Paclobutrazol Powder Usage and Synthesis:

The solubility of Paclobutrazol at 20°C is 150g/L in methanol, 110g/L in acetone, 180g/L in cyclohexanone, 100g/L in methylene chloride, 10g/L in hexane, 60g/L in xylene, and 35mg/L in water. , more stable to UV light through roots, stems and leaves can be absorbed by plants. The polyphenols absorbed by the roots run through the xylem to the top of the plant and are mainly transported upwards. When absorbed by the leaves, it moves very slowly and the polyconazole inhibits the growth of the plant or branches. This effect is mainly achieved by inhibiting the synthesis of gibberellin.

Pharmacokinetics of Paclobutrazol Powder:

Paclobutrazol is a triazole plant growth regulator successfully developed in the 1980s as an inhibitor of endogenous gibberellin synthesis. It can also increase the activity of indoleacetic acid oxidase in rice and reduce the level of endogenous IAA in rice seedlings. It significantly reduces the apical growth advantage of rice seedlings and promotes the growth of lateral shoots (tillers). The seedlings showed short, strong and multi-tiller appearance with rich green leaves. The root system is well developed. The anatomical study showed that polyconazole can make the cells of rice seedling roots, leaf sheaths and leaves smaller and increase the number of cell layers of each organ. Tracer analysis showed that rice seeds, leaves, and roots could absorb polyconazole. Most of the uptake of polyconazole by the leaves was retained in the uptake fraction and was rarely transported outward. Low concentrations of carbendazim increased photosynthetic efficiency of rice seedling leaves; high concentrations inhibited photosynthetic efficiency. It increases the respiration intensity of the root system, decreases the respiration intensity of the above-ground part, increases the stomatal resistance of the leaves, and decreases the transpiration of the leaf surface.

Clinical Application of Paclobutrazol Powder:

The agricultural application value of Paclobutrazol lies in its effect on crop growth control. It has the effect of delaying plant growth, inhibiting stem elongation, shortening internodes, promoting plant tillering, promoting flower bud differentiation, increasing plant resistance and improving yield. It is suitable for rice, wheat, peanut, fruit tree, tobacco, rape, soybean, flower, lawn and other crops (plants), and the effect of use is remarkable. Policonazole is a new type of plant growth regulator, which can inhibit the production of gibberellin derivatives and reduce the division and elongation of plant cells. It is easily absorbed by roots, stems and leaves, and conducts through the xylem of plants, and also has fungicidal effect. It has a wide range of activity on graminaceous plants and can make plant stems dwarf at the internodes, reduce collapse and increase yield. Welcome to click to learn more.
