Chlormequat

The pure product is white crystal. It has a fishy smell and is insoluble in absolute ethanol, ether, benzene and xylene. Slightly soluble in dichloroethane, isopropanol

Chlormequat is an excellent plant growth regulator, which can be used in crops such as wheat, rice, cotton, tobacco, corn and tomato, to inhibit the elongation of crop cells, but not to inhibit cell division, which can make plants shorter and stems shorter. Thick, leaves turn green, can make crops resistant to drought and waterlogging, prevent crops from growing excessively and lodging, resist salinity and alkali, prevent cotton from dropping bolls, and increase potato tubers.

Definition:

Chlormequat is a plant growth regulator (PGR) widely used in agriculture to control plant growth. It primarily acts as a growth retardant, inhibiting excessive plant growth and promoting sturdier, more compact plants. It is often used in cereal crops, fruits, and ornamental plants to manage growth and improve quality.

Mechanism of Action:

Chlormequat works by inhibiting the biosynthesis of gibberellins, which are plant hormones responsible for promoting cell elongation. By reducing gibberellin production, chlormequat effectively limits excessive vertical growth, leading to shorter, more robust plants. This action helps prevent lodging (falling over) in crops like cereals and improves the quality of fruits and flowers.

Applications:

1. Cereal Crops:
   Chlormequat is commonly used in cereal crops such as wheat and barley to prevent excessive growth and reduce the risk of lodging, which can negatively affect harvest yields and quality.

2. Fruits and Vegetables:
   It is applied to control the growth of fruit trees, such as apples, to promote better fruit size, color, and firmness. In some vegetables, it is used to improve plant structure and enhance harvest quality.

3. Ornamental Plants:
   Chlormequat is also used in ornamental horticulture to control the growth of flowers and plants, ensuring they remain compact and aesthetically pleasing.

4. Turfgrass:
   It is used in turfgrass management to control the growth of grass and maintain a neat, manicured appearance, especially in golf courses and sports fields.

Benefits and Effects:

• Prevention of Lodging:
  By reducing excessive vertical growth, chlormequat helps prevent lodging in crops like cereals, ensuring better harvest outcomes.

• Improved Crop Quality:
  It enhances the quality of fruits and vegetables by promoting better size, color, and firmness.

• Compact Growth:
  Chlormequat ensures that ornamental plants remain compact and well-structured, making them more visually appealing.

Safety and Environmental Impact:

• Toxicity:
  Chlormequat is considered to have low toxicity to humans and animals when used as directed. However, it should be handled with care, and protective equipment should be worn to avoid inhalation or skin contact.

• Environmental Impact:
  As a chemical growth regulator, chlormequat should be used responsibly to minimize its impact on the environment. Over-application or misuse can lead to contamination of soil and water, so it is important to follow recommended usage rates.

Handling and Storage:

• Storage Conditions:
  Chlormequat should be stored in a cool, dry place, away from direct sunlight and heat sources. It should be kept in tightly sealed containers to prevent degradation or contamination.

• Safety Precautions:

  • Wear protective gloves, goggles, and clothing when handling chlormequat.

  • Avoid inhaling dust or spray mist.

  • Keep out of reach of children and animals.

Conclusion:

Chlormequat is an effective plant growth regulator that helps manage plant growth, improve crop quality, and prevent lodging in cereal crops. It is also widely used in ornamental horticulture and turfgrass management. Proper application and safety measures are essential to maximize its benefits while minimizing environmental impact.
