Young ‘Carabao’ mango trees which could not be forced to flower with potassium nitrate (KNO3) can be treated with the plant growth regulator paclobutrazol. Paclobutrazol is applied to 7-10 year-old grafted ‘Carabao’ mango trees, regardless of the strain, planted in a square system at a 7 m distance from each other. The trees are drenched at a rate of 1.0 gm/m canopy diameter. The trees can then be forced to flower 120 to 180 days after paclobutrazol is applied using 2% KNO3. Through this technology, mango trees as young as 4 years old can be forced to flower with up to 100% intensity. This technology is currently used in ‘Carabao’ mango trees 4-15 years old, which do not respond to KNO3 treatment.
