Efficacy and characteristics:

It promotes plant cell elongation and division and is an auxin necessary for plant growth. It promotes rooting and plays a key role in cutting propagation and plant root development. It regulates the growth direction of plants, such as phototropism and geotropism.

Precautions:

Indoleacetic acid is easily decomposed under light, so after use, try to avoid strong light exposure to plants, or choose to use it in the evening when the light is weak. Different plants react differently to indoleacetic acid, and the concentration needs to be adjusted according to the plant species and growth stage. Indoleacetic acid should be stored away from light and at low temperatures to prevent its decomposition and ineffectiveness.

Efficacy and characteristics:

Promotes plant leaf shedding, used before cotton and other crops are harvested, and is convenient for mechanical harvesting. It promotes plant cell division and elongation, and also has a certain effect on fruit enlargement. Enhances plant resistance and reduces environmental stress damage to plants.

Precautions:

When thiazuron is used to defoliate crops such as cotton, pay attention to the time of use. It should not be used too early or too late, otherwise it will affect the yield or defoliation effect. It is irritating to the human body, so take good protection during use.
When thiazuron is mixed with other pesticides or fertilizers, precipitation, discoloration and other phenomena may occur, and compatibility needs to be paid attention to.

Efficacy and characteristics:

Promotes plant seed germination and rooting, and improves seed germination rate. Enhances plant photosynthesis, makes plants grow strong, and increases crop yields. Improves plant resistance and maintains plant growth in adverse environments.

Precautions:

Triacontanol may be effective with a small amount, so the dosage must be accurately controlled to avoid waste and pesticide damage. It should be used in sunny weather, which is conducive to plant absorption. Rainy days may affect the effect.
When it is mixed with other regulators or fertilizers, synergistic effects may occur, which requires advance testing.

Efficacy and characteristics:

Induce plant disease resistance, activate the plant’s own defense system, and resist fungal, bacterial and other diseases. Promote plant growth, increase plant chlorophyll content, and improve photosynthesis efficiency. Improve soil environment and promote the growth and reproduction of beneficial microorganisms in the soil.

Precautions:

The quality of chitosan oligosaccharide varies greatly. When using it, pay attention to the pH value of the solution. It can work better within the appropriate pH range.
Chitosan oligosaccharide is best used during the critical period of plant growth (such as transplanting period and early stage of disease) to enhance plant resistance.

Efficacy and characteristics:

Used to promote plant rooting, and has better effects on some plant varieties that are difficult to root. When used as a herbicide, it can kill dicotyledonous weeds at high concentrations and is used for weeding in the fields of gramineous crops.
Preventing flowers and fruits from falling, it has a certain fruit-preserving effect in the cultivation of fruit trees such as citrus.

Precautions:

When 24-D is used as a herbicide, it is necessary to strictly distinguish between dicotyledonous and monocotyledonous plants to prevent pesticide damage to crops. When used to prevent flowers and fruits from falling, too high a concentration may cause fruit deformity, and the concentration must be accurately controlled.
During the operation, pay attention to prevent the agent from drifting and causing damage to surrounding non-target plants.

Effects and characteristics:
Induce plants to produce systemic acquired resistance to pathogen invasion, such as tobacco’s resistance to tobacco mosaic virus. Regulate the opening and closing of plant stomata to help plants reduce water loss during drought. Participate in the growth and development of plants, such as seed germination and root growth.

Precautions:
Salicylic acid may be toxic to plants at high concentrations, so it should be used strictly according to the recommended concentration. The effects of salicylic acid may be affected by environmental factors (such as temperature and humidity), so these factors should be considered when using it. Its metabolic process in plants is relatively complex, and excessive use may interfere with the normal physiological metabolism of plants.

Effective features:
Shorten internodes, short and strong plants, prevent leggy growth in corn planting. Increase lodging resistance and drought resistance of plants, improve crop survival ability. Promote reproductive growth, conducive to flower bud differentiation and fruit development.

Precautions:
The concentration of chlormequat should be accurate. Different plant varieties have different sensitivities to it. Too high a concentration will stagnate plant growth. Pay attention to the use period. It is generally used in the early stage of plant growth to inhibit vegetative growth and promote reproductive growth. It cannot be mixed with alkaline pesticides, otherwise the efficacy will be reduced.

Efficacy and characteristics:
Promote fruit ripening, used for ripening bananas and other fruits, so that they can be put on the market earlier. Promote the shedding of plant organs, such as promoting the shedding of leaves before cotton harvest to facilitate picking. Induce the formation of female flowers, which is used in the cultivation of melon crops such as cucumbers.

Precautions:
Ethephon is toxic to the human body, so wear protective equipment when using it. When used for ripening, the appropriate use time and concentration should be determined according to the degree of maturity of the fruit and the characteristics of the variety, otherwise it may lead to a decline in fruit quality, such as poor taste and poor storage resistance. Ethephon will decompose rapidly when it encounters alkaline substances and cannot be mixed with alkaline pesticides or fertilizers.

Effects and characteristics:
Inhibit the vegetative growth of plants, dwarf the plants, and control the plant shape in flower planting.Promote the differentiation of flower buds in plants, increase the number of flowers, and increase the yield of fruit trees.Enhance the resistance of plants to lodging, such as reducing lodging in wheat growth.

Precautions:
Paclobutrazol has a long-lasting effect. The soil residue after use may affect the subsequent crops, so pay attention to the reasonable arrangement of the order of planting crops. Strictly control the amount of use. Excessive use will cause serious stunting of plant growth, too short plants, and wrinkled leaves.Generally used in the vigorous growth period of plants, avoid using it in the weak growth period of plants to aggravate the adverse effects.

Parachlorophenoxyacetic acid, also known as anti-drop agent, is a phenolic plant growth regulator.

Efficacy and characteristics:

It is mainly used to prevent flowers and fruits from falling. It is used in the cultivation of tomatoes and other solanaceous vegetables to increase the fruit setting rate. It promotes fruit development and makes the fruits uniform in size and regular in shape.

Precautions:

Anti-drop agent is mainly used to prevent flowers and fruits from falling. When using it, pay attention to the exact time of flowering and fruiting. Too early or too late may not achieve the expected effect. Improper concentration control may lead to deformed fruits. Different fruit tree varieties have different suitable concentration ranges. Pay attention to uniformity and thoroughness when spraying, especially on flowers and young fruits.
