Plasticine is a kind of fluorene growth regulator, also known as morphogen and chlordane. Pure product is a white odorless crystalline solid. Safe for human and livestock (acute oral LD50 in rats >; 128 mg/kg), which is unstable under ultraviolet irradiation and easy to decompose when heated. No pollution to the environment.

Plasticine can be absorbed by seeds, leaves, tender stems and roots. After transportation, it accumulates in active parts, delaying germination and hindering seedling growth, inhibiting stem elongation and controlling apical dominance, thus prolonging flowering, fruiting and maturity. In vegetable fields, it can be used to harvest cauliflower early, improve the quality of radish, reduce hollowness and form seedless fruits of tomatoes and cucumbers.
