It is a widely used plant growth regulator. Its main function is to slowly inhibit the division of the thin thorax at the bottom of the top of various crops, resulting in thick stems, shortened internodes, shorter plants, well-developed root systems, wider and thicker leaves, darker green leaf color, and no deformity of flowers, leaves and later growth. Dwarfine can be used in most food and economic crops, vegetables, etc., such as corn, rice, tobacco, potatoes, tomatoes, etc., and has a good yield-increasing effect. For cotton, apply a secondary spray of 20-50mg/L of the agent at the bud and boll stage. For wheat, use a 0.15% - 0.3% solution of the agent and soak the seeds for 6-12 hours. Spray 50% water-based solution at a dilution of 200 to 500 times on sorghum, rice, soybeans, tomatoes, etc. during the appropriate period.
Plant hormones are several types of trace organic substances synthesized in plants, which have significant regulatory effects on plant growth, development and metabolism. Also known as plant natural hormones or plant endogenous hormones. It includes five types: auxin, gibberellin, cytokinin, abscisic acid and ethylene. Auxin is the earliest discovered and most studied plant hormone. Indoleacetic acid (abbreviated as IAA) is the auxin that is widely present in plants and has the strongest physiological activity. Ethylene is a kind of unsaturated hydrocarbon with a very simple chemical structure, which is widely present in various plant tissues, especially in mature fruits and withered flowers where it has a relatively high content. When plants are subjected to stress damage, the formation of ethylene in the tissues increases significantly. In addition to the above five types of plant hormones, more than ten kinds of steroidal physiologically active substances were purified from plants in the 1970s. Among them, brassinolide has the strongest physiological activity, and some people believe it is a new type of plant hormone.
It is a broad-spectrum plant growth regulator. It can promote cell division and expansion, induce the formation of adventitious roots, increase fruit setting, prevent fruit drop, and change the ratio of female to male flowers, etc. Naphthylacetic acid can enter the plant body through the tender epidermis of leaves and branches and seeds, and be transported to the action site along with the nutrient flow. It is usually used for wheat, rice, cotton, tea, mulberry, tomato, apple, melon, potato, forest tree, etc., and is a good plant growth stimulant. When used to prevent fruit drop, the concentration should not be too high; otherwise, it may have the opposite effect, as high concentrations of naphthalene acetic acid can promote the production of ethylene in plants. When used for root promotion, it is advisable to mix it with indoleacetic acid or other agents that have root-promoting effects. Although the root-promoting effect of crops is good when naphthalene acetic acid is used alone, the growth of seedlings is not ideal. When spraying fruits and melons, it is advisable to evenly wet the leaf surface. For field crops, the general spraying amount of the liquid is about 7.5kg per 100 square meters, and for fruit trees, it is 11.3 to 19kg per 100 square meters. Treatment concentration: For fruits and melons, spray 10 to 30mg/L; for wheat, soak the seeds at 20mg/L for 6 to 12 hours; for cotton, spray 2 to 3 times during the full flowering period at 10 to 20mg/L. This product can be mixed with common insecticides, fungicides and fertilizers. The effect is better on sunny days without rain.

Plant growth regulators are artificially synthesized organic compounds with physiological activity, similar to plant hormones, and capable of regulating the physiological processes of plants, controlling their growth and reproduction. Indolebutyric acid (IBA) and naphthylacetic acid (NAA) are two commonly used plant growth regulators for cuttings and root growth, among which indolebutyric acid has the best effect because it moves less within the plant body. It is easy to remain near the part of use. Furthermore, if Chemicalbook mixes one root growth regulator with another substance that is conducive to the effect of the growth regulator, it can show enhanced or synergistic effects, which may lead to more satisfactory results for plants that are difficult to root. Indolebutyric acid has a strong root-promoting effect, but it produces fine and long adventitic roots. In contrast, naphthylacetic acid (NAA) has a root-promoting effect with fewer and thicker roots. Therefore, when the two are used in combination, better results are often achieved.
It is used as a plant growth stimulant and analytical reagent. 3-indoleacetic acid and auxin substances such as 3-indoleacetaldehyde, 3-indoleacetonitrile and ascorbic acid exist naturally in nature. The precursor of 3-indoleacetic acid biosynthesis in plants is tryptophan. The fundamental function of auxin lies in regulating plant growth. It not only promotes growth but also has the effect of inhibiting growth and organ formation. In plant cells, auxin not only exists in a free state but also can be firmly bound to biomolecules and other substances in the form of bound auxin. There are also auxin that form complexes with special substances, such as indole-acetylasparagine, indole-acetic acentose, and indole-acetylglucose, etc. This might be a way for auxin to be stored within cells and also a detoxification method to eliminate the toxicity of excessive auxin.

Compared with sodium and potassium glyphosate salts, ammonium glyphosate salts have the advantages of being less prone to caking, having lower manufacturing costs and higher herbicidal activity. Monsanto Corporation of the United States developed a glyphosate ammonium salt soluble granule agent (SG), which was mass-produced in 1993. After screening, the Mon44068 adjuvant was finally selected for this dosage form. Its most prominent feature is that it significantly reduces toxicity to mammals and water, and it also has high herbicidal activity. This dosage form is a dust-free extruded granule with an average bulk density of 1.45kg/ L. It can rapidly disintegrate into a solution under a wide range of different temperatures and concentrations in reference water conditions (soft water or hard water). Meanwhile, it retains the convenience of liquid dosage form use and the ease of handling in packaging containers (can be packed in paper bags). At the beginning of this century, the first commercialized product launched by the company in the Chinese market was the "747 Farmer's Joy" ChemicalbookSG. It is a soluble granulation agent containing 74.7% ammonium glyphosate salt, 20% additives and excipients. It appears as light yellow or pale yellow granules with a particle size of 1 to 3mm. When put into water, it can dissolve rapidly and the solution is slightly acidic. Because this product has low toxicity, is solvent-free and dust-free, it became a new product that farmers welcomed and loved at that time. In China, Xin 'an Group Company has developed the first glyphosate ammonium salt soluble granule agent "Nongwang 757SG", which contains 75.7% glyphosate ammonium salt. At present, there are also higher concentration products of glyphosate ammonium salt soluble granules developed in China, such as 80% and 88.8%, etc. The main purpose is to reduce costs and inventory. In terms of the current quality of glyphosate ammonium salt soluble granules both at home and abroad, domestic products may still have a certain gap compared with similar foreign products, mainly reflected in the quality and dosage of the additives used.
