Physical and chemical properties:
The pure product is white crystal; the color of tech powder is bright yellow to white. The tech powder is melted under the temperature of 238-242οC. The tech powder of chlormequat chloride is easily affected with damp and dissolved in water. While it is difficult to be dissolved In aether and other organic solvents, and it will be melted in the alkali.

It can dissolve in water easily, also dissolve in lower alcohol.
It is affected with damp easily and will decompose meeting Alkalis.
But its aqueous solution is stable.

Oral acute LD50 883 mg/kg for rats; LD50>4000mg/kg (tech). According to our national toxicology grade standard,the chlormequat chloride belongs to the low toxicology plant growth regulators.

1)To increase resistance to lodging (by shortening and strengthening the stem) and to increase yields in wheat,rye, oats, and triticale
2)Also used to promote lateral branching and flowering in azaleas, fuchsias, begonias, poinsettias, geraniums, pelargonium, and other ornamental plants
3)To promote flower formation and improve fruit setting in pears, almonds, vines, olives, and tomatoes;
4)To prevent premature fruit drop in pears, apricots, and plums; etc.
5)Also used on cotton, vegetables, tobacco, sugar cane, mangoes, and other crops.


1) Chlormequat chloride is a low poisonous plant growth regulator, it can be absorbed through leaves, branches, buds, the root system and seeds, control the plant excessive growth and cut down the knot of plant to be short, strong, coarse, root system to prosper and resist lodging.
2) It makes leaves will be greener and thicker,the content of chlorophyll will increase and the photosynthesis will reinforce, which can improve the ratio of set fruit with better quality and higher yield.
3) It can also improve the plant ability to the environment-adjustment, such as drought-resistance, frigidity-resistance, disease and pests-resistance and salinization-resistance .
4) It can be used as the additives in fertilizers such as water flush fertilizer, folia fertilizer, root fertilizer and so on, to raise the absorption to the nutrition and the plant growth.
