2) Melting point: 223oC (tech.)

3) Vapor pressure: < 0.01mPa (20oC)

4) KOW:logP=-2.82 (pH 7)

5) S.g./density: 1.187g/cm3 (tech, 20oC)
6) Stability: a) stable in aqueous media (7d at pH 1 - 2 and pH 12 - 13, 95oC);decomposes at 285oC   

Inhibits the biosynthesis of gibberellic acid.
Used on cotton to reduce vegetative growth and to advance maturation of the bolls;and to inhibit sprouting in onions, garlic and leeks. Used in combination with ethephon to prevent lodging (by shortening the stem and strengthening the stem wall) in cereals, grass seed crops, and flax.

The mepiquat chloride will begin act in 3-5 days after used it, and it can keep the effect in 15 to 25 days( this is decided by the application amount, the rainfall, sensitivity of crop, and the way crop is growing etc.).

Mepiquat chloride can enhance plant’s conduct and systematic function, accelerate the reproductive growth; control the crazy growth and reduce the lateral branch, help the plant have a better shape; strengthen the root system, weighting the fruits and improve the quality. It can widely used on various of fruits trees, cotton, sweat, rice, peanut, corn, potato, grape, legume, vegetables, and flowers.
