What are the commonly used types of growth regulators in agriculture?

When farmers plant crops, they often use growth regulators, which can promote or control crop growth and development, and there are many growth regulators commonly used on the market today, each playing a different role. Through the use of growth regulators, the growth and development of crops can be regulated in time and space, so what are the commonly used growth regulators in agriculture? Let's find out together below!

1. Sodium nitrophenolate

This 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.

This growth regulator is suitable for application to fertilizers (foliar fertilizers, compound fertilizers, water-flush fertilizers, base fertilizers, bottom fertilizers, etc.). Under a suitable temperature environment, it takes effect in just one day, and after use, there is no need to add other similar synergists.

2. Brassinolide

This type of growth regulator is mainly used for seed soaking and stem and leaf spraying. It can promote rooting, promote growth, lift seedlings, strengthen seedlings, turn yellow leaves and diseased leaves green, protect flowers and fruits, promote fruit expansion and early ripening, reduce diseases and alleviate phytotoxicity, and coordinate nutritional balance. For dead seedlings and rotten roots caused by phytotoxicity or diseases, its use effect is very significant, and it is very helpful for promoting growth and increasing yield. To a certain extent, it can also delay leaf aging and improve photosynthesis.

3. Ethephon

Ethephon can promote fruit ripening, stimulate wound flow, and regulate sex transformation. It can also increase enzyme activity. When fruits ripen, it can also activate phosphoesterase and other enzymes related to fruit ripening, thereby promoting fruit ripening. It can also inhibit the synthesis of endogenous auxin and delay plant growth.

4. Gibberellin

Gibberellin can make the root system well developed, prevent the occurrence of diseases, promote the growth of plant stems and leaves, and also make nutrition balanced and help crop growth. Spraying during the flowering period can protect flowers and fruits, and can also make fruits expand and have a fruit-beautifying effect. It can effectively relieve crop diseases. When spraying, fine mist and quick spraying are required, and the liquid should be sprayed evenly, otherwise it will cause excessive growth, whitening, or even death or deformity of crops.

5. Fulvic acid

This type of growth regulator can control the opening degree of stomata on crop leaves, reduce transpiration, play an important role in drought resistance, improve stress resistance, and improve crop quality. It is effective for the relatively common vegetable and fruit crops in rural areas today, and can also be mixed with some non-alkaline pesticides, with a synergistic effect.

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