Product details
Paclobutrazol is a new type of plant growth regulator that 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 is conducted through the xylem of plants, and has a bactericidal effect. It has a wide range of activity on gramineous plants, can make plant stem internodes become short and strong, reduce lodging, and increase yield. It is a new, efficient, low-toxic plant growth regulator with a broad-spectrum bactericidal effect.
Applications/Functions of paclobutrazol powder
Paclobutrazol is an inhibitor of endogenous gibberellin synthesis, which can significantly weaken the apical growth advantage, promote the growth of lateral buds (tillers), thick stems, and dwarf and compact plants. It can increase the content of chlorophyll, protein and nucleic acid, reduce the content of gibberellin in the plant, and can also reduce the content of indoleacetic acid and increase the release of ethylene. Paclobutrazol also has the effect of dwarfing peach, apple and citrus plants, controlling shoots and early fruiting. Herbs and woody flowers treated with paclobutrazol have a compact plant shape and are more ornamental. Paclobutrazol has a long lasting effect in the soil. The drug plots should be plowed after harvest to reduce the inhibitory effect on subsequent crops.
Physicochemical Property of paclobutrazol powder
paclobutrazol Raw Materials are white crystalline solids.
Product method of paclobutrazol powder
The reaction of 1-(p-chlorophenyl)-2-(1,2,4-triazol-1-yl) propionyl chloride with tert-butylmagnesium bromide and then reduction with sodium borohydride can produce paclobutrazol. Although this method has few production steps, the raw materials are hard to come by and are easily hydrolyzed, so it needs to be carried out under anhydrous conditions.
