ABSTRACT

A comparison of the dissipation of chlorpyrifos in a Malaysian agricultural soil was undertaken using data from a field experiment and simulation by the PERSIST model. The study was carried out at an oil palm estate located close to the Kuala Lumpur International Airport (KLIA), Sepang, Selangor (for field experiment). The plots were treated with chlorpyrifos at the manufacturer’s recommended dosage. Soil samples were collected according to the sampling schedule at intervals of 0, 1, 3, 7, 14, 21, 30, 60 and 90 days. Residues of chlorpyrifos in soil from the field trial were analyzed in the laboratory. Simulation of chlorpyrifos leaching and persistency was done using two computer-run software VARLEACH and PERSIST. Generally, predicted data for chlorpyrifos residue obtained using the VARLEACH and PERSIST models was found to be well matched with the observed data from the field trial. The PERSIST Prediction for chlorpyrifos residue in soils planted with oil palm trees was found to be accurate and conformed to the results observed in the field trial.

ABSTRAK

Perbandingan pelesapan chlorpirifos dalam tanah pertanian Malaysia telah dijalankan dengan menggunakan data daripada kajian lapangan dan simulasi dengan model PERSIST. Kajian ini telah dijalankan di sebuah ladang kelapa sawit yang terletak berhampiran dengan Lapangan Terbang Antarabangsa Kuala Lumpur (KLIA), Sepang, Selangor (untuk kajian lapangan). Plot telah dirawat dengan chlorpirifos pada dos yang disyorkan pengeluar. Sampel tanah telah dikumpulkan mengikut jadual persampelan pada sela 0, 1, 3, 7, 14, 21, 30, 60 dan 90 hari. Sisa chlorpirifos dalam tanah daripada percubaan lapangan dianalisis di dalam makmal. Simulasi chlorpirifos larut lesap dan ketegaran dilakukan menggunakan komputer melalui perisian VARLEACH dan PERSIST. Secara umumnya, peramalan data untuk sisa chlorpirifos diperoleh menggunakan model VARLEACH dan PERSIST didapati padan dengan data yang dicerap daripada percubaan lapangan. Ramalan PERSIST untuk sisa chlorpirifos dalam tanah yang ditanam dengan pokok kelapa sawit didapati tepat dan serupa dengan keputusan yang diperhatikan dalam percubaan lapangan.
