甲基 -4， 4-联吡啶阳离子盐。 百草枯为速效触杀型灭生性除草剂， 采 用茎叶喷雾法施药。 施药后， 药液中联吡啶阳离子迅速被植物茎、 叶片吸收， 在绿色组 织中通过光合和呼吸作用被还原成联吡啶游离基， 又经自氧化作用使茎、 叶组织中的水 和氧形成过氧化氢和过氧游离基， 这类物质对叶绿体层膜破坏力极强。 Paraquat is also known as gramless, hundred, and its molecular structure is:

The chemical name is 1,1-dimethyl-4,4-bipyridyl cation salt. Paraquat is a quick-acting contact-killing herbicide that is applied by stem and leaf spray. After application, the bipyridyl cation in the drug solution is quickly absorbed by the stems and leaves of the plant, and is reduced to the bipyridyl radical by photosynthetic and respiration in the green tissue, and the water and oxygen in the stem and leaf tissue are autooxidized. The formation of hydrogen peroxide and peroxy radicals, such substances have a strong destructive effect on the chloroplast film.

 Glyphosate (glyphosate), also known as Nongdele, Nongda, Zhencao Ning, generally used glyphosate acid, glyphosate isopropylamine salt, glyphosate methylamine salt, glyphosate ammonium salt, grass Gan Phosphine sodium salt or glyphosate potassium salt. The molecular structure of glyphosate acid is:

 Glyphosate mainly inhibits the conversion of valerin to phenylalanine, tyrosine and tryptophan by inhibiting the enol acetone-based valerin phosphate synthase in plants, causing the synthesis of proteins to interfere with plant death. Glyphosate is famous for its strong internal conductivity. It can not only be transmitted to the underground part through stems and leaves, but also can be transmitted between different branches of the same plant. It has strong destructive power to the underground tissues of perennial deep root weeds. It reaches the depth that cannot be achieved by general agricultural machinery. Glyphosate has a wide spectrum of herbicides and has a protective effect on more than 40 species of plants, including monocotyledonous and dicotyledonous, perennial and perennial, herbaceous and shrub plants. Some plants of Leguminosae and Liliaceae are more resistant to glyphosate. After glyphosate enters the soil, it quickly loses its activity by binding to metal ions such as iron and aluminum.

 The common name of "Nongyoufa 41" is 41% glyphosate isopropylamine saline. It is a herbicide-inducing stem-leaf herbicide that is absorbed into the whole plant by the green part of the plant. Root kills. Has a superior weeding effect. This product is mainly used in land crop herbicides such as tea gardens, orchards and rubber gardens, and can control almost all annual and perennial weeds. Zhejiang Linghua Group Co., Ltd. and many companies in Sichuan Province have produced.

 Hydrogen peroxide is an inorganic oxidant, has strong oxidizing properties, can generate a large amount of heat energy in combination with light, and has strong burning corrosion to the leaves and diameters of plants, and can be quickly burned after being sprayed onto the surface of aquatic plants. Burning, corroding leaves, waxy protective film on the surface of the surface and infiltrating into the interior of the plant to destroy the chloroplast. Hydrogen peroxide can also make up for the deficiency of paraquat in the formation of hydrogen peroxide in aquatic plants, and cause greater damage to the chloroplasts in the leaves and diameter tissues of water plants, and accelerate the killing of leaves and trails of water plants such as water hyacinth and rice grass. Dead speed.

Aluminum sulfate, molecular formula A1 ₂ (S0) ₃ , X3⁄40, commonly used in sewage purification, it can complex with toxic molecules or heavy metal substances in the herbicide after contact to form macromolecular precipitation, effectively reduce the toxicity of herbicides, prevent Herbicides contaminate water bodies. The aluminum sulfate in the herbicide may also be an aluminum salt for purifying water such as polyaluminum sulfate or polyaluminum chloride. Anhydrous sodium sulfate, also known as anhydrous thenardite, has a molecular formula of Na ₂ S0 ₄ , is easily soluble in water, and is beneficial for diarrhea and detoxification. In the present herbicidal composition, sodium sulfate can rapidly promote the dehydration of leaves and tissue after corrosion and corrosion initiation, and enhance the killing effect of the active ingredient.

