What it does
Paclobutrazol blocks gibberellin, the hormone that drives leaf and shoot growth. With less vegetative growth, the tree builds more flower buds. This breaks alternate bearing the cycle where a mango tree fruits one year and skips the next so it can fruit every season.
Key benefits
- Stops the no-fruit year (controls alternate bearing).
- Forces early, uniform flowering useful for commercial orchards.
- Controls excess leaf and shoot growth.
- Improves fruit set, retention, size and overall yield.
- One soil-drench application per season no repeat sprays.
