4-iodophenoxyacetic Acid 3-indoleacetic Acid(iaa)

4-Chlorophenoxyacetic acid and 3-indoleacetic acid (IAA) are both plant growth regulators, and their functions are crucial in agriculture and horticulture.
4-chlorophenoxyacetic acid is mainly used to prevent flowers and fruits from falling and improve the fruit setting rate. In tomato and other fruit and vegetable planting, treating flowers with a suitable concentration of 4-chlorophenoxyacetic acid solution during the flowering period can effectively avoid the phenomenon of falling flowers caused by physiological factors, help fruits set smoothly, and then increase yield. And it also plays a role in promoting fruit enlargement, which can make fruits develop more fully and enhance commodity value. In addition, to a certain extent, it can also affect the growth form of plants, adjust the nutrient distribution of plants, and make nutrients flow more to the fruit parts.
3-Indoacetic acid, or IAA, is a naturally occurring auxin in plants. It has a wide range of effects on plant growth and has a significant effect on cell elongation. In the seedling stage, it can promote the elongation and growth of stems, roots and other organs, so that plants can thrive. At the same time, IAA plays a key regulatory role in the phototropism and geotropism of plants. When plants are irradiated by unilateral light, IAA will be more distributed on the backlit side, promoting faster cell elongation on the backlit side, so that plants can grow curved to light; under the action of gravity, the distribution change of IAA in roots will lead to root-to-ground growth and stem-to-dorsal growth. Furthermore, IAA is also involved in the regulation of plant lateral bud growth, and high concentrations will inhibit lateral bud germination and maintain the top dominance of plants.

4-Chlorophenoxyacetic acid and 3-indoleacetic acid (IAA) are widely used in the field of agricultural mulberry, and have many effects.
4-chlorophenoxyacetic acid is often used as a plant growth regulator. First, it can protect flowers and fruits. During the flowering period of fruits and vegetables, applying this substance can prevent flowers and fruit shedding, and greatly increase the fruit setting rate. For example, when tomatoes bloom, dip 4-chlorophenoxyacetic acid solution at an appropriate concentration into the flowers, the fruit can be stable and abundant. Second, it can promote fruit expansion. When used in the development of fruit, it can speed up fruit growth, make fruit shape positive, increase fruit size, and increase yield. And can improve the quality of fruit, increase its sweetness and taste. Furthermore, it can prevent the growth of vegetables. When leafy vegetables grow, proper application can regulate their growth rhythm, make leaves thick and improve quality.
3-indoleacetic acid is an endogenous hormone in plants and has many wonderful uses. It can promote root growth. When plant cuttings propagate, dip the base of the cuttings in a solution containing 3-indoleacetic acid, which can stimulate the cuttings to produce new roots, speed up rooting, increase the number of roots, and improve the survival rate of cuttings. In the seedling stage, the root system can be developed, the soil can be deeper, and the plant's ability to absorb nutrients and water can be enhanced. Second, regulate plant growth. It can promote the elongation of stems, coordinate the growth of above-ground and underground parts of plants, and make plants grow sturdy. When flower buds differentiate, it also has the function of regulation, or can promote the formation of flower buds, increase the amount of flowers, and lay the foundation for the result. And it can participate in physiological processes such as plant phototropism and geotropism, and help plants adapt to changes in the external environment.
Both are used in farming mulberry affairs, either alone or in combination with others, and are good agents for increasing harvest and improving quality, and are of great benefit to farming.

