The Study of the Kinetics of Metalaxyl Accumulation and Dissipation in Durian ( L.) Leaf Using High-Performance Liquid Chromatography (HPLC) Technique.

Metalaxyl is an effective approach to control infection in durian plantation. However, inappropriate metalaxyl usage may increase production cost, pathogen with fungicide resistance, and environmental toxicity. This study established and validated a simple and reproducible procedure to measure metalaxyl concentration in the durian leaf using HPLC.
