Prohexadione calcium is a new plant growth regulator. It can inhibit the synthesis of gibberellic acid through plant seeds, roots and foliar absorption. It can shorten the stem extension of many plants. It works by soaking seeds, watering, and spraying foliar treatment. Compared with the currently widely used triazole retarders, prohexadione calcium has no residual toxicity to crop plants and no pollution to the environment, so it is possible to replace triazoles. Growth retardant has wide application prospects. 
 

Promote growth, can shorten the stem extension of many plants, control the growth of crop nodes, make the stem thick, plant dwarf, reduce and prevent lodging; promote growth, promote the growth of lateral buds and roots, and keep the stems and leaves green, Leaves stand upright; control flowering time, increase fruit setting rate, and promote fruit ripening. It can also improve the plant's stress resistance, enhance the plant's resistance to disease, cold and drought, reduce the herbicide's phytotoxicity, thereby improving harvest efficiency.

Prohexadione calcium can significantly shorten the stalk height of all rice cultivars, and at the same time has the effect of promoting the development of spikes and grains and increasing the yield of rice. Low-dose prohexadione calcium can regulate the growth of cereals such as rice, barley, wheat, Japanese carpet grass, ryegrass, etc., and has significant resistance to lodging and dwarfing. It is also used in cotton, sugar beet, cucumber, chrysanthemum, cabbage, carnation, soybean, citrus, apple, etc. It has obvious growth inhibitory activity.
