Sumitomo Celstar – Paclobutrazol 23% SC for Mango Flowering Management

Sumitomo Celstar is a systemic plant growth regulator containing Paclobutrazol 23% SC for use in mango. It helps regulate vegetative growth and supports flowering, fruit setting, and management of alternate or irregular bearing when used according to the official product label.

Technical Details

Mode of Action

Paclobutrazol is absorbed through the roots or stem tissue and translocated to sub-apical meristems. It inhibits gibberellin biosynthesis, which helps regulate shoot growth by reducing internode elongation and encouraging earlier terminal bud formation. This growth-regulating action supports more balanced vegetative development and flowering in mango.

Recommended Crops, Target Problems & Dosage

Sumitomo Celstar is recommended for mango. The verified product guidance is based on mango tree age.

Dosage should be diluted in 5–10 litres of clean water per tree, following the official product label.
