Key Benefits of Syngenta Cultar
- Helps control excessive vegetative growth in mango trees.
- Supports early formation of terminal and fruit buds.

How Does Cultar Work?
Paclobutrazol inhibits the biosynthesis of gibberellins, plant hormones responsible for vegetative growth. After application through the soil, it is absorbed mainly through the roots and moves within the plant to the growing tissues. This reduces excessive shoot growth and helps the mango tree shift towards terminal bud and flowering development.
Recommended Dosage for Mango
| Age of Mango Tree | Recommended Dose | Water for Dilution |
|---|---|---|
| 7–15 years | 15 ml per tree | 5–10 litres |
| 16–25 years | 20 ml per tree | 5–10 litres |
| Above 25 years | 25–40 ml per tree | 5–10 litres |
Application Timing: According to the registered label, Cultar should be applied after mango fruit harvest. The period from July to October is indicated for application.
How to Apply Syngenta Cultar
Dilute the recommended quantity of Cultar in 5–10 litres of clean water. Apply it around the mango tree approximately 30 cm away from the trunk in a shallow furrow around 5–10 cm deep, then cover the treated area with soil. It can also be applied as a soil-collar drench as directed on the product label.
