Abstract
Paclobutrazol is a plant growth regulator that is used to counter alternate bearing habit of mango (Mangifera indica L.). The uptake and persistence of paclobutrazol residues in mango fruits and soil respectively, was studied following its application at tree basin soil @5 and 10Â g a.i. per tree for three consecutive years. Residues of paclobutrazol were found in unripe mango fruits at levels below permissible level while the same was generally not detected in fully mature mango fruits ready for harvest. There was no effect of consecutive yearly applications on the amount of paclobutrazol residues in mango fruit. However, the residues of paclobutrazol were found in tree basin soil (0-15Â cm) at the end of each season and there was a small increase in the amount of residues corresponding to the number of yearly applications that had been made. GC-MS analysis confirmed that the sample peaks obtained corresponded to paclobutrazol residues present in mango and soil.
