What are the agents that promote the expansion of plant roots and stems?

Chloroformamide and Choline chloride, and 1-Naphthyl Acetic Acid (NAA)

The main types of plant root and stem expansion agents include chlorformamide and choline chloride/naphthyl acetic acid.

Choline chloride is a synthetic plant growth regulator that can promote the rapid expansion of underground roots and tubers, improve yield and quality. It can also regulate the photosynthesis of leaves and inhibit photorespiration, thereby promoting the expansion of underground tubers.

1-Naphthyl Acetic Acid (NAA) has the function of promoting the formation of root systems and adventitious roots, can promote the expansion of underground tubers, and improve the resistance of crops to stress, such as cold resistance, waterlogging resistance, and drought resistance.

‌When using Choline chloride, you need to pay attention to the following points:
First, Choline chloride cannot supplement nutrition for crops, so it needs to be used in conjunction with high-phosphorus and high-potassium fertilizers. Second, Choline chloride should not be mixed with alkaline substances and should be prepared and used immediately. Finally, avoid high temperatures and scorching sun when spraying. If it rains within 6 hours after spraying, reduce the spraying rate by half and spray again.

Precautions for the use of 1-Naphthyl Acetic Acid (NAA) include:
the agent must be prepared strictly according to the concentration used, and avoid excessive use, otherwise it will inhibit the tuber expansion of crops. 1-Naphthyl Acetic Acid (NAA) is better when mixed with Choline chloride, and is suitable for underground tuber crops such as garlic, peanuts, potatoes, sweet potatoes, etc.

Forchlorfenuron is a plant growth regulator, also known as KT30 or CPPU.

These expansion agents are widely used in agricultural production and can significantly increase crop yields, especially in the application of root crops such as sweet potatoes, potatoes, radishes, yams, etc. After use, the number of underground tubers increases, the size increases, and the yield and quality are significantly improved, and even a 30% increase in yield can be achieved.

In addition, the use of expansion agents requires attention to reasonable dosage and methods to avoid adverse effects on plants. Experts point out that the growth enhancer itself is harmless to human health, but improper use may have adverse effects on plants and fruits.