Magnesium sulfate, the molecular formula is MgS0 ₄ , 73⁄40, soluble in water, can be used as laxative and dehydration. It has the same effect as sodium sulfate in the herbicide, and can also act as an adhesive agent, increasing the active ingredient. The adhesion of the surface of the plant.

 The penetrant JFC is a fatty alcohol polyoxyethylene ether surfactant, also known as Indomethacin, a wetting agent JFC, an industrial penetration and sizing agent for fabrics, a leather coating penetrant, and the like. The component can change the hydrophilic and lipophilicity of the herbicide. When the dilution of the herbicide is sprayed on the surface of the water hyacinth and the like, the surface does not condense into water droplets on the surface, thereby forming a water film to fully cover the leaves of the water grass. The surface of the surface is maximized. At the same time, when the active ingredient begins to corrode the internal tissues of the leaves and the diameter, the penetrant JFC can also act as an infiltration to promote the full and rapid exertion of the drug. ,

 Paraquat has a strong vomiting odor, the taste of the spray operator is difficult to bear, and the herbicide mixture prepared from paraquat, licorice, hydrogen peroxide, aluminum sulfate, magnesium sulfate, sodium sulfate and penetrant JFC The color is purple, and the color is a warning color. In order to change the influence of the odor of the herbicide, other fragrance materials such as industrial mint essence may be added to the herbicide mixture to adjust the odor; and in order to eliminate the adverse effect of the color of the herbicide liquid, an appropriate amount of the organic dye amaranth may be added. And, make the herbicide mixture present a noble black. The molecular formula of amaranth is C HuNaNasC oS^ It is an acid dye and the aqueous solution is amaranth.

 The active ingredients of the herbicide, paraquat, glyphosate and hydrogen peroxide, can form a coating film on the smooth leaves and radial surfaces of water plants such as water hyacinth under the action of penetrants JFC and magnesium sulfate, and have strong adhesion and peroxidation. Hydrogen can burn the protective film on the surface of the leaf surface in a very short or even a few seconds, so that paraquat and glyphosate can destroy and corrode the internal tissues of water plants such as water hyacinth, while magnesium sulfate and sodium sulfate can accelerate The dehydration and death of the leaf-path tissue can also make the effect of the active ingredient more obvious. The hydrogen peroxide component remaining after the herbicide kills the water grass decomposes rapidly under the action of light energy, leaving no harmful substances. Aluminum sulfate can complex the harmful substances formed by weeding herbicides to form precipitates, which will not pollute the waters sprayed, and will not cause any harmful effects on aquatic organisms. It has good environmental protection functions.

Most herbicides on the market use paraquat or glyphosate as active ingredients. For example, the herbicide of the company Monsanto produces the name "Nongda", which uses about 40% of glyphosate isopropylamine as an active ingredient. Zhejiang Linghua Group Co., Ltd. produces the product name "Nongyoufa 41" herbicide, which uses about 41% of glyphosate isopropylamine salt as the active ingredient; the trademark produced by Syngenta (China) Investment Co., Ltd. The herbicide is named "Kn't Trace" and it uses about 20% paraquat cation as an active ingredient. Paraquat and glyphosate in the herbicide can be replaced by the same concentration of the above finished herbicide. Thanks to 20°/. Paraquat solution is corrosive to ordinary metals, glyphosate is plated on metal Zinc containers have a corrosive effect and are prone to fires. Therefore, metal utensils should be avoided during storage and preparation. However, the diluted herbicide spray solution has no corrosive effect on the metal parts of the sprayer.

 Most of the raw materials used in the herbicide are aqueous solutions of a certain concentration, so the dilution ratio of the spraying operation is relatively small. The ratio of the general chemical liquid to the watering is 1:40-60, and the spraying density is about 2000 ml of the original liquid/mu water area.

