What is the Chlormequat Chloride?

Chlormequat chloride is a kind of plant growth regulator of quaternary ammonium salt. CAS number 999-81-5 ,The chemical formula C5H13Cl2N. Appearance of white crystal, fishy odor, easy delixing, soluble in water, soluble in propyl alcohol. It is stable in neutral or slightly acidic medium and decomposed by heat in alkaline medium.

chlormequat chloride is an excellent plant growth regulator, can be used in wheat, rice, cotton, tobacco, corn and tomatoes and other crops, inhibit crop cell elongation, but not inhibit cell division, can make plants shorter, stem thicker, leaf color green, can make crops drought and waterlogging tolerance, prevent crops from falling, salt and alkali resistance, but also can prevent cotton drop, can make potato tuber increase.

Chlormequat chloride use

  1. It can control the vegetative growth of plants (that is, the growth of roots and leaves), promote the reproductive growth of plants (that is, the growth of flowers and fruits), and improve the fruit setting rate of plants.
  2. It can regulate the growth of crops, promote tillering, increase ear yield, increase chlorophyll content after use, make the leaves dark green, strengthen photosynthesis, thicken leaves, and develop roots.
  3. It can regulate the growth of crops, promote tillering, increase ear yield, increase chlorophyll content after use, make the leaves dark green, strengthen photosynthesis, thicken leaves, and develop roots.
  4. It can improve the water absorption capacity of roots, significantly affect the accumulation of proline (which plays a stable role in cell membrane) in plants, and help to improve the resistance of plants, such as drought resistance, cold resistance, saline-alkali resistance and disease resistance.
  5. The number of stomata in leaves decreased and transpiration rate decreased, which could increase drought resistance ability.
  6. It is easy to be degraded by enzymes in soil, and is not easy to be fixed by soil, so it does not affect soil microbial activity or can be decomposed by microorganisms. It does not contain chlorine or bromine atoms and has no ozone depletion effect, so it does not harm the environment.

Chlormequat chloride method of application

The effect of this growth regulator is the opposite of that of gibberellin, it is an antagonist of gibberellin, and its physiological function is to control the vegetative growth of the plant.

  1. Spraying with a concentration of 4000-5000 mg/l in the growing points of cabbage (lotus white) and celery can effectively control bolting and flowering.
  2. When peppers and potatoes begin to have a barren trend, in the bud to blossom stage, potatoes with 1600-2500 mg/l of dwarf hormone spray leaf surface, can control the ground growth and promote yield, pepper with 20-25 mg/l of dwarf hormone spray stem and leaves, can control the barren growth and improve fruit setting rate.
  3. Tomato seedling with 50 mg/l of water on the surface of the soil, can make the tomato plant compact and early flowering. If the tomato is found to be barren after planting and transplanting, 500 mg/l of the diluent can be poured according to 100-150 ml per plant, 5-7 days will show the efficacy, 20-30 days after the efficacy disappears, return to normal.
