Generally, it refers to a 50% thiophene wettable powder. In plants, it can stimulate ethylene synthesis, improve the decomposition activity of pectin and cellulase. The cell wall of plant cells is composed of pectin and cellulose. After spraying thiophene, the cell wall is dissolved, and the external manifestation is mature leaf shedding, accelerating cotton boll opening.

Generally, it refers to 0.15% -0.5% thiamethoxazole and its complex soluble agents. As a cytokinin, when thiamethoxazole is absorbed by the plant body, it can effectively promote the activity of cell proteins and enzymes, thereby accelerating cell division and plant growth.

When the cytokinin/auxin ratio in the plant body is greater than 1, the plant body begins to induce callus tissue for bud development, which then differentiates into flower buds, leaf buds, and mixed buds. Flower buds become flowers, leaf buds become leaves, and mixed buds can become branches.
