Physical and Chemical Properties | Plastic pigment plastic hormone insoluble in water, soluble in ethanol and so on. It is sensitive to UV photolysis, especially its free acid and amide salts, which are unstable when exposed to heat. Non-toxic, the final decomposition product is carbon dioxide, no pollution to the environment, not a long-term inhibitor. |
Use | For pharmaceutical applications |

Mechanism of action | The mechanism of action of orthopotin is to inhibit the synthesis of endogenous auxin and gibberellin in plants, as well as the polar conduction and lateral transport of auxin. The inhibitory effect is greater than gibberellin. It can also inhibit the mitosis of meristem cells, promote the dwarfing of stems, and cause morphological and organ abnormalities, this inhibition injury is recoverable. At the same time, it can change the tropism, phototropism and apical advantage of plants. |
Use | Plastic hormone is a new type of multi-purpose plant growth regulator. Its active ingredient is 2-chloro-9-hydroxyfluorene-9-carboxylic acid and its derivatives, low toxicity, do not cause environmental pollution, and its physiological effect is similar to abscisic acid. It can inhibit cell mitosis, inhibit the growth of terminal buds, and promote the occurrence of germ, the application methods include foliar spraying and root irrigation, and the dwarfing effect is equivalent. for pharmaceuticals |
