Abstract
The degradation of pesticide in mango ‘Mahajanaka’ from Wiang Nong Long district, Lumphun province, was studied.
Profenofos and carbaryl residue of mango fruits was measured after dip in profenofos + carbaryl in 500 and 850 mg L-1, respectively.
The results found that at 25°C profenofos degraded faster than at 5 and 13°C. The concentrations of profenofos were 0.23, 0.29 and 0.46 mg kg-1 after dip in pesticide at 6, 15 and 18 days, respectively.
The carbaryl residue was non-detectable in the mango stored at 13 and 25°C for 3 days, while in the stored mango in 5°C, 0.13 mg kg-1 of the residue was still detected, which is lower than the MRL of Thai Agricultural Standard, established by the National Bureau of Agricultural Commodity and Food Standards.
