DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] An embodiment provided by the present invention is a compound herbicide formula for Mikania micrantha, characterized in that it comprises: dipentene, glyphosate, a penetrant, ethanol, and urea.

[0024] Dipentene accounts for 30%, and glyphosate accounts for 10%. Dipentene limonene, also known as limonene, dipentene, and 1,8-terpenadiene, is an organic compound with a chemical formula of C10H16. It is a natural functional monoterpene, mainly used as a solvent, and can also be used in organic synthesis. It is mainly used as a solvent and can also be used in organic synthesis. Glyphosate, with a chemical name of N-(phosphomethyl)glycine and a chemical formula of C3H8NO5P, is an organophosphine herbicide and a systemic broad-spectrum lethal herbicide. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer published a preliminary list of carcinogens. For reference, glyphosate is on the list of Class 2A carcinogens. Glyphosate is a non-selective, non-residue herbicide that is very effective against perennial root weeds. It is widely used in rubber, mulberry, tea, orchards and sugarcane fields. It mainly inhibits the enzyme enolpyruvyl shikimate phosphate synthase in plants, thereby inhibiting the conversion of shikimate to phenylalanine, tyrosine and tryptophan, disrupting protein synthesis and causing plant death. Glyphosate is absorbed through stems and leaves and then transmitted to various parts of the plant. It can prevent and control more than 40 families of plants, including monocotyledonous and dicotyledonous, annual and perennial, herbaceous and shrubs. After entering the soil, glyphosate quickly reacts with metals such as iron and aluminum. It loses its activity due to ion binding. It was initially used in rubber plantations to control thatch and other weeds, which can enable rubber trees to be tapped one year earlier and increase the yield of old rubber trees. It is now gradually being promoted in forestry, orchards, mulberry gardens, tea gardens, rice-wheat, rice and rapeseed rotation fields, etc. Various weeds have different sensitivities to glyphosate, so the dosage is also different. For annual weeds such as barnyard grass, foxtail grass, alopecuroides, goosegrass, crabgrass, and cleaver, the dosage is 6-10.5g / 100m2 based on the active ingredient; for plantago, Erigeron sphaerocephala, Commelina communis, etc., the dosage is 11.4-15g / 100m2 based on the active ingredient; for Imperata cylindrica, Sclerocaria sinensis, and Phragmites australis, the dosage is 12.4-15g / 100m2 based on the active ingredient. 18-30g / 100m2 is required, which is generally diluted with 3-4.5kg of water. The stems and leaves of weeds should be sprayed evenly and directionally. Generally, broad-leaved weeds should be sprayed in the early germination or flowering stage, and Gramineae should be sprayed in the late jointing or early heading stage. The plants with cut stems and leaves should wait until the weeds have grown enough new leaves before applying the medicine. When preventing perennial weeds, divide the dosage into two times. Applying at intervals of 5 days can improve the prevention effect. It can prevent weeds in apple orchards, peach orchards, vineyards, pear orchards, tea gardens, mulberry gardens and farmland leisure land, and annual weeds such as barnyard grass, oatmeal, goosegrass, crabgrass, Xanthium sibiricum, Chenopodium album, Chickweed, and Glechoma longituba.

[0025] Penetrants are used to help the drug penetrate into plant tissues, and the proportion of penetrants is 10%.

[0026] Ethanol accounts for 20%, and urea accounts for 30%. Ethyl Alcohol, commonly known as alcohol and liquor, is a kind of alcohol compound. Its chemical formula is C2H6O, and its structural formula is CH3CH2OH or C2H5OH. Ethanol has good combustion performance and is a commonly used fuel, solvent and disinfectant. It is widely used in organic synthesis. It uses industrial ethanol as raw material, dehydrates, and then distills in a high-efficiency distillation tower. The finished product can be filtered with a microporous filter membrane. Ethanol is an important basic chemical raw material for the manufacture of acetaldehyde, ethylene, ethylamine, ethyl acetate, acetic acid, ethyl chloride, etc., and derives many intermediates for products such as medicines, dyes, coatings, fragrances, synthetic rubber, detergents, pesticides, etc. There are more than 300 products, but the use of ethanol as an intermediate for chemical products is gradually declining. Many products such as acetaldehyde, acetic acid, and ethyl ethanol no longer use ethanol as raw materials but use other raw materials instead. Danger: volatile, flammable, irritating. Its vapor mixes with air to form an explosive gas. It can burn or explode when exposed to high heat or open flames. It reacts violently with oxidants such as chromic acid, calcium hypochlorite, hydrogen peroxide, nitric acid, silver nitrate, and perchlorates, and there is a risk of combustion and explosion. In a fire scene, heated containers are at risk of explosion. Its vapor is heavier than air and can spread to a considerable distance at a lower level. It will ignite when exposed to open flames. Quickly evacuate personnel from the leaked contaminated area to a safe area, isolate it, and strictly restrict entry and exit. Cut off the source of fire. It is recommended that emergency response personnel wear self-contained positive pressure respirators and fire protection clothing. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drainage ditches.

[0027] The penetrant includes the surfactant sodium dodecyl sulfate and octylphenol polyoxyethylene ether. Octylphenol polyoxyethylene ether is a chemical substance in the form of a light yellow liquid with high chemical stability. It is not easily destroyed by strong acids and alkalis at high temperatures and has poor biodegradability. When n=4, it is easily soluble in oil and organic solvents; when n>7, it is soluble in water at room temperature.
