The four growth control agents, Paclobutrazol, Uniconazole, Chlormequat Chloride, and Mepiquat chloride, all control plant growth in a short period of time by inhibiting the synthesis of Gibberellic acid in plants. I

Paclobutrazole (Paclo) is use in various crops such as rice, wheat, vegetables, and fruit trees. Paclobutrazole (Paclo) is a broad-spectrum plant growth retardant. It can inhibit the synthesis of endogenous gibberellins in plants and reduce the division and elongation of plant cells.

Compound sodium nitrophenolate (Atonik) is a high-efficiency plant growth regulator.It has the characteristics of high efficiency, non-toxicity, no residue, and wide application range.It is called the "Green Food Engineering Recommended Plant Growth Regulator" by the International Food and Agriculture Organization. no side effects to humans and animals.

Thidiazuron (TDZ) is a nutrient mainly compose of a mixture of potassium dihydrogen phosphate and thiadiazuron. It has multiple effects on the growth and development of fruit trees: increasing yield, improving quality, improving disease resistance, etc. Thidiazuron (TDZ) can promote photosynthesis, improve plant nutrient utilization, increase the number of flower buds and fruit quality.
