Abstract The effects of paclobutrazol at different rates on flowering, fruit and quality of Mao Luang were compared to investigate the residue of the chemical in soil and its products. Uniform plants of of Fah Prathan variety with 6 years old were selected in the farmer plantation. The treatments were significantly different for flowering development, inflorescence per branch, inflorescence length percentage of fruit maturity and yield per plant. Paclobutrazol at the concentration of 200 ppm had the highest flower induction, fruiting and quality of Mao Luang fruits, which showed good physical characteristics, and chemical compositions of fruits. This concentration had the highest total flavonoid content in fruits. Paclobutrazol residues in soil, leaf and fruits were lower than the maximum limited residues. The results indicated that application of paclobutrazol on Mao Luang is safe for consumers.
