| Molecular Formula: C7H16NCl Chemical name: N, N= dimethylpiperidinium Chloride specification: 99% Tech.,985 Tech.,97% Tech. (w/w) Physical & Chemical Characteristics: Appearance: White to slight yellow crystalline solid;Melting Point: 223℃, Decomposition Point: 285℃;; <1x10-7 mbar (20℃);Solubility in gram in every 100g solvent at 20℃. Water; >100g; Ethanol: <16.2g; Acetone, ether, ethyl acetate, cyclohexame and olive oil: <0.1g.;Density: 1.87 (20℃); Stable to heat. Shelf life:: 2 years under the cool, shade and dry storage conditions. Toxicity: In accordance with Chinese toxicity grade scale of agrochemical, mepiquat chloride is a low toxicity plant growth regulator. Acute Toxicity: Adult Rat Oral LD50 =1490mg/kg; Dermal LD50 =7800mg/kg; Inhalation LC50 =3.2mg/L Toxicity to Eye and Skin: No irritatiion to rabbit skin and eyes. Accumulation Toxicity: Mepiquat chloride accumulates little in animal body and doesn't cause mutation, aberration and cancer under experimental conditions. No abnormality accurs in the 3 - generation reproduction experiment of adult rat. Chronic Toxicity: The no-effect dosage is 3000ppm in the 2-year chronic feeding experiment of adult rat. Mode of action & functions: This product is kind of plant growth regulator . It mostly restrain the biosynthesis of gibberellic acid inside crops when being absorbed by leaves and roots. In this way it can restrain the elongation of cell, stay the growth of nutrition; make plants shorter and increase content of chlorophyll. This also increases assimilation of leaves and adjusts distribution of outcome inside plants. Adjust growth of cottons; control model of plant; harmonize develop of nutrition; reduce falling off of boil, increase boil number and weight of each plant, increase output. We can see from research that it could increase number and weight of boil of the middle and lower part of plant. Make wheat short but strong and increase the production. Restrain elongation of Culm , make plant to be wide and strong, avoid lodging. The color of leaves will be darker, accumulation of nutrition become increased, number of fringe and output both increased obviously. When crops were sprayed in anthesis, we can raise their fruit rate and kilo grain weight. For peanut, mung bean, tomato, watermelon and cucumber, it can help the transportation of photosynthesis outcome to flower and fruit. Avoid falling off, increase fruit rate. Help the intumescences of rhizome Increase content of grape sugar and out put. It can obviously restrain elongation between tips, reduce consume of nutrition, facilitate accumulation of sugar and intumescences of animus. |