The invention has the beneficial effects of using paraquat, glyphosate and hydrogen peroxide as main active ingredients, combined with the adhesion of the penetrant and JF magnesium sulfate, and the dehydration of magnesium sulfate and sodium sulfate, and can adhere to the water hyacinth, etc. The surface of the leaf surface of the aquatic plant quickly exerts its potency, and in a short period of time, it can completely kill water plants such as water hyacinth and rice grass, effectively preventing the spread of harmful aquatic plants; in addition, the aluminum sulfate in the herbicide can be used for weeding. The harmful substances after weeding act as a complex precipitation, which can minimize the negative impact of herbicides on the sprayed waters, and has a good environmental protection effect. The herbicide can be widely used in various waters for the killing and removal of grasses mainly composed of water hyacinth and rice grass. EXAMPLES OF THE INVENTION The present invention will be further illustrated by the following specific examples. In order to illustrate the effects of the present invention, we used a "Nongda" herbicide and a "Nongyoufa 41" herbicide to control the herbicidal effects of water hyacinth, rice grass and the like with the same Examples 1-4. However, the invention is not limited to these embodiments. Example 1 Environmentally-friendly fast heat-osmotic double-contact herbicide, using the following raw materials ratio, 17 parts by weight of 20% paraquat solution (manufactured by Monsanto, USA), 38 parts by weight of 41% glyphosate isopropylamine salt solution (Zhejiang Linghua Group Co., Ltd. product "Nongyoufa 41"), 33 parts by weight of 30% hydrogen peroxide solution (commercially available, industrial grade), 3 parts by weight of 2% aluminum sulfate solution (commercially available, industrial grade), 2 parts by weight of 7% magnesium sulfate solution (commercially available, industrial grade), 4 parts by weight of 9% sodium sulfate solution (produced by Sichuan Meishan Glauber's Salt Co., Ltd.) and 2 parts by weight of penetrant JFC (produced by Shanghai Auxiliary Research Institute) The preparation method comprises the steps of: placing the paraquat solution, the glyphosate solution and the hydrogen peroxide solution into a sealed plastic container with a stirrer, mixing and stirring uniformly, and then adding a sodium sulfate solution, a magnesium sulfate solution, an aluminum sulfate solution; The herbicide is prepared by mixing with the penetrant. Example 2 Environmentally friendly fast thermal infiltration double contact herbicide, using the following raw material ratio, 20 parts by weight of 20% paraquat solution, 45 parts by weight of 41% glyphosate acid solution, 40 parts by weight of 30% hydrogen peroxide Solution, 5 parts by weight of 2% aluminum sulfate solution, 5 parts by weight of 7% magnesium sulfate solution, 6 parts by weight of 9% sodium sulfate solution, 3 parts by weight of penetrant JFC, 0.1 parts by weight of mint flavor (Hangzhou Produced by Knight Fragrance & Fragrance Co., Ltd.) and 0.1 part by weight of organic dye amaranth (produced by Shanghai Dyestuff Fuel Research Institute).

Evenly mixing, then using peppermint essence to adjust the odor of the mixture, and adjusting the color of the mixture with the organic dye amaranth to obtain the herbicide.

 Applicants sent the herbicides prepared in Example 1 and Example 2 to the Fujian Provincial Analytical Testing Center for the detection of toxic and hazardous substances. The detection methods are as follows:

 GB/T 7486-1987 Determination of water cyanide

 GB/T 15337-1994 Determination by atomic absorption spectrometry

 GB/T 7492-1987 Determination of water quality of six six six, DDT

 GB/T 8538-1995 Test method for drinking natural mineral water 33 arsenic atomic fluorescence method cold atomic absorption spectrophotometry

 Example 1 and Example 2 The test results of the herbicide are the same, and the test data are shown in Table - Table 1. Test results of various toxic and hazardous substances in the herbicide

由表一可以看出， 本环保型快热渗双触杀除草剂除氰化物含量较高外， 其与有害物 质均远远低于国家食品卫生标准中的有毒有害含量。 并且， 本除草剂中的氰化物应该可 以确定大部分成分是亚铁氰化钾， 亚铁氰化钾在食盐中作为抗结剂使用， 不能认为该氰 化物为无机剧毒品中的氰化钾、 氰化钠或氰酸钠等类物质。

It can be seen from Table 1 that the environmentally-friendly fast-heating double-contact herbicide has a high content of cyanide, and its harmful substances are far lower than the toxic and harmful content in the national food hygiene standards. Moreover, the cyanide in the herbicide should be able to determine that most of the components are potassium ferrocyanide, and potassium ferrocyanide is used as an anti-caking agent in salt. It cannot be considered that cyanide is cyanide in inorganic drugs. Potassium, sodium cyanide or sodium cyanate.
