Such as pepper blight, tomato blight, etc., in the early stage of blight, rational use of 1-%E6%B0%9F-2-%28%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA%29%E8%8B%AF can prevent the further spread of blight, reduce the infection rate of plants, avoid serious damage to important parts such as fruits, and ensure the quality and yield of agricultural products.
Third, for some other fungal diseases, this medicine also has a certain prevention and control effect. By interfering with the physiological process of pathogenic bacteria, destroying their cell structure or metabolic pathways, enhancing the plant's own resistance, and then achieving the purpose of preventing and treating diseases.
When using, apply the medicine in the form of spray to ensure that the medicine can evenly cover the surface of the plant to give full play to the effect of the medicine. However, it should be noted that the dosage and use method should be strictly followed to avoid pollution to the environment due to excessive use, and at the same time to prevent the generation of pesticides to plants, which will affect the growth and quality of crops.

(1) The property of this substance
1-alkane-2- (trialkyl methyl) benzene is an organic compound. It has the general nature of hydrocarbons and belongs to one of aromatic hydrocarbons.
Looking at its physical properties, under normal conditions, it is mostly liquid, lighter in weight than water, and difficult to dissolve in water, but easily soluble in most organic solvents, such as ether, alcohol, chloroform, etc. Its color is transparent, or slightly light, and it has a special aromatic smell. This smell may be irritating, and it may harm the human body if smelled for a long time.
(2) Boiling point and melting point
The boiling point of this substance varies depending on the molecular structure and relative molecular mass. Generally speaking, compared with similar aromatic hydrocarbons, its boiling point is within a certain range. Due to the fact that the intermolecular forces are mainly van der Waals forces, the structure is relatively complex, resulting in a higher boiling point than simple alkanes. As for the melting point, it is also related to the regularity of the molecular arrangement. Its molecular structure is not extremely regular, so the melting point is not very high, but it can also condense into a solid state at low temperature.
(3) Density characteristics
Its density is less than that of water, which is determined by the combination of atoms in the molecule and the spatial structure. Hydrocarbon substances have this property. The proportion of carbon and hydrogen atoms in the molecule and the binding form make the overall density lower than that of water. In chemical applications and storage, this property is very critical, and it is related to the separation and mixing of substances.
(4) Volatility and stability
have a certain volatility, at room temperature and pressure, can slowly disperse into the air. However, in its chemical structure, benzene ring has special stability, due to the existence of conjugated π bond, its chemical stability is high, and it is difficult to occur addition reaction. However, under specific conditions, such as catalysts, suitable temperature and pressure, substitution reactions can occur, such as halogenation, nitrification, sulfonation, etc., showing its important value as a raw material for organic synthesis.

The chemical stability of 1-% Jiang-2- (trimethyl) silicon depends on many aspects. In this compound, the silicon atom is connected to three methyl groups, which are common groups in organic chemistry and have a certain electron donor effect.
From a structural perspective, the outer electronic structure of the silicon atom allows it to form specific chemical bonds with other atoms. In 1-Jiang-2- (trimethyl) silicon, the silicon-carbon bond is relatively stable, and the electron donor properties of the methyl group affect the electron cloud density around the silicon atom to a certain extent. This makes the compound relatively stable under some common chemical reaction environments.
However, the stability of chemical substances is not absolute. In case of strong oxidizing agents, or under extreme conditions of high temperature and high pressure and the presence of specific catalysts, its chemical properties may change. Strong oxidizing agents can capture the outer electrons of silicon atoms, break the original chemical bonds, and cause structural changes in compounds. High temperature and high pressure environments also increase molecular kinetic energy, making chemical bonds more prone to fracture and recombination.
However, in conventional laboratory conditions and natural environments, 1-Jiang-2- (trimethyl) silicon is usually relatively stable without the intervention of special chemical reagents. Due to its silicon-carbon bond energy and the steric resistance of methyl formation, it can resist the attack of general chemical substances and ensure the relatively constant chemical properties of compounds. Therefore, in general, under common conditions, the chemical properties of 1-Jiang-2- (trimethyl) silicon are quite stable, but under extreme or special chemical conditions, the stability is another matter.

First, the best material is selected. To make this medicine, first look for good quality 1-Jiang-2 - (triethyl) ether, the raw materials must be pure and free, in order to ensure the excellent effect of the medicine. This material should be stored in a clean place, protected from dust, moisture, and light to prevent its quality from changing.
Second, follow the ancient method of processing. First put 1-Jiang-2 - (triethyl) ether in a clean kettle and boil it slowly. In the meantime, the control of the fire is very important. If the fire is fierce, the medicine will be easy to burn, and if the fire is small, it will be difficult to produce. Wait for it to boil slightly, watch its color change, and if there is a clear light, continue to boil for a while. Then, remove the fire, let it cool naturally, and drop to room temperature.
Third, combine with various medicines. Wait for 1-jiang-2- (triethyl) ether to cool, and add other medicines. The medicine prepared is made according to the ancient recipe, with precise proportions, and must not be wrong in the slightest. After mixing the medicines, gently pound them with a wooden pestle to smooth their medicinal properties. After pounding, seal them in a porcelain bottle, place them in a shady place, and wait for the medicinal power to blend. In this way, the best agent of 1-jiang-2- (triethyl) ether can be obtained for medicinal purposes.
