PEP-STAR 40 (Paclobutrazol 40% SC) is a powerful plant growth regulator containing 40% paclobutrazol in suspension concentrate (SC) form. This product is formulated to inhibit excessive vegetative growth, redirecting energy toward flowering and fruiting for increased yields and improved crop quality. PEP-STAR 40 is particularly beneficial for managing growth in fruit trees and ornamental plants, enhancing productivity and plant structure.

Mode of Action:

Paclobutrazol, the active ingredient in PEP-STAR 40, inhibits gibberellin biosynthesis, a hormone responsible for cell elongation. By limiting gibberellin production, it reduces stem elongation and promotes compact growth, which redirects resources to flower and fruit development. This results in shorter internodes, stronger branches, and a greater focus on reproductive growth, optimising fruit size and yield.

Benefits of Paclobutrazol 40% SC:

Reduces excessive vegetative growth for manageable plant size.
Promotes more concentrated flowering and fruiting.
Enhances fruit size, color, and overall quality.
Strengthens plant structure with compact growth.
Improves crop yield and market value

Recommended Dosage:

Dosage of Paclobutrazol varies according to the age of Mango tree:

For below 10 Years = 8 ml
For above 10 Years = 16 ml

Method of Use:

Paclobutrazol is much more effective when used with the Collar-Drench method. With the recommended quantity of Paclobutrazol and 0.5–2 litres of water per tree, apply this to the soil or trunk crack line around the base of the trunk. Or, Apply Paclobutrazol as Soil Drench. Dilute the recommended quantity of Paclobutrazol in clean water of 10 litres and apply in a furrow 5 cm deep, about 2 to 3 feet away from the trunk; fill up with soil after application. Or, by foliar spray application, the new flowering can be treated with 1000–2000 ppm after the sunset.
