Mepiquat Chloride in pure form is white crystalline and odorless. The original drug is white or light yellow powder. Stored at room temperature for two years, its active ingredients are basically unchanged, but due to the high susceptibility to moisture-absorbing lumps, which does not affect its efficacy. Its melting point is greater than 350 ℃ (285 ℃ decomposition), the vapor pressure (20 ℃) is less than 10 ^ (-5) Pa, solubility (20 ℃), Mepiquat Chloride is soluble in water, ethanol solubility of 16.2%, while in ethyl acetate and olive oil solubility are less than 0.1%.
Mepiquat Chloride can be absorbed through the leaves, roots and stems of the plant and is conducted throughout the plant. It reduces the activity of gibberellins in the plant and inhibits cell elongation and fleshy shoot growth, thereby controlling plant growth and reducing plant height and fruiting branch length. In addition, Mepiquat Chloride can improve plant ventilation, reduce nutrient consumption, promote the growth of main roots, make the root system developed, and enhance the plant's resistance to collapse.Mepiquat Chloride can also promote the synthesis of chlorophyll, improve the efficiency of photosynthesis, so that more photosynthetic products are delivered to the fruit.
Mepiquat Chloride is widely used in a variety of crops such as cotton, wheat, rice, peanuts, corn, potatoes, grapes, vegetables, beans and flowers. Example:
Cotton: Using Mepiquat Chloride can inhibit the growth of superfluous buds and control the plant growth.
Rice: Mepiquat Chloride can effectively reduce the height of plants, enhance the ability of resistance to fall, and has the effect of ripening and drought resistance.
Grapes: Spraying Mepiquat Chloride on grapes during the flowering period can shorten branch internodes, increase the depth of leaf color, promote fruit neatness and sweetness, and advance the ripening period.
