Physical and chemical properties: the pure product is crystal, fishy, soluble in low alcohol, insoluble in ether and hydrocarbon organic solvent. It is easy to absorb moisture, decompose at 238-242 ℃, dissolve in water, decompose with alkali, and its aqueous solution is stable.
Toxicity: according to the toxicity classification standard in China, chlorpromazine is a low toxic plant growth regulator. The acute oral LD50 was 883mg / kg in male rats, 4000mg / kg in rats, and there was no adverse effect in rats fed 1000mg / kg for 2 years.
Category: Plant Growth Retardants
Main dosage forms: 50% chlorpromazine, 80% soluble powder, 98% raw powder.
Functional characteristics: chlorpromazine is the antagonist of gibberellin. After using chlorpromazine, it can effectively control the plant growth, promote the reproductive growth, shorten the internode of the plant, and the long plant is short, strong, thick, with developed root system and lodging resistance. At the same time, the leaf color is deepened, the leaf thickening, the chlorophyll content is increased, and the photosynthesis is enhanced, so as to improve the fruit setting rate, quality and yield of some crops. Chlorpromazine can improve the ability of root system to paddle water, affect the accumulation of proline in plant body, and improve the resistance of plant, such as drought resistance, cold resistance, salt resistance and disease resistance. Chlorpromazine can enter the plant through leaves, young branches, buds, roots and seeds, so it can be applied by seed dressing, spraying and watering according to different crops, in order to achieve the best effect.
