Uses and synthesis of paclobutrazol powder

paclobutrazol powder is a kind of inhibitory triazole plant growth regulator, and paclobutrazol CAS 76738-62-0 has a long lasting effect in soil. In order to reduce the inhibition effect on the later crops, the cultivated plots should be carefully tilled after harvest.

Functions of paclobutrazol powder

Dwarfing plants and controlling plant type:
Dwarfing and dense planting of fruit trees: In fruit tree production, paclobutrazol is often used to dwarf apple trees, pear trees, peach trees, citrus trees and other fruit trees to control the size of the crown, facilitate management and picking, and increase the yield per unit area. Dwarfing and dense planting is also conducive to improving the ventilation and light conditions of the orchard and reducing the occurrence of pests and diseases.
Dwarfing of ornamental plants: In the production of ornamental plants such as potted flowers, grass flowers, and hedge plants, paclobutrazol is used to control the height of the plant type, making the plants short, strong and compact, and improving the ornamental value. For example, dwarf chrysanthemums, dwarf petunias, dwarf coleus, etc.
Regulating the growth of lawn grass: In lawn management, paclobutrazol is used to inhibit the excessive growth of lawn grass, reduce the number of mowing times, reduce maintenance costs, and keep the lawn flat and beautiful. It is especially widely used in places such as golf courses and football fields where high lawn quality requirements are required.

Promoting flower bud differentiation and promoting flowering and fruiting:
Promoting flower bud differentiation of fruit trees: paclobutrazol promotes the differentiation of flower buds of fruit trees, increases the amount of flowers, and lays the foundation for high yields. At the same time, dwarfing trees is also conducive to nutrient accumulation and flower bud differentiation.
Flower promotion: For some flowers, paclobutrazol can break the apical dominance, promote the growth of lateral branches and the formation of flower buds, bloom earlier, and increase the number of flowers.
Improve fruit setting rate: paclobutrazol increases pollen vitality, promotes pollination and fertilization, and increases fruit setting rate. At the same time, dwarfing plants is also conducive to the transfer of nutrients to reproductive organs and promotes fruit development.

How to use of paclobutrazol powder.

Foliar spray: It is the most commonly used method. Spray the paclobutrazol solution evenly on the surface of plant leaves. The spray should be even and thorough to avoid repeated spraying or missing spraying. The spraying time should be selected in the morning or evening when it is sunny and windless, and avoid spraying in high temperature, strong light or rainy days.

Soil treatment: Apply paclobutrazol granules or wettable powder to the soil and absorb it through the plant root system. Soil treatment has a long lasting effect, but the dosage is large and the cost is high. It is generally used for soil treatment at the base of fruit trees or soil treatment in nurseries.

Seed treatment: Soak the seeds in paclobutrazol solution for a certain period of time, or mix the seeds with paclobutrazol. Seed treatment uses a small amount of medicine, has a long-lasting effect, and is easy to operate. It is suitable for field crops such as rice, wheat, and corn.

Seed soaking: Soak the roots of seedlings or seedlings in paclobutrazol solution for a certain period of time, and then transplant them. Seed soaking is mainly used in the seedling stage to promote the seedlings to be short and strong.

Production methodprocess of paclobutrazol powder

paclobutrazol powder was prepared from p-chlorobenzaldehyde and 3, 3-dimethyl-2-butanone by hydrogenation, bromination, reaction with 1, 2, 4-triazole, and reduction with sodium borohydride.