Both 4-chlorophenoxyacetic acid and 3-indoleacetic acid (IAA) are plant growth regulators, each of which has a unique mechanism of action in the growth and development of plants.
First, 3-indoleacetic acid, which is a naturally occurring auxin in plants, plays a huge role in the elongation of plant cells. Cover IAA can acidify the plant cell wall, weaken the hydrogen bond between the fibers of the cell wall, cause the cell wall to relax, and the osmotic pressure in the cell makes the cell absorb water and elongate. And IAA also has a key effect on the maintenance of plant apical dominance. The IAA produced by the shoot tip is transported downward polarity, accumulates in the lateral buds, inhibits the growth of lateral buds, and makes the main stem of the plant grow vigorously, and the growth of lateral branches is inhibited. In the development of plant roots, low concentrations of IAA can promote the elongation of taproot, while high concentrations inhibit it; and it can also induce and regulate the formation of adventitious roots and lateral roots.
As for 4-chlorophenoxyacetic acid, its mechanism of action is different from IAA. 4-chlorophenoxyacetic acid mainly affects the growth and differentiation process of plants. When plants bloom and bear fruit, it can promote ovary enlargement and induce parthenogenous fruiting, so that fruits can develop into fruits without fertilization, and can prevent flower and fruit falling, and improve fruit setting rate. In the field of tissue culture, 4-chlorophenoxyacetic acid can regulate the formation and differentiation of callus, induce dedifferentiation of plant cells to form callus, and guide callus to re-differentiate into roots, buds and other organs at appropriate concentrations.
Although both affect plant growth, IAA mostly focuses on the natural regulation of plant growth and development, such as cell elongation, apical dominance and root development; 4-chlorophenoxyacetic acid is more used to artificially regulate plant flowering and tissue culture to meet the specific needs of agricultural production and plant research.

4-Chlorophenoxyacetic acid and 3-indoleacetic acid (IAA) are both plant growth regulators, but their chemical structures are different, and their roles and safety in plants are also different.
4-chlorophenoxyacetic acid is often used as a flower and fruit preservative. It can effectively prevent flowers and fruits from falling, improve fruit setting rate, and promote fruit enlargement. It is widely used in tomato, eggplant and other vegetable and fruit cultivation. However, its safety needs to be carefully considered. If the dosage exceeds the specified range, it may cause deformity of fruits and vegetables, affecting fruit quality. And excessive residues in fruits and vegetables, enter the human body through the food chain, accumulate for a long time or endanger human health, such as interfering with the endocrine system. Therefore, when using, it must be operated according to the specified dose and method, and the use period and frequency must be strictly controlled to reduce the risk of residue.
3-indoleacetic acid is an endogenous hormone in plants, which plays a key regulatory role in many aspects of plant growth and development, such as cell elongation, division, rooting, germination and flowering. Because it is produced by plants themselves, it has a mild and natural regulatory effect on plant growth within the normal concentration range, and is relatively safe. In agricultural production, rational use can promote plant root development and enhance plant stress resistance. But even so, if used improperly, such as high concentration, it will also have negative effects on plant growth, such as inhibiting root growth and causing leaf curl.
In conclusion, although 4-chlorophenoxyacetic acid and 3-indoleacetic acid can regulate plant growth, they should be used with caution. For different plants, growth stages and expected effects, precise control of dosage and method of use can ensure the healthy growth of plants, and at the same time ensure the safety of agricultural products and human health.

In today's world, it is difficult to determine the price of 4-chlorophenoxyacetic acid and 3-indoleacetic acid (IAA) in the market. The change in the price of the two depends on many reasons, and their prices are constantly changing and very fixed.
4-chlorophenoxyacetic acid has a wide range of uses. In agriculture, it can be used as a plant growth regulator to help the growth of fruits and vegetables, and to protect flowers and fruits. Its price depends on the supply of raw materials, the cost of production, and the needs of the market. If the raw materials are abundant and easy to produce, and the demand is flat, the price may be stable and appropriate; however, if the raw materials are scarce, the cost of production will increase, and the demand will be prosperous, the price will rise.
3-Indole acetic acid is also an important plant growth regulator, which is useful in the process of plant rooting, germination, flowering, and fruiting. The change of its price also follows the principle of supply and demand. When there are many producers, the supply exceeds the demand, and the price will drop by itself; if there are few producers, the demand cannot be obtained, and the price will rise.
Looking at various markets, the price range may vary depending on time, place, and quality. Or in a city, the price of the better quality is high, and the price of the second is low; or if you are in a hurry, the price will rise, and if it is slow, it will fall. And the difference in places also makes the price different. The price of those far from the origin may be high, and the price of those near it may be flat.
However, if you want to know the exact price, you should go to the city in person, consult the merchants, or check the price situation in the e-commerce platform, and then you can get the real-time price, so that the user can participate.
