Which plant growth regulator can be use to grow tomatoes to promote fruit setting and inhibit leggy growth?



In the process of planting tomatoes, we often encounter low fruit setting rate and leggy tomatoes.    
When encountering this situation, we don’t have to worry,We can use an appropriate amount of plant growth regulators to solve this series of problems.

1.    Ethephon
One is to curb excessive growth. During the seedling cultivation period, due to high temperature, high humidity and untimely transplantation or colonization, the seedlings will grow too long.   
Spraying the leaves with a certain amount of ethephon can control the leggy growth and make the seedlings strong, with thickened leaves, strong stems, developed root systems, and enhanced stress resistance.

2.   Gibberellic acid(GA3)
Can promote fruit setting.During the flowering period, spray or dip flowers at 10-50 mg/kg once to preserve flowers and fruits, promote fruit growth and prevent hollow fruits.

3.    Paclobutrazol(Paclo)
Can prevent excessive growth.Spraying 150 mg/kg paclobutrazol when tomato seedlings are overgrown can control overgrowth, promote reproductive growth, facilitate flowering and fruit setting, advance the harvest period, and increase production.

4.    Chlorocholine chloride(CCC)
In the process of raising tomato seedlings, sometimes the seedlings are too long due to reasons such as too high outside temperature, too much fertilizer and water, too high density, too fast growth, etc.    In addition to dividing the seedlings and planting them, controlling watering, and strengthening ventilation, can be use when 3 to 4 leaves or 7 days before seedlings planting, apply 250-500mg/kg Chlorocholine chloride(CCC)soil to prevent excessive growth.
