Plant Growth Regulators: Advanced Agro Chemicals For Crop Performance

Introduction: Understanding Plant Growth Regulators (PGRs)

Modern agriculture demands high crop yield, quality produce, and efficient farming practices.
Plant Growth Regulators (PGRs) are advanced agrochemicals that control plant growth and development at a physiological level.

Unlike fertilisers, which supply nutrients, PGRs regulate plant processes like flowering, fruiting, seed germination, and stress tolerance. Farmers use them to improve crop performance, increase resistance against environmental stresses, and achieve market-ready harvests.

Chemical Bull, a trusted agrochemical trading company, provides high-quality PGRs and related products worldwide.

What is Plant Growth Regulator (PGR)?

Plant Growth Regulators (PGRs) are natural or synthetic chemicals that regulate plant growth and development.
Unlike fertilisers, which provide nutrients, PGRs regulate internal plant processes such as:

• Flowering

• Fruiting

• Seed germination

• Root growth

• Stress tolerance

Types of Plant Growth Regulators

1. Auxins
   
   

• Promote root growth and fruit setting.

• Commonly used in vegetables, grapes, and apples.

• Works well with fertilisers for increased nutrient uptake.

• Explore Crop Protection Chemicals
  
  

2. Gibberellins
   
   

• Stimulate stem elongation and improve seed germination.

• Increase yield in sugarcane, grapes, and cereals.

• Example: GA3-based PGRs used for uniform growth.
  
  
  

3. Cytokinins
   
   

• Delay leaf senescence and improve nutrient efficiency.

• Promote balanced growth and flowering in vegetables and fruit crops.
  
  
  

4. Ethylene
   
   

• Regulates fruit ripening for uniform harvests.

• Helps manage leaf drop in seasonal crops.
  
  
  

5. Abscisic Acid (ABA)
   
   

• Enhances drought and salinity tolerance.

• Controls seed dormancy for synchronised germination.

Applications of Plant Growth Regulators (PGRs)

PGRs are applied according to crop type and growth stage to improve efficiency, quality, and stress resistance.

1. Seed Treatment
   
   

• Gibberellins and cytokinins improve seed germination and early vigour.

• Ensures uniform seedling emergence.
  
  
  

2. Foliar Application
   
   

• Auxins and cytokinins enhance flowering, fruit set, leaf health, and photosynthesis.

• Crops: Tomatoes, grapes, vegetables, fruit orchards.
  
  
  

3. Soil Application
   
   

• Promotes strong root development and nutrient absorption.

• Effective for sugarcane, wheat, and maize.
  
  
  

4. Stress Management
   
   

• ABA and cytokinins help plants cope with drought, salinity, and heat stress.
  
  
  

5. Crop Architecture Control
   
   

• Regulates stem elongation, branching, and leaf size for optimal plant shape.

• Useful in cereals and horticultural crops.
  
  

6. Post-Harvest & Ripening Control
   
   

• Ethylene-based PGRs regulate fruit ripening.

• Reduces post-harvest losses, increases shelf life.
