Cultar Plant Growth Regulator – Paclobutrazol 23% SC by Syngenta

What is Cultar Plant Growth Regulator?

Cultar® is an advanced plant growth regulator (PGR) from Syngenta designed to optimize plant development by regulating hormone activity. Its key ingredient, Paclobutrazol (23% SC), works by inhibiting gibberellin synthesis, reducing unwanted vegetative growth, and redirecting plant energy toward flowering and fruiting for better yield potential.

 How Cultar Enhances Crop Growth

 Mode of Action – Hormonal Regulation

• Paclobutrazol inhibits the biosynthesis of gibberellins, the plant hormones responsible for cell elongation and vegetative growth.

• By reducing shoot length and vigor, the plant allocates more energy to flower induction, fruit set, and reproductive development.

 Key Benefits of Cultar

• Controls excessive vegetative growth, resulting in compact plant structure.

• Promotes early and uniform flowering to improve crop performance.

• Enhances fruit size, colour, and set, contributing to better marketable yield.

• Reduces pruning labor and crop management costs.

• Improves nutrient utilization and stress tolerance.

🟢 Targeted Purpose (Plant Growth Regulator)

• Vegetative Growth Control

• Flowering Enhancement

• Fruit Set & Yield Improvement

• Plant Stress Management

🟢 Suggested Crops

Cultar is widely used across horticultural and field crops where growth regulation and improved reproductive performance are desired:

• Mango

• Pomegranate

• Apple

• Grapes

• Citrus

• Cotton

• Vegetables & Ornamentals

• Other fruit and high-value crops where vegetative balance is important

🟢 Dose & Application

Recommended Dose

• For trees:

  • Mango (7–15 yrs): ~15–20 ml/tree

  • Mango (16–25 yrs): ~20–30 ml/tree

  • Mango (>25 yrs): ~30–40 ml/tree

• For other crops:

  • 5–8 ml per 15 L water depending on crop type.

Method of Application

• Soil drench or soil collar application near the root zone.

• Can be used before flowering or when excessive vegetative growth is observed.

• Follow integrated crop management practices for best results.
