In agricultural production, many products labeled as "growth regulators" are actually nutrient-based fertilizers (such as phosphorus, potassium, boron, zinc, rare earth elements, amino acids, etc.)—collectively known as foliar fertilizers. These can boost yields when the specific nutrients they provide are lacking in the local soil or crop at that time.

Thidiazuron is a compound with unique plant growth-regulating properties, used for cotton defoliation and ripening. Absorbed through the leaves, it influences three key plant hormones—ethylene, auxin, and cytokinin—promoting the formation of a natural abscission layer between the stem and the leaf stalk, thereby causing leaf drop.

Auxins and gibberellins exhibit a synergistic effect in promoting growth. Spraying various plants with a combination of gibberellins and auxins at appropriate concentrations promotes stem elongation;

Combining insecticides is not merely a matter of mixing agents together; it requires scientific and rational formulation based on factors such as application concentration, method of use, and efficacy. The following principles should be strictly observed during formulation
