What are the growth regulators commonly used in agriculture?

When farmers grow crops, they often use growth regulators, which can promote or control crop growth and development, and now there are many growth regulators commonly used in the market, which play different roles. Through the use of growth regulators, the growth and development of crops can be regulated in time and space, so what are the growth regulators commonly used in agriculture? Let's get to know it next.

1. Compound nitrophenol sodium

The growth regulator can accelerate crop growth, break dormancy, promote growth and development, prevent flower and fruit drop, fruit cracking and fruit shrinkage, improve crop quality, increase yield and improve crop resistance.

The growth regulator is suitable for the application of fertilizers (foliar fertilizer, compound fertilizer, base fertilizer, base fertilizer, etc.). In an environment with suitable temperature, it can be effective in one day, and after use, there is no need to add other similar synergists.

2. Brassinolide

This kind of growth regulator is mainly used for seed soaking and stem and leaf spraying, which can take root, promote growth, raise seedlings, strengthen seedlings, turn green leaves of yellow leaf disease, protect flowers and fruits, promote fruit expansion and early ripening, reduce disease and alleviate drug damage, and coordinate nutritional balance. for the cases of dead seedlings and rotten roots caused by drug damage or diseases, the effect is very significant, and it is very helpful to promote growth and increase production, to a certain extent. It can also delay leaf senescence and improve photosynthesis.

3. Ethephon

Ethephon can promote fruit ripening, stimulate bleeding and regulate sex transformation. It can not only increase the activity of enzymes, but also activate phosphatase and other enzymes related to fruit ripening, so as to promote fruit ripening, inhibit the synthesis of endogenous auxin and delay plant growth.

4. Gibberellin

Gibberellin can make the root system developed, prevent diseases, promote the growth of plant stems and leaves, balance nutrition, contribute to crop growth, spray at flowering stage, protect flowers and fruits, expand fruits, and have more beautiful fruit effects. can effectively relieve crop diseases. When spraying, it is required to spray the mist quickly and spray the liquid evenly, otherwise it will cause the crops to grow, albino, or even die or deform.

5. Fulvic acid

This kind of growth regulator can control the opening of leaf stomata, reduce transpiration, play an important role in drought resistance, improve stress resistance, improve crop quality, and have an effect on common vegetables and fruit crops in rural areas. it can also be mixed with some non-alkaline pesticides to have a synergistic effect.

The above is a full introduction of commonly used growth regulators in agriculture. If farmers are planting crops, they must pay attention to the scientific use of growth regulators to improve the yield and quality of crops.
